Underground Integrated Quartz Sand Filter for Pool Water Filtration
High-purity quartz sand media ensures superior filtration down to 20 microns, removing fine debris for crystal-clear water. Durable corrosion-resistant fiberglass tank withstands high pressure and extreme weather conditions for long-term use. Fully automated backwash system with multi-port valve minimizes maintenance while optimizing water flow efficiency. Compact underground design saves space and integrates seamlessly with existing pool circulation systems. Ideal for commercial pools, water parks, and large residential pools requiring high-capacity filtration. Heavy-duty lateral assembly prevents sand leakage and ensures even distribution during filtration cycles. Energy-efficient operation reduces power consumption by 30% compared to traditional sand filters. Precision-engineered for heavy-duty continuous use with a flow rate of up to 50 m³/h.
