High product quality and availability

Whether you are processing polyamides, terephthalic acid (PTA), aramids, polymers, bisphenol or other plastic intermediate products: Continuously operating high-performance filters deliver high product quality due to the excellent washout quality they provide. The filters have a long service life, are built for robust use and ensure economical plant operation thanks to the low maintenance and energy costs they incur. Operating temperatures of up to 160 °C with the rotary pressure filter and filter surfaces of up to 100 square meters with the indexing belt filter go a long way toward ensuring efficient production.
