CR Series Mobile Extraction and Filtration Systems

Mobile extraction and filtration systems are deployed in clean rooms and clean room areas in addition to sometimes extremely intricately installed RLT systems. In the direct vicinity of production and packaging machines they remove fine dust particles which can negatively influence the quality of end products.

Normally, these particles are adsorbed by means of special storage filters which need to be replaced or changed after a certain period of operation. The passing out and subsequent passing in of the extraction and filtration system out of and back into the clean room to change the filter costs time which is, of course, reflected in concrete costs for the operator.

TBH’s CR series mobile extraction systems demonstrate their specific benefits in this deployment area. A total of four basic devices can be adapted and/or upgraded modularly to the respective clean room class and the concrete application. The modular device concept also makes contamination-free filter changes easier and thus offers the necessary security for operators, employees and the workroom environment. The exhausted filter is passed out completely via transfer liner and a new filter block is passed in.

The separation of the filter block from the extraction system mounting bracket is the most critical point here but is uncomplicated due to a special design and procedure for CR series devices. The encapsulated filter blocks contain a suction tube and an extendable protective hose. When the suction tube is disconnected from the mounting bracket pipe, the protective hose can extend a little and the disconnection point is bridged. This permits the protective hose to be crimped over the open air intake with a special tool so that is airtight. This means that the filter cassette air intake and the pipe on the mounting bracket are still dustproof and shielded from the environment. The crimping point is then cut off centrically with the cutting tool.

The protective hose of the new filter block is now pulled over the mounting bracket pipe and fixed in place. The remaining sealed hose can be pulled off the mounting bracket pipe by means of an insert in the transfer liner; this remains in the new filter’s connector. This procedure ensures that no particles from the used and replaced filter block get into the ambient air to roam around in the clean room.

As with all extraction and filtration systems, TBH GmbH also places great value on the quality and reliability of CR series systems. The systems also set themselves apart from other products offered on the market with their compact shape, a motor suitable for continuous operation, comprehensive control options, etc.

TBH Extraction and Filter Systems, ATEX Series

In Europe, occupational health and safety at the workplace is becoming increasingly important. At the same time, production processes are becoming increasingly complex and particle sizes are becoming smaller and smaller. All these factors have resulted in a rising demand for extraction and filter technology that not only reliably protects systems and worker’s health, but also takes changing process parameters into account. Standards are extremely high, particularly in ATEX areas, where explosive air/dust mixtures can develop. Different factors, such as the required air flow rate, filter size, process integration, safety regulations and zone classification, etc. all have to be taken into account.

TBH GmbH offers different ATEX compliant extraction and filter systems for such applications. Among other things, the two different sizes offered in the FP series cover a wide range of potential customer applications. The FP 150 ATEX system, based on the existing FP 150 system, is equipped with a cleanable cartridge filter meaning that built-up dust on the filter can be removed using bursts of compressed air, which in turn considerably increases the service life of the system. Various design features, as well as a special ATEX-tested particle filter (filter class H13 in accordance with DIN EN 1822) contribute to the system’s safety. This extraction and filter system is used in areas with a required extraction volume of approx. 250m³/h and has a maximum vacuum level of 21000 Pa. This makes it optimal for extracting particles and emissions even in narrow intake areas and with longer suction lines.

FP 211 ATEX or FP 213 ATEX extraction and filter systems are used in applications with multiple extraction sites and/or large amounts of dust. Both systems, as opposed to the FP 150 ATEX, have six instead of just one cleanable filter cartridge. The FP 211 ATEX with an air flow rate of approx. 1500 m³/h and max. 3000 Pa, or the FP 213 ATEX with an air flow rate of approx. 800 m³/h and max. 15000 Pa are used according to application requirements (intake area, suction line length). They are particularly suited for larger machining processes and offer a longer service life. Thanks to various design modifications and adjustments, as well as a special ATEX particle filter (filter class H13 in accordance with DIN EN 1822), systems from the FP 200 ATEX series also meet ATEX requirements. Cleaned air can subsequently be diverted back to the processing area without any problems. Heating costs can also be saved in this way.

