20T (.020" dia. opening)
light/medium: less than 15 to 20 seconds in a zAHN 2 Cup,
e.g., stains, varnishes, thin lacquers, automotive refinishing materials
40T (.040" dia. opening)
medium: 20 to 30 seconds in a zAHN 2 Cup,
e.g., general industrial coatings
55T (.055" dia. opening)
Heavy: greater than 30 seconds in a zAHN 2 Cup,
e.g., low VOCs coatings
55T (.055" dia. opening)
■
All fluid nozzles use the 2s air nozzle.
■
The 2s air nozzle is recommended for siphon applications or pressure-assist applications.
For Binks Cub SL Spray Guns using pressure or pressure-assist, use nozzle 20T for light/medium
materials and 40T for heavier materials. use of larger nozzles or of very light materials with a
pressurized gun will result in excessive material flows and is not recommended.

Regulator pressures are based on 25' of 1/4" hose in good condition without quick disconnects or other
restrictive fittings. Gun inlet pressures are measured at the gun air inlet with the gun triggered. use
the Air Nozzle Test Gauge Accessory 54-4150 to confirm the atomizing/regulator pressure for your
actual air supply set-up. These recommendations are typical for average fluids, and are intended to
serve as a starting point. Adjust as necessary for your specific application. Regulator pressures for 5/16"
hose are 3 to 5 PSI lower.
