Vesubio (Volcano) Sand Filter – Public Pools

The AstralPool Vesubio (Volcano) public pool series is a laminated sand filter made of isophthalic polyester and fibreglass, with a collector-arm distribution system and a 1 m filter bed. The filters come with a pressure gauge, air purge and water drain valve; a Ø 400 mm lid, 0.3 mm diffuser distribution and a 2½" sand drain plug are standard.

Each diameter is selected for a filtration rate of 20, 30, 40 or 50 m³/h/m²; the flow rate equals the filtration surface area multiplied by the chosen rate (for example Ø 1600 mm: 2.01 m² × 30 m³/h/m² ≈ 60 m³/h). The connection size (63–160 mm) and order code change with the selected rate. Maximum working pressure is 2.5 bar.

A side manhole (Ø 225 mm), sight glass (Ø 75 mm), vinylester lining for ozonated water (max. 0.5 ppm ozone, 40 °C), seawater use (max. 45 g/l salt) and drinking water use are available as options. The valve collector system is sold separately; the filter code excludes filter media and the valve collector.
