Features

Senninger® has improved the i-Wob® design with the next generation i-Wob®2 for center pivot irrigation. Featuring a protective shroud that doubles as a nozzle carrier, the i-Wob2 can better withstand harsh operating conditions. Senninger Wobbler® sprinklers are recognized worldwide for their ability to spread water in a uniform pattern that is resistant to wind drift and evaporation.

Key Benefits

Ultra-low operating pressures save water, energy, and money.
Gentle rainlike distribution pattern over a large area reduces the impact of the sprinkler's pattern on the soil structure, allowing for a slower intake rate to help reduce runoff and wheel tracking.
Outstanding uniformity helps ensure consistent coverage for improved crop development and overall yield.

Advanced Features

Senninger Wobbler technology ―rotation of grooved deflector coupled with wobbling action― provides the most uniform water application in center pivot irrigation systems. Senninger Wobbler sprinklers distribute droplets with lower application intensity over a large coverage area at low pressures.

Wobbler technology for mechanized irrigation

UP3 snap-in nozzles are easy to remove for cleaning or changing. To remove the nozzle, simply pinch and pull, then place and click to re-install. There is no need to disassemble or remove the sprinkler.

The color-coded nozzles are highly visible and easy to identify. The nozzle numbers (corresponding to orifice sizes in 64ths of an inch) are visible on the ears, with half sizes denoted beneath the second digit and the notches on the lower edge of the nozzle.

*It is recommended that larger nozzle sizes be used only on soils that can handle higher application rates.
** Hunter Agricultural Irrigation recommends 0.69 bar for optimum performance; 0.41 bar can be used for nozzles #12 and larger.
*** For optimum performance, Hunter Agricultural Irrigation recommends the use of maximum spacing for 1-2 spans only.
Installation Requirement: Always mount the i-Wob2 on a minimum of 0.6 m reinforced flexible hose. The hose must be on the outlet end of any semi-rigid or rigid drop.
Keep i-Wobs above crop canopy when outlet spacing exceeds 3.0 m. This is especially important on high profile crops.
