Pressurizing Cornie keg with compressed air

[Gizzygone]

I bought a 1.75 gallon cornie keg to use to clean my beer lines (instead of a hand sprayer).

Any reason not to use compressed air from my compressor to pressurize the keg? Or should I stop being cheap and just use the CO2?

Why not, I do all the time.
Check the max PSI stamped on the keg, don't just hit them up with 120psi like you would your tools.

I do it. Your fine.

If the compressor is an oil bath type (larger and not potable) then this would not be a great idea.

I didn't think about this... Use an oil-less compressor and remove the tool oiler if you have one.
I use my little oil-less pancake compressor in my brewery and my bigger oil cooled one in my shop.

Eh: guess I’ll stick with the CO2 type.

Mine is a larger compressor, and while it doesn’t have an Oiler, I’m sure there’s enough oil blow-by to be of concern.

i guess I could grab one of those portable air tanks and fill it with my bicycle pump, but I can’t imagine it uses too much CO2 to purge the lines.

You can also use a hand pump or rig up a bicycle pump to do the same thing.

When I drain my pancake compressor what comes out immediately ends any thought of using it in my brewery...

Cheers!

A hand pump with a ball-lock QD works well for me to clean/sanitize a three-tap kegerator. Not hard to rig up your own, but there are commercial ones too.

Another vote for not a chance. I cant even drain my compressor on a homeowners driveway from the milky oily nasty water that comes out.
