This is an air tool question, not a boat question, but I know someone here knows the answer.
I have a typical compressor
in my shop, maintaining 125 psi. I use a little 5-gallon portable tank as a way to use air tools when dragging a long air line isn't practical. It's great for when I need to do a little paint
work or use an air tool that doesn't take a lot of volume, like my 18ga brad nailer, doing wood trim and moulding work. The 5gal of air at 125 psi will let me shoot 100 nails, easy. I have a regulator
on the tank. I usually run my HVLP paint
gun at about 40 psi and my brad nailer at about 60 psi.
Here's the problem. The portable tank has a simple tire-type inlet valve for filling. So, I have to use an inflator on my shop's air line to fill the tank. Takes a long time, and I have to hold it on there. I'm thinking, this tank also has a female quick connector for an outlet, where I hook up the tools. Why not simply make myself a little hose with male connectors on both ends? One end goes on the shop's compressor
, the other on the tank's outlet. It would speed the refilling of the tank way up, and I wouldn't have to hold it on there like the inflator. But if I did that, I would be filling the tank by pushing the air in through the regulator
Here's the question: Will I damage the pressure regulator by pushing the air into the tank backwards through the regulator? What if I open up the regulator so it's at the same 125psi level as the source while the portable tank's being filled?
Sorry to be so wordy. Thanks for your thoughtful replies!
