General
Technomax SCSF Series are automatic filters, with an electric self-cleaning mechanism. The “SCSF” filters range in flow-rates of up to 1800 m³/h (8000 US gpm), with screens designed ranging from 800-10 micron filtration degree. Inlet/Outlet ranges are available from 8”- 20” diameter.
Raw water enters from the filter inlet
- and passes through the screen
- Clean water flows through the filter outlet
- The gradual dirt buildup on the inner screen surface causes a filter cake to develop, with a corresponding increase in the pressure differential across the screen. A pressure differential switch
- senses the pressure differential and when it reaches a pre-set value, the cleaning process begins.
The Cleaning of the filter is carried out by the suction scanner
(5) which spirals across the screen, the open exhaust valves creates a high velocity suction stream at the nozzle tip which “vacuums” the filter cake from the screen. During the self-cleaning process, which takes approximately 30 seconds, filtered water continues to flow downstream.
