Filtering up to 2100 square feet of roof surface, Wisy's all new Linear100 pre-tank filter ranks the highest in our field tests for quality, affordability, and function. With just 2 inches of height difference between the rainwater inlet and the dirty water outlet, the Linear 100 rainwater filter is very easy to integrate into existing pipework, and can even be placed directly inside a rainwater storage tank without much adjustment to the pipe elevations. See our example of a cistern component layout for tips on how/where to install the Linear filter.
The WISY Linear100 differs from the WISY Vortex Filters in that the difference between inlet and overflow inverts is minimal, yet 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 WISY Linear 100 connects to 4" piping for all three connections, with the gasketed inlet that receives 4" SDR-35. We recommend adding 4" rubber no-hub couplings (quantity 2) for quick pipe connection to the filter outlets.
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.