The systems were designed and constructed in accordance with the ATEX Directive (94/9 EC ATEX Product Directive) and documentation has been presented to a notified body (IbexU) in accordance with the Directive. In order to allow for easy integration into the overall system and to simplify operation, the systems are not only equipped with a filter monitoring mechanism (differential pressure), but also feature fully adjustable speed control and malfunction indicators. The interface with a start/stop function, a change-filter signal and external speed control allows customers to monitor the entire system for error messages. This means users can simply integrate the extraction and filter system into their processes, and, depending on the manufacturer, use this system to control extraction and filtration.

As with all extraction and filter systems, TBH GmbH’s top priorities for the ATEX series are the quality and reliability of the systems. The systems’ compact design, motor designed for continuous operation, extensive control options and numerous other features set them apart from competing products on the market.

Safety through a spark trap and an automatic CO₂ extinguishing system

Solid state lasers have become the norm for welding and cutting tasks. They make welding without shielding gas possible in many situations. Generally, it is the workpiece that moves and the laser remains in a stationary position. This arrangement ensures efficient fume extraction directly at the point of origin using source extraction.

Large demands are placed on automated production processes in terms of quality, operational safety and reliability; at the same time it is expected that costs are kept to a minimum. The mobile source exhaust and filtration unit FP150/CO2 from TBH meets these requirements. The exhaust and filtration unit protects both humans and the machine, and enables the extraction of welding fumes as well as flying sparks directly at the source.

The development engineers at TBH have fitted the unit with a number of safety devices to ensure that the filter system does not fail or become damaged in the event of a fire. A generously sized spark trap that acts as a pre-separator prevents smouldering particles form getting into the actual filter system. Moreover, the system is equipped with a fully automatic CO2 extinguishing system which can safely interrupt the process. Meaning, for example, that it optimally meets the safety requirements of well-known automotive manufacturers. If required, the unit can also optionally be connected to the fire alarm control centre of the plant fire brigade.

To keep the air clean, the extraction system FP150/CO2 has a 2-stage filter configuration with a backwashable cartridge filter, with an H13 or H14 HEPA filter with a separation efficiency of 99.995% (DIN EN 1822), and an exhaust air connection piece to the outside. As a whole, the system has a modular and easy to maintain design. Maintenance work can either be performed quickly on site or, thanks to its mobile design, the extraction system can also be taken to a service or maintenance department for maintenance.

As with all extraction and filter systems, TBH GmbH’s top priorities for the FP150/CO2 are the quality and reliability of the system. The system’s compact design, motor designed for continuous operation, extensive control options and numerous other features set it apart from competing products on the market.

TBH OEN Series ofExtraction and Filter Units

Alongside a wide range of extraction and filter units in the field of laser processing, TBH GmbH also offers tailor-made systems for classic machining processes such as turning, milling, drilling, and sanding. In order to prevent consequential damage to machinery and employee health issues, the particles that are created by these processes, as well as oil mist and oil emulsion mist that are created when liquid coolants are used, must be reliably extracted and the contaminated air must be filtered.

The OEN series of systems is used to extract the oil mist and oil emulsion mist that is created in machining processes. These systems are available in two versions. The optimal system can be selected based on how high the particle count is and how much oil mist is released by the individual application. The OEN150 and OEN170 systems are especially suited for situations with a lot of particulate matter and a lower aerosol percentage in the process air. Different filter stages with saturation filters are used for these applications. This makes it possible to extract both particles and aerosols from the machining process. The system first separates the aerosols using an aluminium mesh filter and then transports the contaminated air to a pre-filter (F7) and a downstream particle filter (H13).

In the OEN155 system, a special filter cartridge is used, which differentiates it from the two systems previously described. This filter cartridge makes it possible to extract large amounts of oil mist when there are few particles in the process air. In the first step, the air goes through a special filter cartridge (F9), which separates larger particles from the overall moisture in the air. Next the process air goes through a particle filter (H13), which removes the fine particles.

