JX Filtration October 29, 2025 Self Cleaning Filter

A self-cleaning filter is a fully automatic filtration device with a filtration accuracy range from 20 μm to 5000 μm, capable of meeting a wide variety of filtration requirements.

It mainly consists of a housing, filter element, cleaning brush, drain valve, controller, and sealing rings, and is designed to purify liquids and protect downstream equipment by ensuring stable system operation.

The self-cleaning filter operates automatically using the pressure of the liquid, allowing for continuous online filtration and automatic self-cleaning without the need for manual replacement or cleaning of filter elements. It produces no disposable filter materials, effectively overcoming the inconvenience of frequent manual cleaning and replacement required by traditional filters.

This type of filter is widely used in applications such as water treatment, oils, acid and alkali solutions, polymers, paints, and other viscous materials. It is highly efficient, performs reliably, and offers excellent cost-effectiveness—making it a popular choice in the market.
