As the newest member of Hunters popular MP800 Series, 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 Series offers increased system-level design and retrofit applications. Both the standard MP Rotator family and the MP800 Series maintain all the benefits of the MP Rotators 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.
