Our revolutionary Maelstrom filters set a new standard in pre-tank rainwater filtering. Filtering multiple pipes at a single point, the Maelstrom’s unique U-shaped filter keeps leaves and debris down to 180 microns out of your rainwater tank. They also significantly increase your water catchment efficiency, even at high flow rates (96% at 10 litres per second in wet systems).
How it works:
Rainwater enters the Maelstrom through either of the horizontal-facing couplings.
The rainwater then enters the Primary Filter (J). The unique curved filter slows the velocity of the water by changing the direction of its flow.
Surrounding the Primary Filter is a Secondary Filter (C), comprising of a nylon mesh bag which filters fine particulates larger than 180 micron. This filter assembly is easily removable and will require periodic maintenance
The filtered rainwater then continues to move through the Maelstrom to the Filtered Water Outlet (F) and into the rainwater tank or pipe (if attached).

Features and Benefits:
A single point, tank-top filter with a ground breaking U-shaped design. The 180 micron filter screens particles 5 times smaller than is achieved with a standard tank screen.
Reduces the hassle of cleaning leaf and debris build-up through Self-flushing.
Blocks out light that supports algae growth.
Is a versatile product, able to be installed in a variety of pre-tank locations.
Reduces frequency and cost of tank cleaning by lowering common sediment build up through cleaner tank water.
Mounting plate fits 300mm, 400mm and 500mm tank openings, or can be used for mounting in-tank, on wall or in a pit.
