How to tell if a sprayer is HVLP or not?

Hi all,

I'm just getting into painting...and trying out some things before I start spending hard earned cash.

I have a gun...here's the link to it:

I sprayed a 1 part plolyu on my dad's outboard engine and cover. Went pretty well, but now I'm about to start a major project painting my 36ft boat (will be using a 2 pt poly - Imron likely).

So my question is...how can I tell if this gun is a conventional air or a conversion HVLP? Finally, does conventional air sprayers use less CFM (ie, a smaller compressor requirement) than HVLP?

Thanks for all your help!

if your cup is on top (gravity fed) its an hvlp,,if under or if de-tached pressurized cup its conventional,,atomizer and that is better for boat paint,,but your tip is the important part,,finer the better,,,,,to a point,and a hvlp takes less air,,High Volume Low Pressure

Thanks for the reply. However, now I'm confused. Right now I see HVLP setups that have the cup under/detachable (not on top/gravity)....so this confuses me more.

"the1much" is wrong, wrong, wrong, wrong, wrong. The Devilbiss Plus, Iwata W400LV and the Sata RP3000 are all examples of non-hvlp gravity fed guns.
