Sieve basket filters

Sieve basket filters (S11 and S21)

Standard and inline

Sieve basket filters are employed for coarse or pre-filtration of liquid, viscous and gaseous media. With our series, you will find sieve basket filters for almost all fluids and flow rates. Our sieve basket filters in a welded design are available as single or double filters with fittings, instrumentation and interconnecting pipes.
We are able to complement our standard sizes as needed with specially made products tailored to your use case, for example, with custom shapes and dimensions, other levels of filtration fineness and other materials.

Application areas
