K-Rain Rotors
K-Rain rotors: gear-driven sprinklers for medium-to-large zones
K-Rain gear-driven rotors are the residential and light-commercial workhorse for medium-to-large turf zones. K-Rain's flagship, the RPS™ 75, covers a 22–51 ft radius range and a 40°–360° adjustable arc at 20–70 PSI, with twelve standard and low-angle nozzles included in the box. The riser drops into existing Hunter PGP and PGP Ultra in-ground cans, so the RPS75 is the standard retrofit when you're replacing an aging rotor without re-cutting the ground.
