A suction filter from WISY is absolutely essential for every rainwater installation. Increase the safety of every rainwater installation through preventing sediment and foreign matter from being suctioned out of the cistern.
Floating Suction Fine Filter: For drawing rainwater out of cisterns, ponds or wells. Prevents foreign matter larger than 0.3 mm. Fine filter housing with a spout that is easy on the hose, with or without a non-return valve. Standard type: spout 1”, 1 1?4”. No extra suction resistance is caused through the larger filter surface with this fine filter. This means the pump can develop its optimum effectiveness. The ball float allows the suction point to rise and fall with the water level and ensures that the water is taken where it is most clean: just below the water surface.
Floating Suction Coarse Filter: Stable type for drawing clean rainwater already filtered. Mesh size 1.2 mm. Coarse filter housing with a spout that is easy on the hose, with or without non-return valve. Standard types: spout 1”, 1 1?4”.