Depending on the application and required air flow, you can select from either a special high-power turbine that generates a powerful vacuum (20 kPa) and an air flow rate of 250 m³/h (OEN150 and OEN155) or a fan with a vacuum of 3 kPa and an air flow of 1500 m³/h (OEN170).

In order to allow for easy integration into the overall system and simplify operation, the system is not only equipped with a filter monitoring mechanism (differential pressure), but also features fully adjustable speed control and malfunction indicators. The interface with a start/stop function, a change-filter signal and external speed control allows customers to monitor the entire system for error messages. This means users can simply connect the extraction and filter system to their own machining equipment, and, depending on the manufacturer, use these systems to control extraction and filtration.

As with all extraction and filter systems, TBH GmbH’s top priorities for the OEN series are the quality and reliability of the systems. The systems’ compact design, motor designed for continuous operation, extensive control options and numerous other features set them apart from competing products on the market.

TBH FP 150 ATEX Extraction and Filter System

Just as the laser processing market is continuing to grow and present new challenges, TBH GmbH is expanding to many new areas, including ATEX applications. Extracting highly flammable and explosive substances places high demands on a system’s design and safety functions.

TBH’s new series, whose first product is the FP 150 ATEX extraction and filter system, enables customers to extract directly from atmospheres with zone-21 levels of explosive dust. Critical dusts up to a minimum ignition energy of >3 mJ can be reliably filtered out thanks to universal ignition prevention throughout the entire system. Both the special earthing concept and an additional level of safety that reliably separates the extracted dust particles from the system electronics help prevent ignition.

The FP 150 ATEX (see Fig. 1 for the product labelling) is based on the technical concept of the FP 150 filter cartridge system. It features a filter cartridge (dust class M) that can be cleaned using bursts of compressed air. This constant cleaning ensures a long filter service life. The system also uses a special particle filter (filter class H13) that further increases the separation efficiency and adds a level of safety for the system electronics.

The use of a special high-power turbine that generates a powerful 20 kPa vacuum, as well as an air flow rate of 250 m³/h, ensures reliable extraction even with small intake areas.

In order to allow easy integration into the overall system and simplify operation, the system is not only equipped with a filter monitoring mechanism (differential pressure) combined with automatic filter cleaning, but also features fully adjustable speed control and malfunction indicators. The interface with a start/stop function, a change-filter signal and external speed control allows customers to monitor the entire system for error messages. This means users can simply connect the extraction and filter system to their own systems, and, depending on the manufacturer, use these systems to control extraction and filtration.

As with all extraction and filter systems, TBH GmbH’s top priorities for the FP 150 ATEX are the quality and reliability of the system. This system’s compact design, motor designed for continuous operation, extensive control options and numerous other features set it apart from competing products on the market.

TBH Extraction and Filter Units

Rapid technological advancements and increased competition are forcing companies today to switch their production processes quickly and flexibly. In order to ensure this flexibility, TBH GmbH offers modular extraction and filter systems. The modular design makes it possible for TBH GmbH to provide solutions for a wide range of applications. Multiple filter stages, connected in series, and high-quality motors ensure optimal filtering of particles, vapours and waste products of all kinds.

All TBH extraction and filter systems are designed and developed to be modular. The motor module (5), which forms the basis of the devices, is selected according to customer requirements. The motors used here are available with a suction output of 100 to 2000 m3/h, which covers a wide range of applications. The modular design makes maintaining the devices extremely easy, since only the motor module needs to be sent to the manufacturer for analysis and maintenance.

Various filter modules follow the motor module. They are supplied with different filters based on the customer’s application. This guarantees that the extraction and filter system is completely adapted to the manufacturing process. An additional benefit of the modular system is that it is easy to change the filter. The pre-filter (2), main filter (3) and active carbon filter (4) can be replaced individually. Since single filters are used instead of  combination filters, the cost of changing filters is also reduced.

The systems are rounded out by a cover (1). The wide variety of connection options in the cover, with nominal widths for the most frequently used cable cross sections (NW 50/80/100/125 mm) and the reduction option, make it possible to connect various collection elements and suction hoses.

