Benefits

Get cleaner water in your tank

The Maelstrom®’s ultra-fine secondary filter removes particles down to 180 microns – 5 times finer than standard rain heads and pre-tank filters. This gives you cleaner, better quality water and lowers the volume of sediment putting pressure on your tank pumps and post-tank filters.

Get more water, faster

The Maelstrom® eliminates the problem of water splashing off your tank inlet screen, especially at high flow rates. Its phenomenal water catchment efficiency (96% at 3,600 litres/hour in wet systems) gives you more water, faster, so you can take full advantage of every raindrop.
 
Get water effortlessly
 
The Maelstrom®'s initial 2mm filter diverts leaves and debris which are then flushed out during rainfall events. Because the revolutionary design is low-maintenance with no mechanical parts, it does this with minimal effort from you.
