4.3 Using The 7500 AtomiZer With A Turbine System
After set up of spray gun is complete:
1. Connect the air hose to the male air quick connect (#27, page 33) located at the
bottom of the spray gun handle.
2. Connect the other end of the air hose to your Turbine.
3. Turn on your turbine. Make sure air is always coming out of the air relief
mechanism. (If external).
4. You are ready to spray and apply coating to your work, follow general spraying
instructions.
4.4 Using The 7500 AtomiZer With Compressed Air
Be sure air lines are clean, moisture and oil free. Drain any in-line filters. Be sure the compressor you are using will maintain
continuous air (flow pressure) to continuously supply the spray gun. Generally a 3hp air compressor with a 20 gallon (75
liter) tank will maintain continuous air at 13PSI - 19PSI (0.9 Bar - 1.31 Bar). A larger compressor might be necessary if
spraying high viscosity materials at higher PSI. Set the regulator to the spray gun as follows: 6 PSI - 12 PSI (0.414 Bar - 0.83
Bar) for thin, low viscosity fluids. 13PSI - 23PSI (0.9 Bar - 1.59 Bar) for medium to high viscosity fluids.

* All tests performed with Material Screw open 2 full turns, full trigger pull and 3/8” x 20’ air hose with high flow fittings
from wall regulator forward. High flow fittings only reduce the sealed pressure needed to achieve 10PSI at the air cap, but
does not reduce the amount of inlet flow pressure needed to achieve 10PSI Air Cap pressure. Pressure’s quoted are flow
pressures, sealed pressure’s will vary depending on the size of your air compressor and any restrictions in the air lines.
Use these settings as a guideline. Always use the lowest pressure that produces the best atomization and visual results.
This will provide the highest efficiency and lowest overspray. You are ready to spray. Follow the general spraying directions
for the best operation of your spray gun. For further assistance please visit our website at www.hvlp.com or call our customer