TBH-CR series of extraction systems

Clean rooms are essential to meeting today’s constantly increasing standards of quality. What used to vary from industry to industry and region to region is now specified in the EN ISO 14644-1 standard with its clearly defined ISO clean room classes. The different classes are based on the amount of airborne particles permitted in the clean room.

Clean rooms are used in the production of microelectronics, in laboratories, in the food and beverage industry, and in many other sectors. TBH has been doing business in this field for many years and offers a broad range of extraction systems for a wide variety of processes in the ISO classes 3, 5, 7 and 9. Thanks to TBH’s popular modular design concept, the CR series offers features such as contamination-free filter replacement right in the clean room.

The series also offers advantages such as a variety of filter configurations, including the Z filter package with a large Z-line panel filter (F7) as a pre-filter and a downstream particulate matter filter (H14 HEPA filter). This package is used for applications with high fine dust emission levels. The A filter package is for use in clean room processes in which vapours or gaseous molecules are produced. It includes both an activated carbon filter and a downstream particulate matter filter. Depending on customer requirements, an additional “police filter” (an H13 particulate matter filter) can also be mounted on the exhaust panel.

Regardless of the filter configuration, the CR series also comes in a variety of models, including: CR-LN 230, CR-LN 265 or CR-GL 230 and CR-GL 265. Each of these CR systems is continuously variable. The main differences between them are their extraction power levels and their filter areas. All CR devices from TBH are made of stainless steel to allow easy cleaning and ensure fulfilment of additional standards of quality.

BF 5 and BF 10 extraction systems

The new BF 5 and BF 10 extraction systems from TBH GmbH represent a practical addition to their product range of small, compact systems. Typical applications for these compact extraction systems include laser processing in laser systems with lower power levels (engraving, inscription), soldering and bonding, and other applications that require a small, but quiet extraction system.

These extraction systems feature self-explanatory operation and simple filter changing, which distinguishes them from other systems on the market. The systems are very compact (315 or 510 mm x 300 mm x 300 mm) and can blend into almost any workplace. The pleasantly low noise level means that the systems can be located within the working space without bothering the workers.

Like most of the systems from TBH, both extraction systems have a control knob on the front of the unit, which is used to adjust the power. They are also equipped with a real-time operating hour meter and filter differential pressure monitoring, which activates an LED on the front of the unit to indicate exactly when the filter needs to be changed. The extraction systems can also be switched on and off externally via the interface. This interface can also be used to signal when the filter has to be changed.

These extraction systems use a special composite filter with an activated carbon level and an H13 fine particle filter. The BF 10 system is also equipped with an F5 grade prefilter mat.

Thanks to the quiet, maintenance-free motor, BF 5 and 10 extraction systems are also suitable for continuous operation. Unlike other inexpensive extraction systems on the market, costly repairs and production downtime due to worn out motor carbon brushes are not a problem. The systems require extremely low input power of 40 or 200 W with extraction power of up to 100 or 200 m³/h.

As with all TBH extraction and filter systems, a lot of emphasis is placed on following the EMC guidelines and safety guidelines in order to ensure safe operation without faults or errors. The extensive range of accessories offers a number of practical additions to the extraction systems, including suction arms, hoods and hoses.

FPV-180 pre-separator

Pre-separators, which are installed upstream of extraction and filter systems, may be practical or necessary in some applications. These devices pre-separate large and medium-sized particles, which increases filter service life and reduces process costs. With its new FPV-180, TBH GmbH now has a passive pre-separator with cleanable filter cartridges which is designed for medium amounts of dust and flow rates. This device can be used to pre-separate a wide range of dust types, with precoating for sticky and moist dust. In combination with the LN and GL series external extraction and filter systems and the new precoating system from TBH, we have a new extraction system that can be easily integrated into the user’s automation process. It is particularly suitable for 24/7 processes (such as laser processes) for use in workshops and laboratories.

