Pool pre-filter insert — precision conical design that protects your main filter and reduces maintenance Why you need it Prevents large debris from reaching the main filter, reducing clogging and extending cartridge life. Cuts maintenance time and effort with easy-to-clean design. Improves overall pool circulation and pump performance by keeping coarse particles out of the primary filtration system. Key benefits and how it solves problems Effective debris barrier: Precision-made conical shape seats exactly in the inlet to block coarse particles up to 5 mm, keeping leaves, twigs and grit out of the main filter. Longer-lasting main filters: Acts as a pre-filter to relieve mechanical stress on primary cartridges, lowering replacement frequency and maintenance cost. Reliable stability: Honeycomb internal structure with double-reinforced side walls resists deformation under flow and pressure, preserving shape and function over time. Faster cleaning and better flow: Wide opening and smooth interior surfaces allow quick, thorough cleaning and easier debris removal, which helps maintain pump efficiency. Standout features Precision-formed honeycomb structure for high stiffness and balanced load distribution Double-reinforced side walls to prevent warping and maintain a consistent seal Conical geometry engineered for an exact seat and minimal bypass Captures particles up to 5 mm to protect the downstream filter cartridges Smooth internal finish and large access area for simple maintenance Function, compatibility and performance Function: Acts as a pre-filter/dirt barrier upstream of the main pool filtration system Compatibility: Designed for use with pool filtration systems that accept a conical pre-filter insert; the precision conical seat minimizes bypass and maximizes protection Performance: Effectively removes coarse debris, reduces mechanical wear on main filters, and supports stable pump operation by maintaining more consistent flow Practical use scenarios After storms or heavy winds: traps leaves, twigs and larger organic debris before they reach the main cartridges, preventing rapid clogging. High-traffic or seasonal pools: reduces load on primary filters during peak use periods, extending service intervals and lowering maintenance effort. Routine maintenance intervals: simplifies cleaning tasks—remove the pre-filter, rinse or wipe smooth surfaces, and reinstall to restore full protection quickly. Technical highlights (quick reference) Particle capture: up to 5 mm Structure: precision-formed honeycomb with double-reinforced side walls Shape: precision conical seat for exact fit Maintenance: wide opening and smooth interior for easy cleaning Reliable, practical protection for your pool’s filtration system — reduces filter wear, shortens cleaning time, and maintains better pump performance.
