BWF Envirotec Is Extending Its Product Portfolio with The Pm-Tec Membrane Product Line

German company BWF Envirotec is extending its product portfolio with the PM-Tec membrane product line for industrial air filtration.

BWF Envirotec says that the new product line combines carrier media consisting of needlona® needle felt or fibreglass fabric with a high-efficiency ePTFE membrane. The continuous in-house process chain starts with the manufacture of needlona® filter media, includes the laminating process, and finishes with complete filter bags.

The PM-Tec filter medium with an ePTFE membrane offers extremely low emissions. The product line consists of a carrier medium on which an ePTFE membrane is laminated. The membrane produced from polytetrafluorethylene possesses characteristics that are particularly suited for use in industrial fine dust filtration.

Dust on the raw gas side impinges on the filter medium that is already retained on the surface and cannot penetrate into the carrier medium. Owing to the smooth and anti-adhesive surface, the particles do not embed themselves in the carrier medium but accumulate on the surface of the filter medium instead and are almost completely cleaned away during the dedusting process in the filtration system.

BWF Envirotec adds that the membrane structure is characterised by optimum orientation and fineness of the fibrils, as well as a uniform pore size. A low surface tension which reduces the adhesion of fine dusts, as well as a temperature resistance of up to 288°C, optimises filtration properties. During the production process, BWF Envirotec has added in-line quality controls and constant air permeability monitoring during the laminating process. Demanding emission requirements can be met through appropriate sewing and sealing technology during the manufacturing process.

Extremely low and stable differential pressure behaviour, constant gas volumetric flow, long service lives, low maintenance expenditure and high reliability are further characteristics of the PM-Tec product line from BWF Envirotec.
