The WISY Low Capacity Vortex Fine Filter is used in installations where multiple downspouts are connected to a single pipe into the vortex filter. A single unit can filter precipitation from a roof area up to 2,150 square feet for site irrigation, toilet and urinal flushing, janitorial use, laundries, fire protection, evaporative cooling tower make-up, process water, or other non-potable uses. The filter is typically installed in the underground piping system to direct debris to the stormwater system and divert up to 95% of clean rainwater to an underground storage tank. An above-grade application is also possible.
The WISY WFF 100 connects to a 4" pipe for above- or belowground storage. A 20-inch extension tube can be used to raise the inspection opening to ground level. The filter housing is made of polypropylene; filter insert is made of stainless steel. Filter mesh size is 0.28 mm (280 microns). Filter insert requires cleaning a few times a year and is dishwasher safe. Filter inlet can swivel for custom installation.
Parts included: filter housing, filter insert
Before entering the tank for storage, rainwater should be both filtered and aerated. Filtration removes large particulate matter, which frequently both carries and feeds bacteria. Removal of this particulate matter, along with oxygenation of the water, greatly reduces the amount of harmful bacteria in the tank. WISY pre-tank filters accomplish both of these tasks, protecting the water quality in the tank.
