nitrogen for air tools

CO2 stores as a liquid at reasonable temperatures and pressures, so you get a whole lot more gas volume out of a reasonable sized tank. As long as you don't try to do something stupid like run a sandblaster at 15 CFM for 10 minutes straight, the regulator should not freeze up due to the liquid to gas transition. If your trailer can be sealed up tight, you should be careful to provide some ventilation if you use either CO2 or Nitrogen inside the trailer. Both are safe inert gases, but both can displace oxygen from the space you are attempting to occupy, leaving you to asphyxiate.

• Home brew CO2 setup

Take the cfm requirement of the tool you want to use and divide it into the cylinder size in cubic feet.

Example: 15cfm tool and a 260cft cylinder
260/15= 17min

At that rate of flow your air tool will get pretty cool in your hands using nitrogen and expensive to use, about $60cyl refill, $150 cyl cost.

They make a 12v air pump, about $100, that you could use to fill a larger storage cylinder. Both for about $200.

You would also need to use a compressor run timer as those 12v compressors are only rated light duty. Look at compressors for air springs or air horns.

Nitrogen is alot safer than air. Nitrogen is not fuel to a flame.
