“E-Series” Electric Suction Scanning Screen Filter

High Performance Precision Scanning

Rain Bird E-Series Electric Suction Scanning Screen FilterRain Bird’s “E-Series” Suction Scanning Screen Filter provides worry free high-flow rate filtered water quality. Powered by source line water pressure and an electrical drive motor, the filter’s backwash system produces a concentrated high velocity reverse water flow to precisely clean the screen of any entrapped contaminants.

Unique to this design, Rain Bird has eliminated potentially troublesome limit switches (for reversing the drive mechanism) and implemented a reversing mechanism that is simple and higher in reliability than other units on the market today. Models are available as a filter unit only, or as a filter assembly including bypass plumbing and valves for fast and easy installation on site.


Dirty water enters the inlet flange (3) and passes through the coarse screen (1). The water then flows to the inside of the multi-layer fine screen (2) filtering suspended solids that are too large to pass through the screen. Clean filtered water then leaves the filter through the outlet flange (4). Suspended solids accumulate on the inner surface of the fine screen, eventually restricting the filter and creating an increasing pressure differential at which point a cleaning cycle is initiated. The controller opens the rinse valve (5) which quickly drops the pressure in the rinse chamber (6). Water moves from the nozzle opening, though the dirt collector (7) into the flush chamber and out the rinse valve (5). Self-adjusting nozzles allow each nozzle to lightly contact the screen surface for increased efficiency. The drive assembly (8) slowly rotates the dirt collector (7) in a tight spiral motion at a fixed speed to clean every square inch of screen. The reversing mechanism allows the dirt collector to oscillate back and forth as long as the uni-directional motor is operating. There are no limit switches to fail or multiple motor starters in the control box. The controller stops the drive assembly (8) when the screen is clean and closes the rinse valve (5) completing the cleaning cycle without interruption of system flow.

Monitoring and Controls

The standard Rain Bird control system consists of a programmable logic controller, a differential pressure switch, electric drive motor, and a solenoid actuated flush valve. The differential pressure switch monitors inlet and outlet pressures and comes factory preset to 7 psi. The housing mounted solenoid actuated flush valve and electric drive motor are activated by the controller when the differential pressure exceeds 7 psi. The filtration system is automatically monitored and controlled either on elapsed time since the last cleaning cycle or pressure differential (user definable). If timed cleaning cycles are utilized, the system will automatically default to a backwash based on differential pressure if a 7 psi differential pressure is reached before the next timed cleaning cycle. Standard Rain Bird automatic controls are available for 115 VAC and 230 VAC, 50 / 60 Hz (user-configurable) single phase power.

Note: “E-Series” filters integrated with a Rain Bird Pump Station utilize 115 VAC solenoids.


Rain Bird “E-Series” filters are built for years of durable, trouble-free service. The housing and covers of standard filters are made from thick wall high-grade, low-carbon steel. All exposed surfaces, both inside and out, are polyester powder coated over a zinc phosphate primer coat. Easy maintenance access to the internal components of the filter is through a removable front cover with handles that is se­cured to the front end of the filter housing. All wetted components are constructed of either engineered plastics or non-corrosive metals. All Rain Bird “E-Series” filters are also available in Stainless Steel construction, for the most demanding water quality applications.
