Large flow automatic self-cleaning filter

Product description

Large flow automatic self-cleaning filter is composed of stainless steel filter element in a tank body, and its main components are composed of filter element and sewage suction device. During filtration, sewage enters from the lower part of the filter and distributes to each filter element. The sewage is filtered from the inside to the outside of the filter element. Solids in sewage are trapped by the filter screen; An electric motor drives the cleaning mechanism to rotate and move up and down the sucking scanner. 

The sucking scanner is connected with a blowdown valve. When the blowdown valve is opened, the pressure difference between the internal water pressure of the filter and the external atmosphere makes each suction nozzle produce strong suction. The cleaning process takes about 35-60 seconds. The screen of the filter is cleaned in turn. In the whole reverse cleaning process, the system does not break the flow.
