Turbo Flat-fan:

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

Pre-orifice

Exit orifice

New release in 2006:

• Dual outlet• Superior leaf coverage• Droplet range slightly larger that

comparable TT flat-fan

Turbo TwinJet

2nd Generation Venturi Nozzles:

• More compact• Larger drops• Operates at lower pressures• Percentage of fines do not

increase with pressure

3rd Generation Venturi Nozzles

Page 12: bae.ksu/faculty/wolf

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

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?
