:huh: hi GUYS I NEED TO NOW WHAT CFM I NEED FOR A DEVILBIS gti w I DO NT THINK MY COMPRESSOR IS UP TO IT, I HAVE PLENTY OF PRESSURE-9 BAR 120 -120 PSI
Depends witch cap you are using the hvlp cap uses much more air than the compliant cap
with the 2000 aircap…
Air Flow: 12.5-16.0 CFM @ 30 PSI Inlet (from Devilbiss)

Hes in the UK so it would be the 115 aircap. it consumes 16cfm which is alot. I would consider the 110 aircap as it will take less air.
PSI or BAR doesn’t equate to CFM. One is a measure of pressure and the other is a measure of volume. The guns need more volume than pressure. You will have to check your compressor and see how much CFM it will put out.
i mentioned gti air caps in another thread

High Volume is refering to the volume of air the gun requires to be able to produce desired results from lower spraying pressures.
Therefore HVLP guns have larger CFM requirements than reduced pressure (compliant) or conventional guns. Meaning
THEY USE MORE AIR110 air cap 1.3 nozzle.if you are using lower air pressure,then you dont need so much air .hvlp are great for compressors that have a lower air out put than conventional guns.Friend OF MINE USES A nr92 SATA HVLP AND it does not run the compressor down ,as a conventional gun.

:blink: :blink:
link showing sata 4000 hvlp air consumption usage 430Nl/min or 15.2 CFM http://www.sata.com/index.php?id=satajet4000bhvlp&L=11
Sata 4000 RP air consumption 285 Ml/min or 10.1 CFM http://www.sata.com/index.php?id=satajet4000brp&L=11
How come the HVLP requires more air than the more conventional RP ?
even requires more air than the conventional high pressure SataJetB which uses 370Ml/min or 13.1 CFM http://www.sata.com/index.php?id=satajetb&L=11
what part of HIGH volume low pressure dont ya understand pot :stoned :stoned :stoned

Maybe getting confused and thinking of LVLP.
HV stands for high volume for a reason
[quote]HVLP (High Volume Low Pressure)This is similar to a conventional spray gun using a compressor to supply the air, but the spray gun itself requires a lower pressure (LP). A higher volume (HV) of air is used to aerosolise and propel the paint at lower air pressure. The result is a higher proportion of paint reaching the target surface with reduced overspray, materials consumption, and air pollution. A regulator is often required so that the air pressure from a conventional compressor can be lowered for the HVLP spray gun.
A rule of thumb puts two thirds of the coating on the substrate and one third in the air. True HVLP guns use 8–20 cfm (13.6–34 m3/hr), and an industrial compressor with a minimum of 5 horsepower (3.7 kW) output is required. HVLP spray systems are used in the automotive, marine, architectural coating, furniture finishing, scenic painting and cosmetic industries
[/quote]YOU are all right, i am wrong ,all the time i have been spraying for 35 years i though that volume was the amount of paint.in them years the question has never came up .Just shows you does not matter how long you have been spraying things will trip you up.

Well done takes a man to step back and admit he is wrong.
We are all wrong from time to time, it is what makes us human
:cheers thak you all again you are the best. richard
