WARNING
Do not exceed the gun’s 50 psi (0.35 MPa,
3.5 bar) Maximum 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.
Turbine spray gun fluid sets range in size to provide
different 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:
Fluid Set Part Number Orifice Size (inch)
#2 244123 0.032
#3 244124 0.051
#4 244125 0.071
#5 244126 0.087
#6 244127 0.098
