Tip Sizes for Mini Spray Guns
My question is: What size tip would be equivalent on a mini HVLP gun? This is for spraying stringed instruments with a smaller compressor, and I don't need a full-size gun. In fact, I'd actually prefer to go to the mini for the lower air consumption and the potential for finer detail work.
From contributor D:
It's a little hard to answer your question and doubly hard since waterbornes vary so much in viscosity. The mini Astro with the 1.2 should do the job just fine and the Mini Astro with the 1.0 might do the job depending upon the viscosity of the waterborne that your using.
Generao Finishes' Pro Acrylic goes through the 1.0 just fine. Fuhr's waterbornes are a bit too thick for it and require the 1.2. Lacquer is lacquer, but with waterbornes there is so much variability. The beauty of the Astro however is that extra needle/nozzle sets are not very expensive. Nobody has ever said that for the SATA.
A new development on the MiniJet front is that SATA has released a 1.4mm nozzle set for the MiniJet 4. I'm using this to paint urethane bumpers on cars as it puts out a fair amount of paint.
The best recommendation is to measure the viscosity of the material and then call DanAm (the American SATA distributor) and provide them with that information and let them make a nozzle recommendation.
