Automatic Back Wash Filters

Filter Sep Technologies offers Automatic Back Wash Filters. The automatic filters are in shape of simplex basket filters having off-set or in-line end connections. The combination of solid & hollow back wash arm is coupled to geared motor at one end and to back wash drain nozzle at the other end.

Timer based automation logic is also additionally incorporated in electrical control panel which operates in case of d.p. switch failure. Degree of filtration offered is down upto 100 micron.
