FAQs on filter bags from BWF Envirotec:

A filter bag is filtration technology for filtering dust in a baghouse. It separates dust, harmful substances and also products from gas flows.

With over 50 years of experience, BWF Envirotec is the leading manufacturer of filter media and filter bags for dedusting processes in the processing industry.

Filter bags consist of needle felt or fabrics made of synthetic fibres. The needle felt is optimally adjusted for the application case at hand.

Filter bags are used for dust removal processes and for filtering waste gas and exhaust air in industrial plants. They make it possible to comply with the legal limits for (fine) dust emission and thus ensure clean air.

The internal support fabric gives the filter bag additional strength that makes both frequent bag cleaning and a long service life possible.
