Filter bags

Woven and nonwoven filter bags serve primarily as a replaceable filtration element for capturing solid particles from liquids. Sewn-in rings or welded-on plastic flanges hold them in the filter housing. We also make bags with a drawstring or with no ring at all.

Reliable liquid filtration calls for precision in every detail. We manufacture industrial filter bags that protect your equipment and keep your processes clean. Careful material selection and honest workmanship keep efficiency high throughout the bag's service life. Whether you need a standard design for a common filter housing, a fully welded bag for critical applications, or a specific custom size, our family workshop adapts to your requirements.

Filtration range from 1 micron

We cover everything from coarse surface filtration with mesh fabrics to fine depth filtration with microfibres. We reliably capture solid particles, gels and deformable contaminants across a wide range from 1 to 1,500 microns.

Seamless welded joints

For the most demanding applications we make fully welded bags. With no holes from sewing needles and solid sealing collars, we minimise the risk of liquid bypass and keep the filtrate clean even under pressure surges.

Materials for every operation

We process polypropylene, polyester, nylon, viscose and heat-resistant Nomex. Our filter media stand out for their chemical resistance, and we can also meet strict food and pharmaceutical standards (without the use of silicones).

Extended service life and absorption

We also offer advanced solutions. The asymmetric structure of our extended-life media reduces maintenance costs, while special microfibres deliver highly efficient absorption of oils and hydrocarbon substances.

Fixing and made-to-measure sizes

As standard we fit bags with steel or stainless-steel rings or plastic flanges. We make common catalogue sizes too, but as a direct manufacturer we can quickly sew any custom size to fit your filter housing exactly.

Steel ring, or plastic flange?

It depends on your filter housing and your cleanliness requirements. We will advise whether a classic sewn-in metal ring is enough, or whether a fully welded plastic flange with a perfect seal is the better choice. Standard diameters at the ring/flange:
100 and 180 mm

Which bag material should you choose?

Lost in terms like polypropylene, polyester or nylon? We take into account the type of your liquid, the operating temperature and the chemical composition, and recommend a filter medium that lasts the longest.

Do you also make custom bag sizes?

Yes, that is a major advantage of ours. As a direct manufacturer we are not tied to standard tables. If your equipment needs a specific length, diameter or shape, we will sew bags exactly to measure for you.
