WIDE RANGE OF OPERATION.
LOW PRESSURE.
SELECT FROM 2 NOZZLE TYPES:
The most economical selection, for use where fluctuating pressures are not a problem. Due to induced turbulence
created by the hydraulic design, droplet breakup is better with the F44AAB than conventional sprinklers, allowing
its use at lower pressures with standard nozzles.
®
Recommended for systems where field elevation differences or variations in pump pressure cause uneven water
distribution. The FCN maintains a constant flow rate, improving uniformity, reducing pumping costs and saving water.
RECOMMENDATIONS:
·
Any combination of nozzle sizes listed can be used on the drive
nozzle and secondary nozzle sides. Any nozzle listed can be used
on the drive nozzle side with a plug in the secondary nozzle side
(use Model 3RN Plug).
·
Nelson Irrigation Corporation specifically makes no representation
as to the suitability of any nozzle for a particular situation regarding
droplet size, uniformity, or application rate.

The Model 4V stream straightener vane will fit both the drive nozzle
and secondary nozzle sides and is recommended for high pressure
operation (over 60 PSI) to reduce stream breakup and increase
throw distance.
