Industrial Textile Filters and Technical Textiles from the Manufacturer
WINKLER makes textile filters for industrial solid liquid filtration. Filter bags, filter cloths for chamber filter presses, anode and cathode bags, nonwoven filter roll media and centrifuge liners are cut, sewn and assembled in our own production in Werther, Germany. We are a manufacturer of filter media rather than a reseller, which is why a standard size from stock and a part made to your drawing come off the same machines and past the same people.

Industrial filtration products by product group
Nine product groups, sorted by the job they do rather than by industry. If you know which part you want to replace, this is the short route. If you do not, the route through the application is usually shorter. Most of what you see here is liquid filtration: the filter medium separates solids from a liquid, and the housing, press or centrifuge around it stays yours. A few groups, such as pond and well protection, are also bought outside industry.
Sludge Dewatering & Paint Sludge
Dewatering bags from 0.125 to 1.25 m³ for sludge, confirmed drilling applications and paint sludge.

We are a filter bag manufacturer, not a trading company. As an industrial filter supplier with its own sewing room we make standard sizes and special versions on the same machines, in the same hall in Werther. For the common jobs there are graded standard sizes on the shelf. For everything else we build to measure, to a drawing, or to a sample you send in.
Buyers often search for filter media manufacturers and filter media suppliers as if the two were the same thing. They are not. A supplier ships you the roll; a manufacturer turns it into the part your plant actually takes. We do both, in the same building, which is also why we are listed among filter cloth manufacturers and liquid filter bag manufacturers rather than in only one of the two.
What actually fits is decided by the medium, the type of solid, the installation dimensions and the question of how the filter gets changed. A bag that separates well but cannot be lifted out cleanly helps nobody. That is why we check whether a standard size covers the case before we quote a special size. That step is where most industrial filter solutions are won or lost, and it costs one email.

Find the right product
You know which product group fits but are unsure about size, material or grade? A short form is usually enough, and often the chat is quicker still.
Start product adviceDevelop a custom filter solution
For new processes, changed service life, prototypes or series projects the product question is not the right one. Then we need a drawing or a sample, plus medium, temperature, chemistry, load and quantity, and often a look at the plant itself.

Sewing room and filter assembly
Filter bags, filter cloths and technical textile components are made here to released dimensions and released materials. Nothing in this range is bought in and relabelled.
Technical textile laser cutting
Two eurolaser L-1200 conveyor systems cut textile roll material up to 1,800 mm wide from a DXF file, a drawing or an approved sample. From a single sample part to series, in your material or in ours.

A new geometry, an unusual medium, a process with no catalogue part: we work out the version with you and build it in Werther.

WINKLER develops and manufactures textile filter solutions for solid liquid filtration, for industry, municipalities, trade and private use. Because assembly, prototyping and cutting all sit in our own building, the standard product and the special build come out of the same workshop and are checked by the same people. That is the practical difference between an industrial filtration company that manufactures and a catalogue supplier that ships. Industrial filtration companies usually sit on one side of that line, either producing media or assembling parts; here both sit in the same hall.
Among technical textile companies and technical fabric manufacturers our range is unusually narrow and unusually deep: we do not print, we do not embroider, and we do not do decorative work. We cut, sew and assemble technical fabrics, and most of what we make ends up separating something from a liquid.
