Hunter SRM-04, Low Flow Rotor

The Hunter SRM-04 is Hunter’s shortest-range rotor. It is designed to offer a convenient and efficient alternative to spray heads. The Hunter SRM-04 is capable of working in tandem with larger rotors to combine big and small areas in a single zone. Utilizing the SRM-04 where appropriate, results in fewer sprinklers performing more efficient work at a more economical price.

The Hunter SRM-04 features a rack of six water-efficient nozzles. All nozzles can be easily identified by its flow rates. It can be installed and changed quickly and easily. This versatile rotor also includes a radius adjustment feature that fine-tunes the spray to keep water off driveways, walks, and other non-landscaped surfaces. It has an arc setting of 40 to 360 degrees. The Hunter SRM-04 hs six nozzle choices and a water lubricated gear drive.
