is HVLP and LVLP
- High Volume/Low Pressure
systems allow larger amounts of material to be delivered at lower pressure. These
systems deliver air generated by a turbine to the spray gun via a flexible hose.
The spray gun takes the high volume of air and reduces it to 4-10 psi (pounds
per square inch) at 46-62 cfm (cubic feet per minute) allowing an even flow of
the material with very little over-spray. The spray pattern of the HVLP gun can
be set by adjusting the air cap in or out, thereby providing the amount and/or
the fineness of the spray.
turbine is similar to a vacuum cleaner motor. Turbines are rated by stages, or
the number of fans they have. There are typically two to four stages. The fans
operate at about 20,000 rpm. Turbines are normally smaller than compressors and
weigh considerably less.
guns have larger passageways than compressor guns and airbrush guns. This is needed
to accommodate the high volume of material passing through the fan under lower
of Rays LVLP - Low Volume/Low Pressure
HVLP, an LVLP system is turbine driven (1-stage), but it operates at 1 psi pressure
at the gun with 41 cfm. The fine spray is quick drying and has very little over
spray. LVLP was designed specifically for applying tanning solutions and exfoliants.
The HVLP gun is the same as with HVLP systems to give you the spray pattern options,
cool grip, material flow adjustment, and trigger adjustment. It takes approximately
5-10 minutes to spray an entire person in comparison to airbrushing which takes
approximately 35-50 minutes.
