The Hunter SRM-04 is Hunter's shortest-range rotor and a smart, economical alternative to fixed spray heads. Its proven water-lubricated gear drive delivers steady rotating streams over a radius of 4.3 to 10.7 m at the recommended pressure of 1.7–3.8 bar (operating range 1.4–7.0 bar), with a precipitation rate of approximately 11 mm/h. The arc is fully adjustable from 40° to 360°, and the radius can be reduced by up to 25%, so you can tailor coverage precisely to small and medium lawns and planted areas. Eight interchangeable nozzles are available (0.50 to 4.0 GPM) and the unit ships with a factory-installed 2.0 nozzle. With its ½" inlet and compact 10 cm pop-up body, it works neatly alongside larger rotors in mixed-area designs. Sold as a single unit, without check valve.
