The WISY VORTEX filter is unique with its patented design that uses the principle of adhesion, where water ‘sticks’ to a smooth surface, in this case the outer layer of a vertical cylinder. This process causes the water to ‘pull’ through the fine mesh inner layer, leaving behind any leaves, insects and any other particles greater than 0.28mm. The filtered debris then either falls straight through centre of the filter, or is washed off by the action of the flowing water. This unique design means that the debris is simply washed away to the storm drain and out of harms way.
