RKTS-490NSA – 4" Semi-Automatic Screen Filter for Large Commercial Irrigation Systems
The RKTS-490NSA is a 4" semi-automatic screen filter designed for large commercial agricultural irrigation mainlines and pump stations where continuous operation is required. Like other filters in the NSA series, the RKTS-490NSA supports in-service flushing — allowing the screen cartridges to be cleaned while the system remains fully operational, eliminating irrigation downtime for filter maintenance. The 4" MNPT connection serves high-capacity mainlines requiring large-diameter filtration at a single point.
Key Features and Benefits
- In-service flushing capability — semi-automatic design allows the filter to be flushed without stopping irrigation, ideal for large systems where shutdowns are costly or impractical
- 4" MNPT connection — handles large-diameter agricultural mainlines and pump station plumbing without flow restriction
- 120-mesh screen cartridge — standard filtration for commercial drip and micro-irrigation; polypropylene disc construction resists corrosion and chemical degradation
- Glass-reinforced polypropylene body — UV and chemically resistant for long-term outdoor use in agricultural environments
