The WISY 4-STEP Rainwater Harvesting System ensures that your rainwater will not only become clean but also stay so during the storage period. By relying on an almost vertical filter mesh, the WISY filter is self-cleaning and automatically removes dirt and debris, resulting in a minimal system maintenance.
The WISY 4-step rainwater harvesting system ensures that your rainwater is clean enough to store.
Note: All three videos show the operation when water enters the filter simultaneously from different angles. This example displays a WFF150 Vortex Fine Filter.
When water falls through a vertical tube, it tends to cling to the inner surface of the tube. This behavior is caused by adhesion forces which can be exploited to alter the direction of water flow. Solids do not behave in this way, they just fall straight down. Furthermore, they are captured by the fine stainless-steel mesh of the filter. Only clean water can pass into the storage tank or back to the production process.
The cross-sectional area of the connected tubing does not change at any point inside the filter housing so that larger debris particles can pass straight through. Even a tennis ball washed off the roof cannot block the rainwater pipe.
Leaves and particles cannot clog the filter
