Kayser Filtertech

What Kayser Filtertech does

Kayser Filtertech Group is a privately held, family-owned industrial filtration systems manufacturer headquartered in Einbeck, Germany, with operating roots tracing to 1709. The company designs and produces custom filter bags, support cages, filter media (including proprietary ePTFE membranes branded KAY.TEX), and complementary elements for industrial air/gas and solid-liquid separation, with annual capacity of approximately 1.1 million filter bags and 250,000 support cages. Production is fully based in Europe across six facilities in Germany, France, the Czech Republic, and Italy, supported by wholly-owned subsidiaries and a network of more than 20 international sales partners covering Benelux, Austria, the Middle East, and North Africa.

The company's product architecture is organized around the KAY.CUBE platform, which bundles filter elements, cages, filter media, accessories, measurement and control systems, and field service into a single integrated offering with guaranteed 100% component compatibility. Differentiated product lines include KAY.KAT catalytic filter bags that combine NOx reduction with >99.99% particulate capture using TOP SOE technology, KAY.GREEN bags made from 100% recycled ocean plastic via a SEAQUAL INITIATIVE partnership, KAY.FOOD media compliant with EU and FDA food-contact regulations, and proprietary service offerings such as HEC in-situ cleaning and KAY.GLOW UV-based leak detection. ISO 9001 and ISO 14001 certifications have been continuously held since 1995.

Kayser generates revenue primarily through custom hardware sales of filter bags, cages, and filter media, supplemented by professional service revenue (KAY.SERVICE) covering installation, maintenance, cleaning, and laboratory analysis. The company sells to enterprise customers across eight verticals — biotech, chemicals and pharmaceuticals, energy, food and beverage, minerals and construction, waste treatment, wood and panel board, and metal/metallurgy — with a customer base of more than 1,500 globally. Pricing is quote-based on custom specifications rather than standardized list pricing, and go-to-market combines enterprise field sales from European offices, regional channel partners, annual customer seminars, and participation in industry events such as FILTECH.
