out of things. I get them refilled at the local dry
ice/CO2 dealer. I purchased a high flow regulator at
the HVAC supply house and use the CO2 to run air tools,
inflate tires and clear clogged pipes and coils.

Why run your tools on CO2? What is the advantage over just
filling from your compressor, or the local gas station?

The 20lb cylinder is filled with liquid CO2 which flashes
into gas when the pressure is let off of it. It boils at
-70 deg F and the 20lbs of liquid CO2 will produce a lot
of gas. Think of it this way, your car runs on the fumes
or vapor of gasoline so why not have a tank of vapor? It
wouldn't last very long would it? One pound of liquid CO2
will produce 8.741 cubic feet of gas.
