As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we are proud to present our 304 Stainless Steel Swimming Pool Sand Filter with integrated 1.5HP pump and 2500GPH flow rate. This system is engineered for durability and efficiency, combining a robust 304 stainless steel tank with a high-performance top-mount multiport valve.

Why Choose Our Sand Filter?
Our factory has been a trusted name in the industry since 1998, exporting to dozens of countries worldwide. We use precision welding and quality control to ensure every tank meets strict standards. The 304 stainless steel construction not only provides superior strength but also simplifies maintenance—no painting or coating needed. The 1.5HP pump is designed for quiet operation, and the top-mount valve eliminates the need for complex plumbing.
Compared to traditional cartridge or DE filters, our sand filter requires less frequent cleaning and replacement. A simple backwash every few weeks restores performance, and the sand lasts 5-7 years before replacement. This translates to lower operating costs and fewer headaches for pool owners.

Frequently Asked Questions

Q: Can this filter be used with saltwater pools?
A: Yes, the 304 stainless steel tank is resistant to saltwater corrosion. However, we recommend rinsing the exterior after prolonged exposure to salt spray. -
Q: How often should I backwash the filter?
A: Backwash when the pressure gauge reads 8-10 PSI above the starting pressure, typically every 1-2 weeks depending on usage. Always follow the manufacturer's guidelines. -
Q: Does the pump come with a cord and plug?
A: The pump is pre-wired with a cord; a plug may be included depending on the destination. For North America, a standard 110V plug is provided. For other regions, we can customize the plug type upon request. -
