Vesubio (Volcano) Sand Filter

AstralPool Vesubio (Volcano) is a side-mount sand filter whose laminated body is produced by simultaneous projection of isophthalic resin and fibreglass. Its Ø 210 mm threaded lid with high-resistance screws makes servicing and media changes easy; the Ø 1050 and Ø 1200 mm models are also available with a Ø 400 mm top lid.

The filters are sized for a filtration rate of 50 m³/h/m²; the flow rate equals the filtration surface area multiplied by this rate (for example Ø 750 mm: 0.44 m² × 50 m³/h/m² ≈ 22 m³/h). Maximum working pressure is 2.5 bar; the filter accepts sand or glass media and meets the filtration requirements of EN 16713-1.

Model selection is based on pool volume and turnover time: with an 8-hour turnover, the Ø 450 mm model serves about 64 m³, the Ø 900 mm model 256 m³ and the Ø 1200 mm model 448 m³ of pool water. Ø 450–900 mm models are supplied with a side-mount multiport valve, while the Ø 1050 and Ø 1200 mm models are supplied without a valve (bare).
