JKF DustStorm - Under and Over-pressure Filter

Surface

Powder coated to corrosion class C3 cf. ISO 12944.
 
Inlet

Contaminated air passes into the filter through the pressure loss optimised inlet, ensuring optimised separation of the dust particles.

DS-12, 20, 28, 36 and 44 are supplied with side inlet according to the "partial downflow" principle. A diffuser effect which ensures minimum pressure loss with maximum effect. Alternatively, the filters can be fitted with a total separator. DS-7 and 12 are supplied with total separators.
 
Cleaning system

DS-12, 20, 28, 36, 44 has the PowerPulse cleaning system with filter control system ECOTROL or DS total cleaning system. DS-7 EC and DS-12 EC have EC cleaning.
 
Discharge system

DustStorm filter is available with conical or scraper bottom. The DS filter is also available as a silo filter. DS-7 is only available with conical bottom.
 
ATEX

DustStorm filter is fitted with approved explosion membranes with side relief venting. The filters fulfil pressure shock-resistance according to VDI 2263. Venting according to VDI 3673. The DS filter with external compressed air source is supplied ATEX-approved.
