Strainers stop particles

To achieve this effectively and precisely, Berger Tools now has new strainer-based pressure compensation components under the standard code GN7403. 

The key feature is a stainless steel strainer embedded in polyamide with a precisely defined mesh size of 100 µm or 500 µm. Berger Tools strainers therefore provide an effective bidirectional barrier to stop dust, dirt particles or pollutants dispersed in the gas phase. Particles with diameters greater than the mesh size therefore can neither exit nor penetrate the device during pressure equalization.

The outside diameter of strainer components with recessed hexagon matches the bolt mounting holes for DIN 3852, and their thread length allows for different wall thicknesses.

Made from aluminum or stainless steel, each component has a sealing ring embedded in a radial and plane-sided recess which makes the seal captive, preventing it from being squeezed out during tightening. And for finished look, Berger Tools offers the additional solution of a mounting nut GN543.1
