How Water Screen Filters Work

Water passes through a screen that retains particles larger than its effective openings. The housing directs flow through the screen while seals prevent an unintended bypass path.

How it applies to the water system

As retained material accumulates, the pressure loss increases and cleaning becomes necessary. Manual, semi-automatic and automatic cleaning arrangements require different operator involvement.

Selection and operating considerations

Screen grade, active area and rated flow must suit the application. Check the manufacturer data rather than treating every filter with the same connection size as equivalent.

Planning the requirement in Sabah

A workshop, commercial building or irrigation site in Sabah may need particle protection at different points in the water line. Identify the component being protected and its filtration requirement, then review the space and cleaning access available around the proposed filter.

Information to prepare

What should I send SWFI for this requirement in Sabah?

Send the site location, source-water information, operating flow and pressure, and the equipment model or photographs where available. SWFI is based in Kota Kinabalu and can review the requested supply or service scope against the site duty.

Discuss your water-system requirement with SWFI
