Mobile floor-cleaning machine includes polymer filter sheets with spacers guiding fluid flow to form filter cake which effectively cleans fluid flowing through

摘要

The filter unit includes filter sheets of polymer fabric or fleece. Each filter sheet is enclosed between two spacers. Passages at opposite edges of the assembly, provide for cleaning fluid inlet and dirty fluid outlet. Channels guide the fluid over the surface of the filter. The filter unit includes filter sheets of polymer fabric or fleece, 0.1-0.3 mm thick. At 2 mbar differential air pressure, air permeability of each sheet is 140-600 dm3/s. Each filter sheet is enclosed between two spacers. Passages at opposite edges of the assembly, provide for cleaning fluid inlet and dirty fluid outlet. Channels guide the fluid over the surface of the filter. As the fluid flows through, a filter cake layer forms. This effectively cleans fluid flowing through the filter.
