Technology

The cassette filter system INFA-MICRON MKR is available as cleanable dust collector with one or two filter stages as well as non-cleanable, downstream safety filter. The filter sizes cover air volume ranges of > 500 m³/h.

Big volume flows can be cleaned by parallel arrangement of several units. The 2-stage design guarantees residual dust contents as low as 0.001 mg/m³. Filter cassettes of class H13 are used as filter media for the cleanable 1st stage and H13 to U15 for the non-cleanable 2nd stage.

Standard design features

• Cleanable cassette filter in modular design for flexible adaptions to individual requirements with one or two filter stages
• Change of filter cassettes on the clean gas side
• Filter housing made of mild steel S235JR with hopper and dust discharge system respectively dust collection equipment
• Pneumatic cleaning device with movable nozzle arm (backflush system) for cassettes of the 1st filter stage
• Standard +/- 50 mbar and up to 80 °C, optional 250 mbar and 150 °C
• SPS control unit for filter cleaning triggered by time cycle or differential pressure incl. control of nozzle arm and shut-off valve, surveillance of single operating conditions by proximity switches and indication by plain-text display
• Use of particulate filter cassettes of filter class H13, tested according to DIN EN 1822
• 2nd filter stage (not cleanable) of filter class E10 or higher as safety filter respectively "back up filter", according to DIN EN 1822
• Filter cassettes in compact design with MDF-frame allow easy handling and thermal waste treatment (hazardous-waste incineration)
• Leak-proof test device for every filter cassette
• Minimum shutdown time as well as low operating and maintenance costs because of high reliability and easy handling
• Cleanable filters with pneumatical clamping device respecitively manual clamping device for non-cleanable filters
• Inspection window after the first filter stage for function check of the filter
• Gas tight by welded and strengthened filter housing for pressures (as standard the non-cleanable series is screwed)
