What are the cleaning mechanisms of self-cleaning filters?

Types of Cleaning Mechanisms for Self-Cleaning Filters

Brush Type

Equipped with rotating stainless steel or nylon brushes to mechanically remove impurities. Simple structure, suitable for granular and sediment contaminants.

Suction Type

Adopts rotating suction nozzles to remove impurities via negative pressure. High cleaning efficiency, ideal for fine suspended solids.

Scraper Type

Uses elastic scrapers to scrape viscous and sticky contaminants. Suitable for high-viscosity and oily water conditions.

Backwash Type

Cleans the filter screen by reverse water pressure. Low cost, widely used for small-scale and low-pressure systems.
