Manufacturer of industrial filtration products from Bavaria
Filtertechnik Jäger GmbH is a German family-owned company based in Weißenhorn (Bavaria) that has been developing and manufacturing filtration products for industrial solids and liquid filtration since 1995. The product range includes the in-house developed Cora® filter nonwovens in almost 60 nonwoven grades, pleated filter elements of the Cora®Pleat series, wound filter cartridges, filter bags, precoat nonwovens, filter cloths as well as bag and cartridge filter housings and high-flow filter systems. The nonwovens are converted on two in-house cutting machines in widths of 5 to 250 cm and wound onto cores of 70, 76 and 150 mm. Filtered media include coolants, emulsions, process and condensate water; fields of application include water treatment, seawater desalination, geothermal energy, electroplating baths and photo development. Housings are made of stainless steel 1.4301, 1.4404, 1.4571 and 1.4408 as well as PPGF and PVDF; bag filter housings are pressure vessels according to DGRL 2014/68/EU. Since 2025, the company with 25 employees has been part of the Swedish Amplex Group. All filters are produced at the Weißenhorn site (Made in Germany).
