Hiya,

the system i use, filters air and blows it out onto the body and is almost dry when it comes into contact with the body...........the HVLP doesnt have the same filtration and basically it sucks air in from aound your enviroment ie salon or wherever you are doing the spray tanning and then blows it out onto the body, so if you have a warm salon then it will be warm, its usually the liquid which needs to be cool otherwise it may de-stabalise, so thats why you may feel like its cool air coming out.

I personally dont like the HVLP sprayers for proffesional use, but each to their own........
