The blower and EC-filter is an under- and over-pressure filter, designed for continuous operation.Constructed as a self-supporting sheet metal construction. The round design ensures great strength combined with low weight.
Surface
Powder coated to corrosion class C3 cf. ISO 12944.
Inlet
The Blower and Jet filters are fitted with 180º tangential inlets to ensure effective sorting of heavy materials before the process air passes through the filter medium.
BF-34, 36, 55, 60, 84 and 90-filters are also available with total separators. Standard height is 1000 mm, with the inlet at 90ºC. This type of inlet is used in plants in which the process air contains heavy and sharp articles to prevent them coming into contact with the filter medium.
Cleaning system
BF-36, 60 and 84/90-ET filters are available with PowerPulse® or Blower cleaning. BF-8, 12, 20, 34 and 55-filters are supplied with EC-cleaning.
Discharge system
Conical or scraper bottoms are available for the discharge system, but silo filter is also available.
ATEX
BF-36, 60 and 84/90-ET with PowerPulse® cleaning, external compressed air or internal compressor are equipped with approved explosion membranes. Choose between side venting or JKF’s specially developed VFV® explosion relief venting, which vents explosion pressure vertically through the filter top. The filters fulfil pressure shock-resistance according to VDI 2263. Venting according to VDI 3673.
