Filtriseade Blower
Blower and Jet filters
The blower and Jet 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.
Blower and Jet 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. JF-9 and JF-18-filters are supplied with Jet or Blower 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 and external compressed air have 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. The Jet filter with external compressed air source is supplied ATEX-approved.
