Wisy Vortex filters offer the best in rainwater filtration and are widely used throughout the world. The unique construction and function of these filters provides several features not found in other types of filter.
By exploiting the natural ‘adhesive’ property of water (also known as the Coanda effect ) these special filters are able to have a vertical mesh surface. Because of this vertical construction, debris that gathers on the mesh surface is simply washed off and falls in to the waste outlet. Other rainwater filters have either flat or a slightly inclined surface, which is far more prone to blockage.
