Sommer & Strassburger has developed a filter housing that uses an external pneumatic cylinder to clamp the inserts. This ensures reliable and even clamping independent of operating temperature. Moreover, the clamping force can be adjusted anytime from the outside.

Wetted stainless steel components are available in 1.4404 stainless steel in the standard version and in 1.4435 stainless steel on request. The material of the seals is EPDM with FDA certificate or, alternatively, USP-Class VI and BSE certificate. The specified operating pressure is -1 to +10 bar at a max. temperature of 140 °C. Surfaces can be manufactured to Ra ≤0.4 µm and electro polished. This new generation of module filter housing is available in four different lengths.
