Oslo Filament-Wound Sand Filter – Public Pools

Oslo filament-wound filters are made of isophthalic polyester and fibreglass and have a 1.2 m filter bed. They come with a pressure gauge, air purge and water drain valve; a Ø 400 mm lid and 2½" sand drain plug are standard.

The filters suit filtration rates of 20, 30, 40 and 50 m³/h/m²; the catalog selection is given for 30 and 40 m³/h/m² (for example Ø 1600 mm: 2.01 m² × 30 ≈ 60 m³/h). Each diameter and rate has separate order codes for 2.5, 4 and 6 bar maximum working pressure.

The standard distribution is a collector-arm system, with a nozzle plate system as an option; a side manhole is recommended for nozzle plate filters. The filter can be filled with single-layer, multilayer (anthracite + sand + gravel) or glass media. The valve collector is sold separately; the filter code excludes media and the valve collector.