The new, intelligent device control makes it much easier for the user to operate and install the units. Cleaning can be performed manually, or automatically with pulses of compressed air. The user has a choice of different operating modes, such as differential pressure-controlled cleaning, interval-controlled cleaning, coastdown cleaning and manual cleaning. This means that the user can choose the cleaning method that best meets the individual requirements of the application. An integrated stop valve and the shut-off valve control prevent the cleaning pulse from disrupting the process. An integrated interface allows you to connect several pre-separators in parallel that are individually cleaned and closed off from the system, which makes it possible to design redundant extraction and filter systems.

Extraction and filter unit

Manufacturing modern artificial limbs and orthotics and providing them to patients and rehabilitants represents an important subarea of medical aftercare. These products are individually produced and repaired in orthopedic rehabilitation workshops, which are microenterprises that can also be directly connected to clinics and hospitals.

Today various raw materials are used to produce orthopedic products: wood, steel and leather, but also modern materials like plastics, cast resin and carbon. While working and processing the materials in these workshops and work areas, the employees' health can be harmed by dust and gas emissions. In particular, these emissions consist of micrometer-sized fine dust particles that are alveolar and enter the body through the respiratory system, where they can impair or damage your health. It is therefore essential to effectively eliminate these types of emissions in the workplace.

Since 1992, TBH GmbH in Straubenhardt has concerned itself with creating healthy workplace conditions that are free of dust and harmful gases. Their portfolio includes a number of mobile devices and systems that are used to extract and filter contaminant-laden air. The company offers compact LN and BF series filter units, which are particularly suitable for use in orthopedic workshops. These units are equipped with multi-level filter systems and practical accessories, which can be easily and conveniently operated and maintained. The device concept is based on a modular design. This allows the user to enhance an existing and fully functioning base unit with additional filter modules according to the type of contaminants that need to be extracted. All TBH units are equipped with a fully adjustable power control and a dependable monitoring system for the filter load.

With its “Compair” extraction and filter unit, TBH offers a suitable solution for very small workshops with a minimum of utility space. The extremely compact size of 290 mm x 290 mm x 560 mm (L x W x H), the integrated composite filter and the extraction power of 120 m³/h make this unit an effective and affordable all-rounder in the workshop. In addition, practical and compatible accessories – such as suction arms, hoods, nozzles and hoses – are available for all TBH extraction and filter systems.

The downdraft table is also suitable for use in workshops, e.g. in spray-painting work (such as spot repairs) and gluing processes (solvents). In order to comply with workplace requirements for these sectors, the downdraft table was developed in accordance with ATEX guidelines and is suitable for zones 22 (dust) and 2 (gas), which means that it complies with ATEX category EX II 3GD.

Compact, with dimensions of 1800 mm x 800 mm x 680 mm (H x W x D), the cabinet also has other specific product characteristics. With its integrated height adjustmentfeature, working height is infinitely adjustable within a range of 850 to 950 mm. The protective screen, which is height-adjustable in 50 mm stages, also allows optimum application-oriented workstation configuration. As an optional extra, it is available with a factory-fitted foot switch, to improve user-friendliness even further. To allow you to monitor the saturation filters, the unit has a differential pressure indicator positioned on the front side. As with the majority of TBH filtration units, the downdraft table is multilevel in design and comes with a pre-filter (F5) as standard. Depending on the application, the downdraft table can be fitted with a particle filter /HEPA filter (H13) to remove the finest dust particles, and a gas filter (activated carbon/BAC).

An all-rounder – filter cartridge unit for fine dust

Once again, a modular design was the key focus of the latest product development from TBH GmbH. This allows the new FP210-215 filter cartridge unit to be adjusted and configured according to each application exactly – a true all- rounder that helps save space, energy and costs. It can be deployed to filter fine dust particles (e.g. laser emissions, welding fumes and grinding dust) in precision engineering and processing.

