MF Series Modular Self-cleaning Filter


MF Series Modular Self-cleaning Filter , designed on the base of modular concept, MF filter consists of several standard filter units and has high safety redundancy. And the operator can flexibly add online filter units to the exsiting system for higher flowrate or dirty load capacity. MF filter works automatically and is easy for capacity expansion. It can works in low pressure condition by flushing with external high-pressure back-flushing fluid. It adopts the unique V-SLOT filter element, which can be back-flushed clean thoroughly and costs less of back-flushing liquid. When filtering some viscous impurities or fibers, it is easy to open for periodic manual cleaning. MF filter not only can purify fluid, protect key equipment, but also can reclaim expensive solid particles from the back-flushed liquid. MF filter adapts to low viscosity liquids, such as raw water, sewage, gasoline, heavy gasoline, diesel oil, residual oil.
