Scuba tank for air gun blow tool / tire inflator

[Yellowdog]

I have restaurant equipment and one of the best ways of prolonging the refrigeration life is to keep the coils clean. I would to attach an air gun blow tool to my tank to use in routine maintenance in the restaurant. I think that I need a first stage regulator with the low pressure hose connected and then I can attach a blow tool to the LPH. Also I think I would be able to attach a tire inflator to the LPH. Maybe something like this . I don't want to use my first stage dive regulator inside, in a commercial environment, so I was thinking about buying a cheap one on ebay to use for my tools. Will this work or am I missing something. Thanks for any help.

Works just fine. I have an old first stage that is dedicated to such things as you describe.

A cheap one on eBay or a $49 diverite argon first stage from Dris.

Likewise, sometimes I carry an S50 with me in my 4x4 to inflate the tyres after driving in the desert.

The airgun is great for drying off my camera housing too

I use a Conshelf 1st stage and I backed off the intermediate pressure to conserve air. You don't need 145 psi to do what you ate doing. Most of the times 90-100 psi gets the job done.

I am assuming you do not have a second stage regulator attached and have a dedicated set up just for using compressed air. From a safety standpoint it is important that you attach a pressure relief valve in your first stage to prevent a hose or blowgun from exploding if you should have a first stage leak. I pick them up from time to time on the web for 10-15 bucks. I have seen a number of folks using set ups for inflating tires and airguns without that. It can be dangerous wothout a pressure relieve valve.

So use an actual 2nd stage dive regulator as a relieve valve?

I use a variation of your idea...works fine for tire inflation.

Or a separate over pressure valve: XS Scuba Over Pressure Valve AC395 with reviews at scuba.com

I picked one up to use on a Nemrod upstream second I was using old school, just the first and second. Had a hose blow on the same configuration, no relief, back in the day and adventure ensued.
