The 3P Sinus Filter is recommended for retro-fit applications where no height difference can be achieved between the rainwater inlet pipe and the outgoing waste water pipe. Filtered water is deposited downwards, making the Sinus filter best suited for installation within the rainwater storage tank. The filter efficiency is enhanced by the staggered inlet and outlet, forcing the water to change direction twice,  therefore increasing contact area with the filter surface.

All inlets and outlets fit standard 110 mm drainage pipe.

The 3P Sinus Filter is available with a backwashing device (self cleaning jet).
