Groundwater or harsh water can pose a real challenge to the operation of your irrigation system. Screenguard was designed with the largest filtration area in the industry. A bigger screen means less cleaning cycles and enhanced system longevity. Screenguard offers uncompromized filtration operation with the most efficient self cleaning mechanism saving you labor and protecting your irrigation system.
Screen filters are highly recommended for irrigation using poor quality water, for heavy-duty usage, and in the following conditions:
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 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.
