Raising the bar for rainwater filtering
The most advanced filter we’ve ever made, Maelstrom sets a new standard in pre-tank rainwater filtering.
International patent pending
Maelstrom’s ultra-fine 180 micron filter removes particles 5 times smaller than standard rain heads and tank screens.
Even at rapid flow rates of 36,000 litres (9,510gal) per hour, Maelstrom delivers up to 96% water catchment efficiency.
Efficiently filtering multiple lines at a single point is a simple way to keep tanks filled to the max.

A final 0.955mm (0.04") screen prevents
mosquitoes entering tanks to breed.
The filtered water is funnelled through
the base into the tank.
