Using Fluid Set Charts
Turbine Spray Gun includes a #3 fluid set, Part No.
240113. The size of air cap, fluid nozzle, and fluid
needle are marked on parts.
Use fluid set charts on page 10 to order different size
fluid set or to find part number of individual
components of fluid set. Charts identify fluid sets used
in contractor and automotive applications.
Fluid sets include air cap (A), nozzle (B), and needle
assembly (D). See Fig. 11.
NOTE: To order other replacement parts for gun, see
parts drawings and parts lists for gun model on pages
20 to 23.

Setup
Selecting Fluid Set
Turbine spray gun fluid sets range in size to provide
different fluid flow rates. Selection charts on page 10
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.
To eliminate mist, use air cap one size larger than fluid
nozzle. Use of smaller size air cap produces finer
finish, but can increase mist.
For very fine finish work (automotive, furniture, etc.),
order air cap two sizes smaller than needle and nozzle.
0.5M mm or 0.7M mm multi-hole air caps are
D recommended for automotive finishes. See
Automotive Fluid Set Chart on page 10.
For narrow fan pattern (wood finishing), order
0.5W mm, 0.7W mm, or 1.0W mm narrow fan pattern
air cap. See chart below for part numbers.
