NOTE: SOME MODELS HAVE BEEN DISCONTINUED. PLEASE CONTACT FACTORY FOR AVAILABILITY. IMPACT SPRINKLERS NELSON. BUILT STRONGER TO LAST LONGER! There’s a very basic reason behind the popularity of Nelson Impact Sprinklers. Our impacts offer a number of exclusive features and advantages which give better performance and longer life with a minimum of maintenance. Some of these features are pointed out in the illustration to the right. Large impact surfaces for consistent long life drive Stainless steel arm spring and pin Rugged Double Bridged We also go a bit further than most in testing and quality control. For instance, 100% of Nelson Brass Impact Sprinklers are individually water tested at the factory. When it comes time to select the right sprinkler to fit your needs, Nelson offers a complete line of impact sprinklers — both high and low angle — available today for agricultural use. They’re shown and Accepts Nelson FCNTM Flow Control Nozzle or standard Full throat water passage for best coverage Optional non-clogging vane for increased diameter of throw at higher operating pressure Extended life bearing for longer wear IMPACT SPRINKLER NOMENCLATURE F = Full Circle S = Single Nozzle F = Full Circle P = Plug in Second Nozzle P = Part Circle A = Low Angle V (not shown) = Vane L = Low Angle W = Wedge Drive F = Full Circle AA = Low Angle, Double Nozzle Nelson Irrigation Corp. 848 Airport Rd.

L20W PERFORMANCE DATA Wedge drive gives an extra “kick” for more driving power and improved impact sprinkler performance at lower pressures using smaller nozzle sizes. Pick the low trajectory angle (5°-15°) you want for under-tree use and for better wind-fighting ability. *MODEL L20W (Full Circle) — 5° TRAJECTORY — MAX. STREAM HT. IS 1.0’ ABOVE NOZ.

L20-04 PERFORMANCE DATA Low angle for better wind-fighting ability. Ideal for under-tree orchard systems. Available in trajectory angles from 5°-15° in 2° increments. Trajectory angle is built into the brass body for better hydraulic flow and maximum distance of throw. Accepts Nelson FCN® Flow Control Nozzle to equalize flow rate under fluctuating pressures. L20-04T is the same sprinkler as the L20-04 except it has a 3/4” bearing. Designed primarily for use on center pivot systems. Performance data is identical to L20-04. *MODEL L20-04 (Full Circle) — 5° TRAJECTORY — MAX. STREAM HT. IS...
