Maximum | 15 psi | 15 psi | 15 psi | 15 psi |
*It is recommended that larger nozzle sizes be used only on soils that can handle higher application rates.
** Senninger recommends 10 psi for optimum performance; 6 psi can be used for nozzles #12 and larger.
*** For optimum performance, Senninger recommends the use of maximum spacing for 1-2 spans only.
Note: Always mount the i-Wob2 on a minimum of 2 ft 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 10 ft This is especially important on high profile crops.
