About Cartridge Filters

WHAT IS A CARTRIDGE FILTER?

A cartridge filter is a modular filtration device used to remove contaminants from liquids or gases. It consists of a replaceable filter cartridge housed inside a filter housing. The media inside the cartridge traps solid particles while allowing clean fluid to pass through.

WORKING PRINCIPLE

1. Contaminated fluid enters the filter housing.
2. Fluid flows through the cartridge element (outside-to-inside or inside-to-outside).
3. Solids are captured on the cartridge surface or within its depth.
4. Filtered fluid exits, leaving particles trapped.
5. Cartridge is replaced or cleaned periodically.
