We use both the red ones sold by Cleaveland, and the blue ones sold by Harbor Freight. We leave the air on 80-90 as we are using the air drills often, and they work best there. Never had a problem with either on several RV-12 builds. BTW, the HF unit is a great value!

I've been running mine at about 60 psi and it seems to pull the rivets just fine. Is there an advantage to running a higher pressure? Mine is rated up to 90 psi.
Excellent advice.. . . "And after pulling many airplanes worth of rivets in our shop, we have found that when high pressures are used the stem on a rivet will occasionally break prematurely.
Using lower pressures causes the river to set slower and prevents this. It also helps prevent bouncing the tool when the stem breaks (can cause scratches or worse).
For this reason we use ~60 psi and recommend that to others as well." . . .
