REPP Polypropylene Pre-filter

The combination of Cobetter REPP multi-layer membrane greatly improves the dirt-holding capacity and prevents the surface layer of the filter element from quickly clogging. The upstream pore size of the filter element is coarser and the downstream pore size is finer, which can intercept particles in a graded manner and greatly extend the service life. Suitable for filtering highly suspended particles, colloidal substances, and high-viscosity liquids. Distinctive features: high dirt holding capacity + ultra-high efficiency.
