The filter unit is suitable for filtration of dry dusty air types, where ATEX-equipment is needed. Filter unit can be equipped with output systems for containers, bulk bags or the like.
Inlet with downflow and pre-separation as well as optimized filter cleaning ensure lower differential pressure above the filter cartridge. Therefore longer operation times with less shutdowns as well as lower operating costs (filter materials, electricity and compressed-air consumption) are achieved. One-cone version, which minimizes unit costs in connection with waste management.
Filter unit is delivered in two modules that are assembled on the installation site by external flanges. Filter cartridges and control are delivered mounted. Compressed-air connection is easily connected on unit front. Easily accessible reading of differential pressure in digital display of filter control placed on unit service side. Filters are replaced through front door in unit side. Quicklock-adjustable dust container on 4 turnable wheels ensures user-friendly dust container service.

Material
Membrane: AISI 304
Mating flange: Galvanized
Relief pressure: +0.1bar
Relief area is calculated for the individual unit for Kst = 300bar m/sec and Pmax = 10bar
Relief membrane is designed as a single unit, which provides a light construction and thus fast opening. The membrane is especially developed for dust explosion relief and gives a reliable ensurance, since it relieves at an early stage, already in the start of an explosion..
NOTE
At installation of units with relief membrane you must be aware of the heavy pressure wave and the flame spread that will occur in areas outside of the relief membrane and mount the unit so that the explosion is led away from people and building components..
Jet filter type QFG-A is constructed according to:
Filter cabinet is made in 2mm black steel plate
Surface powder enamelled RAL 5007/7011 structure
*Please note: Unit height is increased by 330mm
Jet filter filter type QFG-A is available in the sizes as stated in the form below.
Please, contact us for assistance in selecting the optimal unit taking into consideration air volume, dust type and volume, operation times etc.
