It is an automatic washing system that enables the electrostatic or other washable filters to be cleaned inside its own cabinet without removing outside. It consists of water inlet selenoid valve (1), closed pressure tank (2), exit selenoid valve (3), spraying pipe punched along (4), pressure sensor (5), dosage pump (6) and pressurization pump (7).
Water comes from city water network is (stored and pressurized) accumulated in closed pressure tank (2) its pressure increases by its own city water network pressure, high pressure water accumulated in closed pressure tank (2) is released to spraying pipe punched along (4) through selenoid valves (1) (3) in some periods as pressure reaches to some certain values. Spraying pipe punched along (4) has holes and slots opened on it instead of nozzles. If city water network pressure is not enough a small pressurization pump (7) is added to increase accumulated water pressure.
