BWF Envirotec is the leading provider of filter media for industrial filtration and solid/liquid separation with manufacturing sites throughout the world. It produces over nine million ready-to-install filter media annually under the brand names needlona® and PM-Tec® . as well as Pyrotex® KE filter elements for hot gas filtration.

Some of the chief areas where its needlefelt and glass fabric filter media and filter elements are employed are in biomass or coal-fired power stations, in the chemical and pharmaceutical industry and in asphalt, steel and cement plants.

Of specific interest to BWF Envirotec in selecting the new Montex 8500TT stenter was its ability to thermally set PTFE fabrics without oil greasing in the stenter chain and in the width adjustment.

“This protects workers and the environment from harmful oil vapours and keeps the filter material clean,” explained Jürgen Hanel, Monforts Head of Technical Textiles.

“The guarantee of reaching 320°C with a very low temperature tolerance and with an excellent housing insulation is a major advantage, so that an outside temperature over 60°C is never reached at any position.”
