2 Nozzle Design Update Robert E. Wolf Extension Specialist Application Technology Biological and Agricultural Engineering

3 Nozzle Technology…… Nozzles designed to reduce drift Improved drop size control Emphasis on ‘Spray Quality’

4 Nozzle Efficacy/Drift Slope XR, TR Turbo Flood Turbo TeeJet Air Mix AI XR GuardianAir AI Ultra Low Drift Turbo Drop TTI Extended Range Chamber Design Venturi Design - I Venturi Design - II Nozzle development timeline

5 Nozzles Types? Flat Spray Patterns

6 Extended Range Flat-fan:

7 Turbo Flat-fan: l Turbulence chamber as in the Turbo Flood l Tapered edge, wide angle flat pattern l Designed to work in flat-fan nozzle holder l Uniform spray distribution, 50-60% overlap l Wide pressure range, 15 – 90 psi l Large, drift resistant droplets l Plastic with superior wear characteristics Pre-orifice Exit orifice

8 New release in 2006: Dual outlet Superior leaf coverage Droplet range slightly larger that comparable TT flat-fan Turbo TwinJet See Page 10, TeeJet Catalog 50A

9 Pre-orifice Venturi Nozzles(1 st generation) Pre-orifice Air induction Exit orifice Mixing Chamber

10 2nd Generation Venturi Nozzles: More compact Larger drops Operates at lower pressures Percentage of fines do not increase with pressure Turbo Injection - TTI See Page 11, TeeJet Catalog 50A Turbo TwinJet Induction AITTJ60

11 3 rd Generation Venturi Nozzles

12 New release in 2007: XR outlet with venturi air aspirator design More compact than AI style 2-piece with removable pre-orifice AIR INDUCTION XR TeeJet See Page 14, TeeJet Catalog 50A

13 GuardianAir Induction: More consistent droplet All-in-one cap and screen Wide angle with 15 degree incline toward the rear Aim forward or rearword – alternate? GuardianAir See Page 16, Hypro Spray Tip Guide
