RKTS340NSA – 3" Semi-Automatic T Screen Filter, 120 Mesh

The RKTS340NSA is a 3" semi-automatic inline screen filter designed for commercial irrigation systems where frequent manual maintenance is not feasible. The suction nozzle cleaning mechanism and built-in pressure differential indicator work together to alert the operator when the screen requires flushing, then purge accumulated debris through the flush outlet. The 120 mesh stainless steel screen provides drip tape, micro-sprinkler, and emitter protection (125 micron openings) across a 129.0 in² filtration area. Rated to 145 PSI.

Key Features and Benefits

  • Suction Nozzle Self-Cleaning – Reduces labor and downtime by flushing accumulated debris from the screen without full system shutdown.
  • Pressure Differential Indicator – Visually signals when the screen is approaching blockage so operators can initiate flushing at the right time, not on a fixed calendar schedule.
  • 120 Mesh Stainless Steel Screen – Suited for drip tape, micro-sprinkler, and emitter protection (125 micron openings), protecting downstream emitters and nozzles.
  • 129.0 in² Filtration Area – Large screen surface extends intervals between cleaning cycles.
  • 175 GPM – Sized for 3" commercial mainlines.
  • 145 PSI Pressure Rating – Suitable for high-pressure mainline supply in farm and municipal irrigation networks.
  • Replaceable Cartridge – Compatible with RKTS340-CART80, RKTS340-CART120, RKTS340-CART150.
