Our company
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, 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 from coming into contact with the filter medium.
Cleaning system BF-36, 60, 90 ET filters are supplied with PowerPulse®. BF-8, 12, 20, 34, 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.
