What makes ScreenGuard™ the leading screen filter in the industry?

• Bigger is Better. The largest filtration in the industry prevents more dirt and sand particles from entering your irrigation system, reducing the risk of clogging and sub-optimal flow rates.
• Grow with confidence. Gain greater peace of mind, knowing that your irrigation system is running at maximum efficiency.
• Less costly maintenance. By requiring less back-flush cycles, our screen filters save you time and money on routine cleaning and maintenance.
• Designed around you: From 4” all the way up to 10”, and with various mesh rating screens, you are sure to find the screen filter that suits your needs.
• Plug and play. Screen filters arrive fully assembled, keeping onsite preparation and set-up costs to an absolute minimum.
• Built to perform. The filter body is made with 2-layers of high-quality carbon steel that protects against rust, and the cover and piston are made from a durable anti-corrosion composite material.

Description of Operation

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.
