What Is a Self Cleaning Filter

JX Filtration November 25, 2025 Self Cleaning Filter

A self-cleaning filter is an intelligent filtration device based on mesh interception. It uses an internal cleaning mechanism—such as suction nozzles, brushes, scrapers, or backwash jets—to automatically detect impurity buildup, clean the filter screen, and discharge contaminants.

It does not require manual removal or cleaning of the filter element, and it can perform self-cleaning without interrupting water or fluid supply. It is widely used for impurity filtration in water systems and industrial fluid systems. Its core function is to remove solid particles, suspended solids, and other contaminants from the medium to protect downstream equipment and ensure safe operation.

Core Advantages

With its core advantages of automation, continuous operation, low maintenance, and strong adaptability to harsh working conditions, the self-cleaning filter has become a key piece of equipment for water quality assurance in pumped-storage power stations.

Its applications cover the entire process—from water intake to unit operation and auxiliary systems. It not only protects expensive core equipment and extends maintenance intervals, but also improves operational reliability and power generation efficiency, reduces O&M costs, and fully meets the pumped-storage industry’s requirements for safety, efficiency, and flexibility.

It is an essential supporting device for the future intelligent and green upgrading of power stations.
