Compressor-wise, those screw type are just such a sweet product, I've been holding off in hopes they will become more common. The body shop I was with (Matt & Dale were through) had a early high end industrial duty compressor- about the size of a photo copier (remote tank) and only a bit noiser, and output that was overkill for a 25 employee body shop. I've seen the home-shop-size screw type in catalogs (Gregg's, IIRC) but never priced one. I'm sure the price'd be enough to chill my enthusiasm quite a bit.
In Aus and New Zealand, they use some type of return hose on many tools. Not sure how that works (It's all about pressure differential...
, so anything that loses that.... dunno), but apparently it does- quieter and
significantly less air compressor output required for certain tasks...other tasks are obviously total loss. When I posted a reference to that on the GRM forum, someone recognized what I was talking about- some shop in the US a poster was familiar with, had set themselves up with that as a trial.
Some paint guns are worse than others- early HVLP were huge air hogs. Iawata has LVLP, Sata has what they call RP (Reduced pressure), and most brands are pushing what are referred to as Compliant guns, which mean they meet an actual material application efficiency rating California has had for a while and the US federal rule for a long time, while not actually operating below the Low Pressure limit (10 or 15 psi, I forget) that would've allowed them to call the guns HVLP in advertising. BTW, funny thing with HVLP guns is that they spray best at half again the pressure the advertising rates them at, even the name brands...
FWIW, We're actually the last "western" country to use essentially unlimited solvents and spray technology- through we are in the last 18 months or so of that. Anyway, the trend -at least with the name brands- was to lower air consumption, in some cases by a lot. The Iwata LVLP's were noticeable for having no "hiss" in use.
