TBH Suction and Filter System FP 150 ATEX

Alongside the continuously growing market of laser processing with ever new challenges, TBH GmbH also offers solutions for many other application areas such as ATEX applications. The extraction of easily flammable and explosive substances places high demands on system design and safety considerations.

With a new series of systems, whose first product is the extraction and filtration system FP 150 ATEX, the company now provides customers the opportunity to directly extract from a dust explosion zone 21. This allows critical dusts with a minimum ignition energy of >3mJ to be reliably separated. This is achieved through continuous prevention of sparks throughout the system. Both a special grounding concept and an additional safety level, which reliably separates the extracted dust particles from the system electronics, contribute to this.

Technically, the extraction and filtration system FP 150 ATEX (see Fig. 1) is based on the concept of the FP 150 filter cartridge system. It features a filter cartridge (dust class M) that can be cleaned by compressed air pulses, enabling a high filter lifespan through continuous cleaning. Additionally, a special particle filter (filter class H13) is used, which further increases the separation efficiency of the system and serves as a safety level for the system electronics.

By using a special high-performance turbine and the resulting high vacuum of 20 kPa, along with an air volume of 250 m³/h, it is possible to reliably extract even with small suction cross-sections.

To enable easy integration into the overall system and simplify operation, the system is equipped not only with filter monitoring (differential pressure) and an automatic filter cleaning linked to it, but also with stepless speed control and fault indicators. An interface with start/stop function, filter change signal, and external speed control also allows the customer to fully monitor all possible error messages. This makes it possible for the user to easily connect the extraction and filtration system to their system and operate it depending on the manufacturer.

As with all extraction and filtration systems, TBH GmbH places great importance on the quality and reliability of the systems with the FP 150 ATEX. The system also stands out due to its compact design, a motor suitable for continuous operation, extensive control options, and more, clearly differentiating it from other products offered on the market.
