AirShootinest still thinks it's the GOAT. I have a 100 cu in tank and I know ToAuto suggest you not fill tanks BUT. What procedure would you use to fill this smaller tank? I thought, connect the compressor to the tank, start fan and then compressor with bleed valve open, open the tank valve and close the bleed valve. Run for 5 minutes while watching the temp. Open bleed valve on compressor and shut tank valve and, then turn off compressor and let the fans run for 5-10 minutes or until compressor temp is back to normal. Then turn on compressor, close bleed valve and open tank valve and repeat cycle. Does that sound about right? Are any A3 owners using it to fill tanks and what is your procedure? Thanks!
