Scuba tank to run air Tools / Bilge pump

[HappyMdRSailor]

OK...

Everybody's working on the tank supply deficiency .... which is good....

BUT... I've owned hundreds of air tools... Unless kept in a rather PRISTINE environment, they typically RARELY run up and work to optimum capacity when first picked up and connected to the supply...

Unless you are talking about an marine/dirty environment industrial motor made out of exotic materials the motor itself is going to be problematic too...

Buy a petrol powered pump if you are that worried. As others have pointed out, a scuba cylinder would only run a pump for a few minutes.

Also, very few scuba divers would ever use 100% oxygen on their tanks. This is solely used by divers who are doing deep dives and using to cut decompression times or add a safety margin. Using 100% oxygen deeper than about 7 or 8 metres will kill you!!! I would estimate that less than 0.1% of divers will ever use 100% oxygen.

By the way, I do know about these things, as of today I have done 3,730 dives, and on quite a few of these I have used 100% oxygen.

Hello all
I’d like some input on this..
I am wanting to take a high pressure air tank
With a reducer, and operate an air stapler .
Low psi 50-60 lbs but 5-6 shots a minute.

What pressure range and volume is your high pressure tank.

Greetings and welcome aboard the CF, Pete.

Based on a conversation years ago with a friend/commercial diver, ordinary air tools work fine from an air (not oxygen!) tank. The major trick involved was that he stored his air tools in plastic bags with cooking oil. Cooking oil doesn't have to biodegrade, it's already bio.

Perhaps more importantly, what are the volume requirements per shot for the stapler?

Pneumatic nailers are thirsty, small staplers, generally not so much. Bostich has finally started making an effective, reasonably low cost (less than 50 US), T50 electric stapler, available from the big box stores, that works really well for upholstery (I replaced the pneumatic one I used for recovering pool tables with one recently, don't know how long it'll last, but it works as well as the one it replaced), if that is your end use.

It's 110vac, so you'd need a low-wattage inverter to run it from battery power.


And to answer the original, unanswered question, sure, they're called air-operated diaphragm pumps. Also, like framing nailers, very thirsty indeed...

I used to do this often but have mostly gotten rid of my air tools.


Most first-stage SCUBA regulators are set up for 120 PSI output. Many older ones are easy to adjust without disassembly. Conshelf XVI are readily available on ebay and are fine for that though most need service, new hoses, and a new high-pressure gauge. If you have extra parts around you can scrounge together something that will work. There is plenty of gear that is good enough for air tool use but is no longer safe for diving.


A typical scuba cylinder is 77 cubic feet and you can use almost all that before the pressure drops too low. Typical pancake air compressor is maybe 2-3 cubic feet per minute so think in terms of getting the equivalent amount of air to what you would get from a pancake compressor running for half an hour.


But I got rid of all my air tools


The battery tools are so good now that I don't need air. Milwaukee makes battery powered nailers and staplers. I have their battery inflator which is great for tires and things like fenders


So the only thing I use the scuba tank for (other than diving) is blowing the dust out of inaccessible places.
