Question 1

Will my 21gal 2.5HP compressor work for this sprayer? cfm 4.7 @ 90psi and 5.8 @ 40psi

Accepted Answer

If I recall, the gun wants around 11 cfm flow to spray correctly. So what that means is you would be able to "burst spray" which means you can spray as long as there is air in the tank, but once you run out, you'd need wait for the compressor to recharge because your pump just won't be able to keep up. I can vouch for this as I have a 15.4 CFM 175 psi 60 gal quincy and it sprayed continuous no problem, but the pump was running quite a bit (it would cycle off for a few minutes, I'd say it was 5 min on 5 min off cycle). With a 21 gal compressor, assuming it's ~150 psi storage (keep in mind the max pressure just indicates the total storage capacity of the compressor), you'd probably get between 2 and 3 minutes of spray time. This will be true of any HVLP spray gun, not just this one. That's the HV part of the HVLP, high volume. So if you were just doing some spot repairs or small parts it might be ok, but if you tried to paint a fender or larger, you might run in to issues with re-charge time and flash time not lining up so you'd loose your wet edge waiting for air. Hope that helps.

Question 2

The picture shows 4 heads (1.2, 1.3, 1.4, and 1.8). The detailed description shows that it only includes 1.4 and 1.8 - What is really included?

Accepted Answer

Mine came with 2 each of the 1.4 and 1.8 heads.  I don't remember the picture showing what is displayed now.  When I ordered mine it only showed the two sizes of heads.

Question 3

What are the cfm and psi requirements?

Accepted Answer

10 cmf with minimum 5hp motor compressorl Also said more than 10 cmf is better. But remember that 4 + 4 + 4 = 12 That's your home compressor plus 2 of your friends that you borrow for a couple days. just tee them together and runyour hose from the filter/dryer cluster.3 into one and you have plenty of air.

Question 4

What size head would you use for cabinetry?

Accepted Answer

if the material is thin go with the 1.2 or 1.3 if thicker 1.4
