Surface filtration

Dust particles are retained on the surface of the filter medium for surface filtration. Dust particles form a filter cake, which takes over the actual filtration. Dust separation increases as the thickness of the filter cake layer increases. Differential pressure rises and volume flow decreases. Cleaning the filter elements counteracts the rising pressure and thus the reduction of the volume flow. Consistent suction conditions result during continuous cleaning for classic surface filtration at the bissinger filter.
