WISY 4-STEP SYSTEM

1. PRE-FILTRATION // 2. SMOOTHING INLET 
3. FLOATING INTAKE // 4. OVERFLOW


A rainwater system designed with WISY products requires minimal maintenance and never needs replacing.
With a WISY filter, you'll never clean your tank again.

WISY Advantage

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. WISY Filters are also self-cleaning and require minimal annual maintenance.

HORIZONTAL RAINWATER FILTERS

 
WISY LineAr100 Filter Stainless Steel
560.00

Filters up to 2,100 sq. ft.

Whether for new construction or retrofits: The space-saving LineAr 100 rainwater filter is easy to accommodate and can be installed without any extra excavation work. There are just 2" of height difference between the rainwater inlet and the dirty water outlet. Thanks to this minimal height difference, the LineAr 100 rainwater filter is very easy to integrate into existing pipework. It can even be placed directly inside a rainwater storage tank without changing the gradient of existing piping.

The WISY LineAr 100 differs from the WISY Vortex Filters in that the difference between inlet and overflow inverts is minimal, the LineAr still maintains a vertical filtration method. Leaves, moss and other suspended particles are simply flushed past the filter into the drain outlet. This is the crucial advantage of this design over filter surfaces that are almost horizontal and become clogged with dirt very quickly. The pipe diameter is uniform throughout the LineAr 100 Rainwater Filter. 

The harvested rainwater is not only clean, but naturally soft as well. It has ideal quality for flushing toilets, washing, or irrigation.

The WISY LineAr 100 connects to 4" piping for all three connections. The stainless steel filter removes particles larger than 440 microns (0.017") from the water that enters into the tank. Maintenance is minimal, and is usually only done 2-3 times per year.
