Waterco MultiCyclone Centrifugal Pool Pre-Filter

At a Glance

The Waterco MultiCyclone is a centrifugal pre-filter for swimming pools. It sits between the pump and the sand or cartridge filter and spins most of the dirt out of the water before it ever reaches the filter, so you backwash less, clean cartridges less and waste less water.

Ideal for

• Sand filter pools that backwash too often
• Cartridge filter pools that need the element cleaned every few weeks
• Pools with an automatic cleaner or in floor cleaning, where the filter takes a hammering
• New pool packages and upgrades to an existing pool, it suits both

Key Specs

• MultiCyclone 12 (200371): 40mm / 1 1/2" quick fit unions, 12 hydrocyclones, flow range 40 to 300 litres a minute (2.4 to 18 m3/hr)
• MultiCyclone 16 GEN2 (200502): 50mm / 2" quick fit unions, 16 hydrocyclones, flow range 50 to 500 litres a minute (3 to 30 m3/hr)
• MultiCyclone PRO (200385): 50mm, the higher pressure commercial version of the 16, for plumbing that runs above the domestic 350 kPa limit
• MultiCyclone PRO 7 Bar (2003850): 50mm, rated to 7 bar (700 kPa)
• Max pressure (12 and 16): 350 kPa (50 psi), fit a pressure regulating valve upstream if your pump or supply can go higher
• How much dirt it takes: up to 80% of the dirt load, with no drop in flow as the dirt builds up
• Cleaning: open the 25mm purge valve and about 15 litres goes to waste. No filter media to clean or replace
• Build: glass filled thermoplastic, UV and corrosion proof, with a clear sediment chamber so you can see when it is full
• Water temperature: above 0C and below 45C
• Catches: sediment heavier than water. Floating debris is not caught, so keep the skimmer basket in place

Why We Like It

It has no moving parts and nothing to replace, which is rare in pool gear. Waterco says it can cut a sand filter to one backwash a year, saving up to 7,000 litres of water a year on an average home pool. Pick the size by your pump's flow, not your pool's volume: the 12 for pumps up to 300 litres a minute, the 16 for bigger pumps. If you are not sure, tell us your pump model and we will tell you which one. One catch: do not add granular pool chemicals through the skimmer with this fitted, unless you can bypass it.

Installation

It is plumbed in after the pump and before the filter, with the purge valve piped to a waste line. Fit it yourself, or use a pool installer or plumber. Mount it level on firm ground or on the optional Waterco MultiCyclone stand.
