Automatic Self Cleaning Water Filters

Water Saving Filter Slashes Backwash Water By 90%

The V-Series units from Rain Bird provide efficient and reliable filtration, while conserving the amount of backwash water required. Due to its efficient rinse system, the V Series filter uses only 1 to 2 gallons per rinse cycle. This low flush volume makes it the ideal unit for a wide variety of applications. Designed for low flow applications, the unit is available with 3/4" and 1" inlet and outlet, to handle flow rates up to 27 gpm. The stainless steel fine screen is available in a variety of sizes to suit any application.

How It Works

Dirty water enters the inlet (1) into the center of the fine screen (2). The water then passes through the fine screen from the inside out and exits to the outlet (3).

The unwanted solids accumulate on the inner surface of the fine screen, building up a filter cake which filters out even finer particles, creating a pressure differential. Once the pressure drop reaches a preset level, a rinse cycle is activated by the control system, opening the rinse valve (4) to an atmospheric drain and closing the optional controlled outlet valve (C.O.V.) (5).

As a result, pressure drops in the hydraulic motor chamber (6) and the dirt collector assembly (7). The pressure drop creates a backflush stream, which sucks the dirt off the screen, similar to a vacuum cleaner. The backwash water is carried through the nozzles (8) and the direct collector tube before being ejected out of the holes in the hydraulic motor (9). The water being ejected out of the hydraulic motor causes the direct collector to rotate, similar to a sprinkler. In addition, the pressure drop in the hydraulic motor chamber forces the dirt collector assembly to move axially, controlled by hydraulic piston (10). This combination of movements ensures that the entire screen area is cleaned each cycle.
