About KÖGEL FILTER
KÖGEL FILTER GmbH is a specialist in process filtration and the converting of filters for solid-liquid separation and gas filtration. The company manufactures filter cloths for nutsche filters, centrifuges, plate-and-frame and belt filters, filter hoses/socks for candle filters and industrial dust extraction, filter elements for fluidized bed drying, PTFE membrane filters for laboratory filtration, and the LYOSAFE® system for freeze drying. Production has been carried out entirely under ISO 7 cleanroom conditions in Landau (Pfalz) since April 2020. Filter cloths and hoses are cut using laser and ultrasonic technology; welding processes (hot air, heated wedge, tubing line) frequently replace sewing techniques. The materials processed are synthetic media made of PP, PEEK, PTFE, ePTFE, PET, PA, PPS, ECTFE, ETFE, aramid and PI as well as stainless steel. Products are manufactured for customers from the pharmaceutical, chemical, food and animal feed industries, as well as lime works, incineration plants and power generation. For the pharmaceutical sector, only EU- and FDA-compliant media are used.
