INFA-MICRON MKR
Cassette filter for dedusting of sophisticated processes where toxic dusts or powders, e.g. API (active pharmaceutical ingredient)
Highlights
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
