What is HVLP?

HVLP turbine motors produce extremely high volumes of over 100 CFM (cubic feet per minute) at very low pressures (3 - 8) psi (pounds per square inch). Compare this to a typical air compressor set-up of 45 - 60 psi at 8 CFM. HVLP turbines supply air at a much lower velocity producing a softer, easier to control spray. This allows you to lay the paint on gently and not blast it on. Benefits of HVLP include less overspray and less paint wastage. Transfer efficiencies can reach 85%, resulting in 30-50% savings on the cost of paint! The quality of the finish is identical to the best high-pressure spray finishes. In addition, the air from the Sprayfine® turbine is heated by a process called adiabatic heating, eliminating any moisture in the finish being sprayed, and speeding up the flash-off rate, reducing runs and sags!

In some areas of the USA (Southern California for instance), high-pressure spray systems are prohibited in certain industries. HVLP turbine systems automatically comply with all known regulations in North America.

Spray Pattern selection

Spray Pattern Shape:
The Spray pattern is adjusted by turning the ears of the air cap into either a vertical, horizontal, or diagonal position as shown below:



Spray Pattern Size:

To change the spray pattern size, screw the air cap ring in or out accordingly. Turning the ring clockwise will make the pattern bigger (and reduce the atomization). Turning the ring counterclockwise will make the pattern smaller (and increase atomization).


Material Flow Adjustment:

To increase the material flow, turn the adjusting knob on the back of the gun counterclockwise, to decrease the material flow, turn the adjusting knob clockwise

    Purchased the 4 Stage unit, Sprayed Benjamin Moore Advanced Latex on six panel solid doors/jams. Thinned paint and sprayed away. Very pleased with the finish product and great customer service. Highly recommend this HVLP 4 Stage Turbine.

    Perfect Finishing unit for Custom Woodshop

    Posted by Gary owner of Southern Woodshop on 13th Oct 2016

    Sprayed Conversion Varnish per manufacturers specs flawlessly, and precat Lacquer as well. Highly recommended. No Vibration from unit and not annoyingly loud like others.

    Good stuff!

    Working on initial perceptions and keeping a running log of how things go over at "www.woodworkerszone.com". So far, the A401 meets or exceeds my expectations for the price point. -- Fancy way of saying good value for the money.
