FAQ — Self-Cleaning Filters & Strainers

A self cleaning strainer for cooling water is an automatic filter that removes suspended solids from cooling water systems, using self-cleaning mechanisms (like backwash or mechanical scraping) to keep water flowing uninterrupted.
These systems trap debris on a screen or mesh during filtration. When pressure builds up or at set intervals, the filter triggers a backwash or cleaning cycle — flushing out solids — while the rest of the system continues to run.
Yes — self cleaning filters are widely used in irrigation. They continuously filter water to remove sand, silt, and particulates, preventing pump clogging and ensuring reliable water supply for agriculture or landscape irrigation.
Yes — industrial self cleaning filters are designed for demanding applications including oil, process water, and chemical or petrochemical fluids. These filters maintain continuous flow while removing solids, protecting pumps, valves and downstream equipment.
