Raptor liner ??

[B.O.B.]

So I am getting ready to do my interior and want to do raptor liner inside. My question is how big of a compressor do I need? Was thinking of using the one at work but I wouldnΓÇÖt be able to drive it home. What did you all use?

Some guys on Cb.com recommend one that can maintain 50 psi and is at least 20 gal.

Do you know what tip is recommended for Raptor? My 20 gallon can do ~8 scfm at 40psi which works well for paint and primer. For primer, the 1.8 tip worked well but I doubt I could use a 2.0 without increasing my scfm. Also, I can only do a panel or two without having to stop to let the compressor catch back up. I also have 20' of pipe to help cool the air before it gets to the gun.

Not sure if that helps but it's what I've learned.

I've used 2 types of guns to spray bedliner. A drywall type hopper gun and a schutz gun. The schutz gun has an adjustable output. The Al's hopper gun says it has 3 tips 6mm, 8mm & 9.5 mm, can't remember which one we used.

I liked the schutz gun because it was much more precise & easy to control, but had to be refilled more often. You wouldn't want to run out of air because the liner will set up if it sits too long. It's a process that is very time sensitive. I did fine with my 5hp 60g single stage compressor with both guns, it's rated at 12.5 cfm @ 40psi.

Here is a decent page I found trying to find CFM ratings for schutz guns.

The gun that fits the Raptor cans, 40-60psi @ 5-6cfm:
