Filtre à sable bobiné (vanne latérale) 1400 mm
Taille: 1400 mm
Product Code: WS-1400
Category: Filtres à sable commerciaux
Filtre à sable commercial latéral bobiné, Ø1400 mm, pour piscines d'hôtels, de clubs et municipales. La cuve bobinée en fibre de verre est inoxydable et testée sous pression avant expédition ; la vanne multivoies latérale permet d'ouvrir le couvercle pour changer le média filtrant sans toucher à la tuyauterie. Média filtrant non inclus : le lit de support en gravier 1–2 mm et le sable siliceux 0,4–0,8 mm se commandent avec le filtre (quantités dans les caractéristiques). Le dimensionnement (débit de conception, vitesse de filtration et nombre de filtres) est confirmé par notre équipe d'ingénierie à partir du volume du bassin et du temps de recyclage.

Frequently asked questions
How do I size a commercial filter?
Public and hotel pools are filtered at a lower velocity than villa pools so the water stays clear under heavy bathing load. Each WS filter is rated at 30, 40 and 50 m³/h per m² of bed: at 30 m³/h/m² the WS-1200 passes 36 m³/h and the WS-2000 94 m³/h. Use the 30 m³/h/m² figure for public pools and split the duty across two or more filters in parallel so one can be backwashed while the pool stays in service.
What is the media charge?
The bed is at least 1 m deep: filtration sand 0.4–0.8 mm over a gravel support layer. The WS-1200 takes 1,600 kg of sand and 400 kg of gravel; the WS-2000 takes 4,400 kg of sand and 1,200 kg of gravel. The quick-closing manhole (300 × 400 mm on the WS-1200, 400 × 500 mm on the WS-2000) is sized for loading and changing the media without dismantling pipework.
What pressure and temperature are the vessels rated for?
Working pressure 2.5 bar, factory test pressure 4 bar, maximum water temperature 50 °C. Flanged connections run from 75–90 mm on the WS-1200 to 125–160 mm on the WS-2000, so the valve manifold and pipework should be sized to the same range.
Can Waterstar supply the valve manifold and media with the filter?
Yes — ask for the filter, its valve manifold, pressure gauges and the sand and gravel charge (25 kg bags) as one quotation so the plant room is commissioned from a single delivery. Send the pool volume, bathing load and plant-room drawing with the request and our engineers will size the set.
