filtre FRPThe FRP™ filters by Pentair have been designed to suit commercial swimming pools and other water applications. They are available in different sizes and configurations to fit all kind of needs.

 

Technical specifications:

 

  • Bobbin Wound polyester filters, 1m. Filtration bed with arm collectors.

 

  • Filament winding technology (With this technology it is possible to produce tanks of high elasticity and high pressure resistance). As a result of the combination of different processes (lamination, glue and filament winding) and materials (fibreglass and resins) the tank has a flexible body that achieves the best resistance against high pressure with less wall thickness.

 

  • Possibility of production of large size filters.

 

  • The filters are not painted. Instead of this the fibreglass filaments are impregnated with paint during the process of filament winding. This method and the use of a furnace that speeds up the process of desiccation of the filter avoid the sweat effect on the tank surface when the filters are on place.

 

  • Chemical resistance of the filter tank achieved by the chemical resistance of the polyester itself. (Low emission polyester resins with anti-rust properties).

 

  • Witness pressure gauge installed in the tank (integrated to the filter).

 

  • Water drain and Sand outlet.

  • Ringbolts are installed in filters from Ø1800mm.

 

  • All filters are tested 1,5 times its working pressure.

 

  • DIN inlet and outlet connections with PVC flanges.

 

  • Arm collectors (most economical, of easy service and maintenance). The laterals have a slot of 0,4mm.

 

  • Nozzleplate available upon request.

 

  • Available in 2.5 and 4 bars – filtration speed 30-40 m³/h/m².

 

  • Manhole on top with special closure and air relief valve in the lid.
