Selecting the Proper Nozzle Size
Follow your material suppliers recommendations for
proper nozzle size. In general, use the smaller nozzle
sizes for low flow rates or light viscosity materials and
larger nozzle sizes for higher flows and higher viscosity
materials.

The spray guns were designed to produce the highest
quality finish with today’s automotive paint systems.
The HVLP and Compliant guns typically utilize 29 psi
(200 kPa, 2.0 bar) inbound air pressure to produce
high quality paint finishes and comply with environ-
mental regulations.
The air regulator must have a minimum air flow
capacity of 30 scfm at 100 psi (0.7 MPa, 7 bar) air
pressure.
Ventilate the Spray Booth
WARNING
To prevent hazardous concentrations of
toxic and/or flammable vapors, spray
only in a properly ventilated spray booth.
Do not operate the spray gun unless
ventilation fans are operating.
Check and follow all of the National,
State and Local codes regarding air ex-
haust velocity requirements.
Check and follow all local safety and fire codes.
