MaelstromĀ®
The MaelstromĀ® is a single-point pre-tank filter that removes particles down to 180 microns, five times finer than standard rain heads and tank screens. It mounts on the tank inlet, a wall, in a pit or in the tank, filtering multiple lines at one easy-to-maintain point.
Clean: Filter leaves and debris
Leaves, twigs and debris are the first things that clog and contaminate a rainwater system. Filtering them out early, before they reach your tank, protects your water quality and keeps everything downstream working as it should.
