Pullner high flow filter cartridge is mainly used for RO pre-filtration, seawater desalination, power plant condensate polishing, industrial water treatment, and other high-flow liquid filtration applications. It helps remove suspended particles and protect downstream RO membranes or equipment.

The standard diameter is 6 inches, around 152 mm. The large diameter design provides a bigger filtration area and allows higher flow rate compared with standard filter cartridges.

The flow direction is inside to outside. This structure helps intercept particles effectively and makes the cartridge suitable for high-flow water filtration systems.

It is a single open end design. Different end cap styles and sealing materials can be customized according to the housing and application requirements.

No. All connections are thermally welded without adhesives or binders, which helps ensure clean construction and stable filtration performance.
