The Saturn IV gear-drive rotor is engineered specifically to water landscape areas which require a throw distance of up to 25 ft. between sprinkler heads. Its arc is adjustable from 40 to 360 degrees in precise increments, which gives you the ability to aim it so that the water hits the landscape only and avoids any hardscape surfaces. The 4-in. pop-up height ensures that the nozzle clears tall grass. It comes with a pre-installed 2-gallon-per-minute (GPM) nozzle which results in a full-pattern precipitation rate of 0.30 in. per hour at 25-ft. square spacing at 40 PSI. This very low rate reduces the risk of runoff or puddling for many soil types and conditions.
It also includes a matched-precipitation nozzle rack with 0.5, 1.0, 1.5, 2.0, 3.0 and 5.0 GPM nozzles featuring a unique keyway design to ensure highly uniform close-in and far-out watering. It includes a radius adjustment screw which allows you to reduce the rotor throw down to 75% of its rated distance. It also includes a bottom inlet filter which helps prevent clogging of the nozzle. The can and riser stem are made from high impact ABS and metal components are made from stainless steel.
Adjustment of both the radius and arc requires the included gear-drive rotor key. The inlet is 1/2-in. female pipe thread (FPT). The state-of-the-art approach to mounting a Saturn IV is on a 1/2-in. male pipe thread (MPT) Blu-Lock combination swing joint, although it is compatible with 1/2-in. MPT Funny Pipe fittings, swing fittings and risers. The Saturn IV replaces rotors from Orbit, Hydro-Rain, and other major brands. Recommended operating pressure is 40 PSI. For outdoor irrigation use with cold water only.
