Explosion pressure relief at explosion pressure shock resistant Herding filter unit Explosion suppression at explosion pressure shock resistant Herding filter unit Herding PHARMEX

Explosion protection


Fine dusts consisting of organic and metallic components are liable to oxidation - dust clouds can explode!

If ignition sources exist in spite of preventive measures, the Herding® filter unit must be equipped with explosion protection devices.


The Herding® filter units for higher resistance to explosion can be designed with measures for pressure relief or suppression.

Alternatively, an upgraded Herding filter unit with volume limitation as higher-resistance-to-explosion version is available.

Measures for blocking off explosions in the pipe line and during discharge to upstream and downstream units are introduced in addition.


The filter unit's higher resistance to explosion is calculated, optimized with water pressure testings and verified in an explosion test.
