Roof Top Rainwater Harvesting Self-cleaning filters Rainy FL-500, When the rainwater along with dirt & debris flows by gravity through the down take pipes, it enters into the filter and starts rotating in anticlockwise direction at the periphery of the upper housing, this enables it to flow into the SS-304 filter element placed in the lower housing in angular motion at specific speed & velocity, which creates cohesive force at low intensity & centrifugal force at high intensity of rainfall. In both situations, involving low & high intensity of rainfall, the working principle of the filter based on cohesive & centrifugal force respectively, aids the filter element to flush out dirt & debris automatically. The water then passes through the drain outlet and simultaneously diverts clean water into the sump/ recharging well through the clean water outlet, which can be used for reutilization or recharging of groundwater source

• Filter Pipe connections can be turned 360 Degrees
• The filter efficiency remains unchanged even with the variation of rainfall intensity
• No consumables required
