Hunter’s revolutionary MP Rotators use multi-stream technology to deliver accurate streams of water with superior uniformity. When used in place of standard spray nozzles, it’s not uncommon to see system water use decrease by up to 30% or more. This technology and water savings are brought to life in the PRS40. This efficient watering tool combines the rugged Pro-Spray body and replaces the traditional nozzle with an MP Rotator. Regulated at 40PSI, the Pro-Spray PRS40 ensures the optimum output pressure to achieve maximum efficiency.
