ScreenGuard™ Automatic Screen Filters

A three-layer stainless steel screen ensures long life and high performance. The ease of maintenance and externally mounted backflush valve are additional features.

ScreenGuard™ Automatic Screen Filters make sure your irrigation system is always protected and running smoothly. The 3-layer stainless steel screen can handle even the harshest water and is built for long life and high performance. These filters use a small volume of water to clean the screen with NO interruption to the system flow. ScreenGuard filters are the best choice for primary filtration for row and permanent crops.

Description of Operation

 

ScreenGuard Operations Image

A coarse screen protects the finer screen from large particles and it can be periodically cleaned manually. Automatic flushing of the fine screen is activated once the pressure differential (∆P) in the filter reaches a pre-determined value. During the flushing cycle, the backflush valve opens, pressure is released from the piston and debris laden water is discharged through the backflush valve. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered causing the dirt collection nozzles to move along and rotate cleaning the whole internal screen surface. The flushing cycle takes 5 seconds. The backflush valve closes at the end of the cycle, pressure is reapplied, moving the nozzles back to their resting position and the filter is cleaned. During the whole process, water supply is uninterrupted.
