Steel and metal industry
BWF Envirotec filter technology

In the steel and metal industry, reliably reducing emissions is a central task in filter technology. Every manufacturing process places individual demands on filter media and industrial filters.

High filter surface loads or different harmful gas compositions are only some of the requirements for the filter medium that play a major role in filter technology. Here at BWF Envirotec, we design industrial filters for every filter technology application tailored exactly to your application. Our industrial filters distinguish themselves with their excellent filtration properties and long service lives.

Our best filters for the steel and metal industry

needlona® (specially developed filters made of needle felt filter media) and PM-Tec® industrial filters (ePTFE membrane industrial filters made of needle felt filter media or glass fibre for fine dust filtration) offer optimum filtration results for abrasion resistance, resistance to occasional sparking and pyrophoric dust, hydrolysis resistance and fine dust separation.

Our industrial filters are used in the production of zinc, steel, aluminium, lead and copper.

Our application technology engineers offer highly efficient, best-case solutions for filter technology. We aim to help our customers set standards and achieve high performance goals. To this end, we offer a complete range of including installation, commissioning, maintenance and repairs and filter system optimisation.
