Super clean oxygenated water is only achieved with the WISY VORTEX filter.

WISY are renowned for their ingenuity and engineering excellence. 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 avoids the possibility of leaves etc. breaking down on the filter surface or within the tank. This also means that the debris is simply washed away to the storm drain and out of harms way.

The VORTEX filter also oxygenates the water to keep quality at its peak and inhibit the growth of anaerobic bacteria, which can cause the water to develop bad odours.

It’s no wonder the VORTEX filter is the chosen filter for thousands of projects across Europe, ranging from small domestic systems right up to huge commercial jobs like the Maracana Sports Stadium.

Used across the globe for:
  • Domestic Rainwater harvesting systems
  • Commercial Rainwater Harvesting systems
  • Storm water drainage filtration
  • SUDS filtration
  • Liquid extraction in manufacturing
What makes the WISY VORTEX filters unique?
  • They add oxygen to the water.
  • They remove leaves and debris straight away, rather than leaving them to degrade in the water.
  • They require no tank entry to clean
  • Finest filtration – mesh size of 280 microns.
  • They use patented technology to extract the cleanest water.
The positive affects of oxygen within water

The most important function of any rainwater filter is the removal of as much debris as possible from the flow of water.  If organic matter is allowed to accumulate on the filter screen, or worse still in the bottom of a sump, this will be detrimental to the quality of the water. Decaying organic matter strips oxygen from the water, leaving it stale and with bad odour. The Wisy vortex filter has a vertical filter mesh, ensuring that leaves and debris cannot adhere. Its unique design ensures that additional oxygen is incorporated during filtration, resulting in clean, clear, odourless water.

Easy cleaning in 3 simple steps

Cleaning of the WISY vortex filter is simple and safe. Just use the supplied handle to remove the mesh cartridge, clean it with a brush under warm water and replace it periodically to continue to get the positive benefits of the filter.