The filter cartridge units are available in two extraction classes of 800 m3/h and 1500 m3/h. The extraction level can be set and controlled both manually and using an interface. Depending on the application, 2 or 6 filter cartridges with different filter surfaces can be used. These are equipped with a high-quality microfibre surface. This surface ensures long service life and efficient particle extraction. Regardless of the application, there are two filter cleaning processes to choose from: interval cleaning or coastdown cleaning. The filters are cleaned with compressed air. Thanks to the modular design, the units can be optionally equipped with an activated carbon and a particle filter. The optional particle filter, also known as a police filter, increases the separation efficiency of the entire system from H10/11 to H13 (separation efficiency 99.95% in accordance with DIN EN 1822). The most important main functions of the filter cartridge units can be monitored and fully controlled using a serial SUB-D interface.

Extraction technology for clean rooms and clean room areas

Ever greater quality requirements, the increasing miniaturisation of components and products and increasingly complex production processes have driven the development of clean room technology. TBH faced these challenges and, with the help of end users, developed the new, usage-based extraction and filter units of the TB-CR series. The unit design complies with the DIN EN ISO 14644-1 standard for clean rooms and clean room areas, and, depending on the level of extension, provides the option of carrying out different qualification measurements (fit test, particle measurement). Compliance with the standard and ISO classes has been confirmed by CCI (Contamination Control Instruments) in Stuttgart.

Therefore, the new extraction and filter units of the CR series, depending on the extension level, can be deployed in clean rooms of ISO classes 3, 5, 7 and 9. Thanks to the modular unit structure, the filter can be changed easily with no risk of contamination. The CR series is offered with air flows of 280, 330 and 440 m3/h. Users can choose the filter equipment. The ZH filter package, which consists of a Z-line pre-filter (F5) and a downstream HEPA filter (H14), is suitable for extracting fine dust emissions. The A filter package with activated carbon and a downstream HEPA filter (H14) is offered for extracting fumes and gases.

Space-saving extraction and filter unit for small laser units

Laser processing, laser welding, cutting, engraving and marking produces emissions that are hazardous to health. Consequently, there are legal regulations on the maximum concentrations of these contaminants in the workplace. These requirements can be met with extraction and filter systems with the appropriate performance levels.

The compact GL30 extraction and filter unit by TBH is designed as a substructional unit especially for small laser devices. This allows the laser to be placed on top, so that installation together with the extraction and filter unit is possible even in the most confined spaces. In spite of its compact dimensions of 700 mm x 710 mm x 700 mm (H x W x D), very large filter surfaces are achieved with the use of new filter designs. The “MP-TEC” pre-filter has a filter surface of over 9 m2. This leads to a long filter service life and consequently optimizes operating costs. Energy-saving designs are also becoming increasingly important in investment decisions. The GL30 extraction and filter unit has an effective air flow of 440 m3/h but a power consumption of only 0.36 kW. That means: unchanged performance with low energy costs. The unit is equipped with powerful electronics. The standard version has infinitely variable speed control with visual and acoustic filter status indicators, as well as an integrated SUB-D interface to control and monitor the most important functions externally.

Proven extraction technology with significantly less energy consumption

The technical requirements for modern extraction and filter systems used for materials processing are today defined by legal regulations on workplace ergonomics and occupational safety. With all the discussions surrounding high CO2 emissions, demand for more energy-saving concepts have, quite rightly, increased. TBH faced these challenges and with its new GREENLINE GL series and offers a device family that not only meets legal requirements for occupational safety, but also requirements for low energy consumption.

Assuming that electricity costs 0.27 € per kWh, a conventional extraction device with an air flow of 280 m3/h and a power consumption of 1.1 kW will incur energy costs of 2.38 € when operated for eight hours. At first glance, this may seem to be an acceptable amount. However, over the period of 220 working days per year, this amount increases to 523 €. With the GL230 and GL265 extraction and filter units from the GREENLINE series, TBH is bringing two compact systems to market. If the same cost calculation is applied to the new GL230, for example, with its greater air flow of 330 m3/h and lower power consumption of 0.24 kW, annual power costs are reduced to only 114 €.

This amounts to an annual cost saving of 409 €. With a double or triple shift operation, total savings can even amount to between 800 € and 1200 € per year.
