Question is what model for a home shop. Will mainly spray water bornes just not sure what is a good system. Do I need a 5 stage or is that overkill and expense.
I went back and forth on this when I bought my Fuji 4 stage. As I stated else where I didn't think the extra .5psi difference from a 5 stage was worth the premium and wasn't going to make any difference to me since I didn't know what I was doing anyway.
My Fuji is a good system, and even I can get good results with it as long as I don't try to spray heavy (viscosity) coatings without being thinned.
What kind of waterborne coatings will you be spraying?
While budget is always a consideration, I think that if you are planning on spraying primers and pigmented lacquers than get a 5 or 6 stage machine.
If you have read the posts on finishing there is really no one good tool for every application or coating type.
I believe more pressure is better than less and as long as the gun can handle the higher pressure, investing in a turbine that generates the highest psi at the gun gives you a lot more flexibility (speed) as well as a coating that is more evenly atomized than a turbine that generates lower pressure.
If you are only ever going to spray clear coats (ie. no primers or pigmented coatings) and volume/time is not an issue, then a good 3-4 stage turbine will work well.
For water borne spraying, look for a gun with Stainless steel fluid passages. If I was buying a gun (separate from a turbine) today I would look at an Accuspray 10G with a PPS.
Also get a whip hose if one is not supplied with your turbine. Because turbine hoses are large diameter they are heavy stiff, a whip will help make it easier to maneuver the gun and cool the hot air generated by the turbine.
Every ones requirements are different so if I was buying a system today I would probably buy a 5 (Apollo) or 6 stage machine because I believe I (should) be able to get a wider, more even spray pattern delivering more coating. Capspray makes a 6 stage HVLP turbine that delivers 11.5psi from the turbine.
Good luck. Spraying is a lot of fun both to learn and perfect.
