Hunter MP Rotator Adjustable Rotary Nozzle 8' - 16' | MP81590

• Spray Radius: 8 ft to 16 ft Adjustable

• Spray Pattern: 90° - 210° Adjustable

• Flow Rate: 0.42 ”“ 1.30 GPM

As the newest member of Hunter's popular MP800, the MP815 extends a 0.8"/hr (20 mm/hr) matched precipitation rate to a convenient larger maximum radius of 16' (4.9 m). Thanks to this capability, the MP800 offers increased system-level design and retrofit applications.

The previously released MP800SR covers distances as short as 6' (1.8 m). Now, with the addition of the MP815, the MP800 can irrigate spaces up to 16' (4.9 m) with uniform coverage and the same 0.8"/hr (20 mm/hr) matched precipitation rate.

Hunter is the only company to offer three matched precipitation rate options for pop-ups, giving customers more choices for irrigation management. To maximize water-use efficiency, choose the standard MP Rotator, which has a slow precipitation rate of 0.4"/hr (10 mm/hr). This is perfect for tight soils, as well as steep slopes to eliminate runoff. Use the 0.8"/hr (20 mm/hr) precipitation rate of the MP800 for medium-grade soils, gentle slopes, and small spaces.

Both the standard MP Rotator family and the MP800 maintain all the benefits of the MP Rotator's patented design. Slow rotation of the nozzle allows for strong, wind-resistant streams that cover their full targeted range with a high distribution uniformity. For increased reliability in the field, the unique double-pop feature prevents debris from entering the nozzle, and with only one moving part, the MP Rotator is built for durability in even the toughest conditions.
