Netafim MegaNet Red Sprinkler Head, 24° Trajectory
Big open blocks with wide head spacing get the most from a large nozzle and a long, high throw. This head is Netafim item 63600-004500, model MGN24D-330HO, identified by its red cap. The 3.68 mm nozzle flows a nominal 3.30 GPM at 33 psi. A high 24° trajectory carries that volume out across field crops, vegetables and orchard rows. Two matched jets turn the turbine in balance, so the head runs steadily through long sets. The drops stay gentle close to the head, protecting the soil surface from grooving. An integral filter at the inlet holds back particles that could block the nozzle. Its pop-up cover lifts only under pressure and closes again to keep insects out. UV-protected materials resist sunlight, fertilizers and agrochemicals over many seasons. The 1/2 in male thread fits solid-set risers and removable field stands.
Sizing Zone Flow Around the Red Nozzle
Each head draws about 3.46 GPM at 36 psi and about 3.79 GPM at 44 psi. A block of ten heads therefore needs roughly 35 to 38 GPM from the pump at those pressures. Size the mainline and laterals so every head still sees 29 to 44 psi under full flow. On a 33 x 33 ft grid the red nozzle applies about 0.31 to 0.34 in per hour. At 33 x 39 ft it applies about 0.26 to 0.28 in per hour. Those rates suit fast refills on sandy ground and short cooling cycles over fruit trees. Where soils take water slowly, shorter run times avoid runoff at this rate. Filter river or pond water to 40 mesh, and add a hydrocyclone for sandy wells. When the turbine wears, the gray replacement is part 63620-002100. Put the black locking pin back after service, since it holds the cover and turbine in place.
