HERR Industry System uses a variety of filter cartridges for the purification of cutting and welding exhausts. The cartridge systems can be automatically cleaned. They incorporate the use of the HiRoto® H-type rotary backflush nozzle.
The HiRoto® H rotary back flush nozzle and the HISTec® ePTFE laminated filter cartridge are the perfect combination of a high efficiency filter cartridge and cleaning device. They can easily handle any heavy dust workload, from a variety of sources including CNC plasma cutting, and CNC laser cutting.

The filter system initiates the cleaning process when an internal pressure sensor measures a change in the pressure differential between the inside and outside of the cartridge. This instructs the system that dust has accumulated on the outside of the filter cartridge and to initiate a cleaning process. After cleaning, the dust falls to the bottom of the collection box. The filtered air is clean and can be returned inside the factory. Cartridge exhaust syestems use the same ePTFE filter cartridge as our central exhaust systems. Filter life is upwards to 3 to 5 years.
