Turbine spray gun fluid sets range in size to provide dif-
ferent fluid flow rates. Selection charts on page 8 show
recommended combinations based on fluid viscosities,
flow rates, and usage.
As a general guideline, use fluid nozzle that will give
required flow with needle fully triggered at lowest fluid
pressure.
For low flow rates or light viscosity fluid, select smaller
nozzle sizes.
For high flow rates or high viscosity fluid, select larger
nozzle sizes.
Graco offers six different fluid sets:
WARNING
Do not exceed gun’s 50 psi (0.35 MPa, 3.5 bar)
Maximum Fluid Inlet Fluid Pressure and 10 psi
(0.07 MPa, 0.7 bar) Maximum Inlet Air Pressure.
Higher pressures can cause parts to rupture and
result in serious injury or property damage.
