Primary Application
The patented U-Series nozzle is the first plastic nozzle
with a second orifice* for close-in watering and more uniform water
distribution. Its unique patented design cuts watering times, saves water and
money, and reduces waste. U-Series nozzles fit all Rain Bird sprinklers and
shrub adapters and can be used with new and improved PCS screens.
Features
- Additional orifice for close-in watering.*
Minimizes dry brown spotsaround spray heads.
- Better, more uniform water distribution. Water
flowing from both orifices* combines to form a continuous water stream.
Eliminates watering gaps for more uniform coverage throughout theENTIRE
watering area.
- Lowest Scheduling Coefficient for most efficient
watering.**
No need to overwater the entire watering area to make sure the dry sections
get the water they need. Reduces watering times. Saves water and money. Cuts
waste.
- Matched precipitation rates between sets.
Matched flow (GPM, m3/h and l/s) and precipitation rates with all
1800 Series MPR nozzles. Provides flexibility in design and installation.
- Finer mesh screen protects bottom orifice from
debris.*
- Fully adjustable flow and radius accommodate
different area shapes.
- Five-year professional
customer satisfaction policy.
- Fits all Rain Bird sprinklers and shrub
adapters.
* Not applicable for single orifice full-circle
nozzles. These nozzles form larger water droplets with a lower trajectory
which resist wind and eliminate watering gaps for more uniform distribution.
** Scheduling Coefficient (SC) measures spray head
efficiency. SC measures how much more an ENTIRE area must be watered in order
for the driest sections to receive sufficient water. The lower the SC, the
better the spray heads distribute water. The higher the SC, the more the
entire area must be watered (and most of the area will be over watered) so the
driest spots can get enough water.
