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.
