String-wound filter cartridges
Putsch® offers a very large selection of string-wound filter cartridges in many sizes, designs, materials and winding patterns.
These Putsch® filter cartridges are manufactured using a special process that creates a solid matrix structure with graduated permeability. The “grooved” structure increases the surface area of the filter cartridge, ensuring a higher dirt-holding capacity. Additionally, it prevents particle release as the differential pressure increases.
The entire production of phenolic resin-bonded acrylic fiber filter cartridges is carried out without the use of silicones.
The properties of the synthetic phenolic resin binder make it ideal for use in challenging conditions such as high temperatures, high fluid viscosities, and high differential pressures.
With over 150 years of experience, Putsch® is known for its expertise and excellent quality. Since we produce inhouse at our Hagen facility, we are highly flexible in the realm of customized products and delivery times.
Thanks to decades of experience, our company possesses extensive knowledge concerning special solutions and critical applications in the field of filtration technology.

Cartridge housings type “4” are robust stainless steel filter housings which are modular and accordingly versatile.
Cartridge housings type “6” have been used widely in all industries for over 40 years and are particularly popular due to their solid, robust quality.
Cartridge housings type “D” and “D-G” from Putsch® are manufactured individually to meet the requirements and special requests of customers.
Housings type “SM”, “SL” and “PN” are polypropylene cartridge housings for use as water filters, each with individual filter cartridges. Their low weight makes them ideal for mobile use.
Cartridge housings type “BB” are made of polypropylene filter housings designed for filter cartridges with a larger diameter which have particularly long service lives.
The customized cartridge housings type “D-PP” are made of polypropylene and are used wherever comparable metal housings are unsuitable, e.g. in an environment containing salt.
