The P-GFI sand filter system is designed for private use. The self-priming pump, including pre-filter, is supplied with water via rigid piping between the pump and the filter. In accordance with the NF P 90 316 standard, the P-GFI sand filter system is designed for a maximum operating pressure of 1.1 bar. The piping is connected via two 38 mm connections.

The water is fed through the filter system via a 6-way valve with 3 inlets and outlets. The filter base covers the entire filter surface, making installation easier (no individual attachment pieces) and the filter cover can be completely removed for easy access to the filter medium.

Fitted as standard with a black, UV-resistant ABS base. The filters are always supplied without filter medium and sand with a grain size of 0.6-1.25 mm is recommended.
