TURBO TURFJET TIPS
This is a wide-angle (110°), hollow-cone, drift-reduction nozzle. Replaces conventional flooding nozzles in broad-
cast applications.
FEATURES:
• Color-coding makes it easy to match nozzle flow rates for easy identification.
• Color-coding is available in sizes 1 /
4
TTJ02-VS through 1 /
4
TTJ15-VS.
• Uniform spray distribution.
• A large orifice opening and passages minimize clogging.
• The Turbo TurfJet nozzle’s patented design element, a secondary swirl chamber in the nozzle cap, alters
the swirling action of the liquid so that the fewer driftable lines are discharged from the secondary orifice.
• Spraying Pressure 25-75 PSI (1.5-5 bar).
NOZZLE TILT
Delavan’s extensive research on spray patterns has proven that a tilt of about 45° for flood Nozzles or tips will
significantly improve the spray pattern uniformity.
The nozzle tilt reduces the effect of boom height variation and allows the spray nozzle to maintain a more fully
developed pattern even when the nozzle outlet is below the recommended height for the best spray pattern uni-
formity.
RECOMMENDED OVERLAP AND NOZZLE HEIGHT
Adjust spray height in the field to overlap a minimum of 30% of each edge of pattern. Adjust nozzle height until
this is achieved. If a decision to tilt the nozzle is made, do it before measuring the width of the spray on the
ground and adjusting nozzle height. See example below.
