The FP 150 ATEX is equipped with a cleanable anti-static filter cartridge which allows dust build-up to be removed from the filter using bursts of compressed air. This means that the device is ideal for applications in which large amounts of dry, flammable dust with a minimum ignition energy of > 3 mJ are extracted, and that it has a very long service life in comparison to systems with saturation filters.
The system meets the requirements of the ATEX directive (EX II 2/- Dc IIIC T100oC) and is suitable for extraction from a zone 21, although the system must be placed outside of the zone. The suitability for the respective application depends on the substance to be extracted and must be considered individually. In appropriate situations, use for a minimum ignition energy of < 3 mJ can also be checked.
The contaminated air, which consists of flammable dusts, is collected by the collection unit (extractor hood, suction arm, hose, etc.) and transported into the filter unit directly or through an earthed pipe or flexible hose. The dust particles are filtered out by a cleanable anti-static filter cartridge in the filter unit. The filter cartridge is cleaned using an automatic cleaning system. The automatic cleaning system is triggered by the system’s differential pressure controls whenever the extraction level decreases. The filtered-out dust particles are collected in a dust collector for easy disposal. If necessary, a dust bag can also be inserted for low-contamination disposal. The cleaned air is then passed through a particle filter (which represents another level of safety) and – depending on the application – transported back into the work area or diverted outdoo
