Designed and produced in Hagen Germany by a team with decades of experience in filtration and manufacturing. We've been fortunate to serve customers across many industries and faced almost all conceivable filtration challenges. This experience has allowed us to research, develop, and optimize a range of quality filters that are designed to provide a high return on investment. We even trace filter components all the way back to their raw material supplier, to ensure the consistency, quality, and reliability we're known for.
String-wound filter cartridges
For decades, Putsch® has manufactured a large selection of string-wound cartridges in many dimensions, designs, materials and winding patterns.
"HP" type depth filters
High performance depth filters made from polypropylene; known for their longer service life.
"CX" type depth filters
This is the premium product of the melt blown filter cartridges. Made from precisely defined microfibers and designed for customers who require very high purity.
"K11" type pleated depth filters
The uniform thermally bonded matrix of the "K11" creates a homogeneous filtration layer that is optimal for ultrafine particles.
"K01" type membrane filters
A polyethersulfone membrane allows this cartridge to filter particles and bacteria down to approximately 50 µm.
"PGP" type mesh filters
Versatile and reusable filter cartridge made from polypropylene mesh. It's easy to clean and can quickly be converted to other lengths and/or grades.
"MGG" + "MGP" type metal mesh filters
Stainless steel mesh filter cartridges are specially made for operation at high temperatures or with specific chemicals.
"PA-G" type activated carbon filters
Specially designed with steam-activated coal pellets for strongly contaminated liquids. The bulk form prevents the activated carbon surface from being blocked by coarse sediments, making the useful life extremely long.
"GAC" type activated carbon filters
Activated coconut coal granulate is used in this cartridge for low dynamic pressure and a longer life. The design allows liquid to pass through the entire filling increasing contact times and thus adsorption.
"EPS" type activated carbon filters
Made from a solid homogeneous charcoal block, the "EPS" provides constant adsorption across the entire cartridge. In addition to applications in liquids, these filter cartridges are also suitable for air and gas purification.
"PRO" type filters
Phenolic resin-bound acrylic fibers address the special requirements of paint and varnish filtration.
