Commercial Sand Filter — Side Mount
Size: 1400 mm
Available options
- Size: 1200 mm, 1400 mm, 1600 mm, 1800 mm, 2000 mm
Product Code: WS-1400
Category: Commercial Sand Filters
Made in five sizes: Ø1200, 1400, 1600, 1800 and 2000 mm. Filament-wound side-mount commercial sand filter, Ø1400 mm, for hotel, club and municipal pools. The fibreglass-wound tank is corrosion-free and pressure-tested before dispatch; the side-mounted multiport valve lets the lid be opened for media changes without disturbing the pipework. Media is not included: order the 1–2 mm gravel support bed and 0.4–0.8 mm silica sand with the filter (quantities in the specifications). Sizing (design flow, filtration velocity and number of filters) is confirmed by our engineering team from the pool volume and turnover time.

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 filters are supplied empty — the media is ordered with the filter. The charge is filtration sand 0.4–0.8 mm over a 1–2 mm gravel support layer: the WS-1200 takes 1,375 kg of sand (55 bags of 25 kg) and 300 kg of gravel (12 bags); the WS-2000 takes 3,800 kg of sand (152 bags) and 1,050 kg of gravel (42 bags). 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.
