Large-area filters are used in all modern Brückner bi-axial stretching systems. Over the past years, Brückner Servtec has conducted very successful replacement installations or enhancements in melt filtration for various customers around the world, whereby special and customer-oriented filters - disk and candle filters - have been installed.
The filter systems are available for PP, PET and PA films. Duplex filter systems ensure often a film production at highest quality. The offered filter areas cover an output range up to 9,500 kg/h for PP film and 6,000 kg/h for optical PET film.
Single-screw extruders, special melt filters, pumps and melt pipes that can be found in many of Brückner Maschinenbau’s film stretching lines and in Brückner Servtec’s upgrading projects all come from BB Engineering.
