PP Sand Filter 2" FPT 3.75 bar Beige Type S790

Key Benefits

• Flow rate 22 m³/h and large diameter 790 mm – The S790 filter achieves a flow of 22 m³/h, which, with the filtration surface area resulting from the 790 mm diameter, effectively cleans water in pools up to 110 m³. This solution works well in both commercial facilities and large residential pools [poolsystem.pl](https://poolsystem.pl/pl/filtry-do-basenu/6459-filtr-piaskowy-do-basenu-75m3-750mm-z-zaworem-2-white-eagle-22-m3h-tebas.html).
• Durable polypropylene (PP) construction rated for 3.75 bar – The tank is made of high-quality polypropylene, resistant to corrosion, UV radiation, and aggressive pool chemicals. The maximum working pressure of 3.75 bar ensures safe operation even in demanding installations [bevo.com](https://www.bevo.com/pl-pl/norsup-filtr-piaskowy-pp-50-mm-1-1-2-gw-3-75bar-szary-typ-t450-7024559).
• Large filter media load – 250 kg of sand – The 250 kg media mass provides deep and thorough mechanical filtration. Quartz or glass media (AFM) traps dirt, sand, leaves, and other suspended particles, ensuring crystal-clear water. Sand replacement is recommended every 2–3 years, AFM media every 8–10 years [kambaseny.pl](https://kambaseny.pl/produkt/filtr-piaskowy-do-basenu-sr-750mm-z-zaworem-i-pompa-24m3-400v/).
• Universal 2" FPT connection and compatibility with 6-way valves – The filter features a 2" female threaded connection for easy installation into existing systems. The standard connection allows use with a 6-way valve (modes: filter, backwash, rinse, recirculate, drain, closed), providing full control over water treatment [robimybaseny.pl](https://robimybaseny.pl/produkt/filtr-do-basenu-hayward-nc780se2-22-m3-h-d780/).
• Saltwater resistance and wide operating temperature range – The polypropylene filter construction is fully resistant to saltwater, allowing use in pools with salt chlorine generators. Operating temperature range from 1°C to 43°C ensures performance in various climates [kambaseny.pl](https://kambaseny.pl/produkt/filtr-piaskowy-do-basenu-sr-750mm-z-zaworem-i-pompa-24m3-400v/).

Application and Performance

The PP sand filter S790 with a diameter of 790 mm and a flow rate of 22 m³/h is designed for pools up to 110 m³. It is suitable for commercial facilities (hotels, spas, water parks) as well as large residential and community pools. Thanks to the large filtration surface and 250 kg media load, it provides long cycles between backwashes, resulting in lower water and energy consumption.

The polypropylene (PP) construction ensures resistance to corrosion, UV radiation, and chemicals used for water disinfection. The filter can operate with fresh and saltwater, making it a versatile solution for various pool installations. The maximum working pressure of 3.75 bar ensures safe operation even in systems with high-performance pumps [bevo.com](https://www.bevo.com/pl-pl/norsup-filtr-piaskowy-pp-50-mm-1-1-2-gw-3-75bar-szary-typ-t450-7024559).

Model S790 is compatible with side-mounted 6-way valves (e.g., Praher or Peraqua), simplifying operation and maintenance. The valve allows smooth switching between filter, backwash, rinse, recirculate, and drain modes, giving the user full control over water treatment and quick response to changing conditions [poolsystem.pl](https://poolsystem.pl/pl/filtry-do-basenu/6459-filtr-piaskowy-do-basenu-75m3-750mm-z-zaworem-2-white-eagle-22-m3h-tebas.html).
