Portable Compressed Air

Here is a easy way to have compressed air whenever and wherever you need it. First you will need an air compressor capable of pumping up to 3000 psi(207 bar).

I use an old MAKO compressor.
Next you will need one or more SCUBA tanks. I have eight.

Then you will need a yoke and regulator.Attachment 41001
I only fill mine to 2500psi.Attachment 40999
They will last a surprisingly long time and you will always have air when you need it...

Also have made a DIY compressor rig for SCUBA diving.
I used a WW2 3000 PSI compressor modified to use a belt driven 110 VAC motor.
For filtering we used a proper pressure vessel and tampons to trap any oils and impurities.
To be on safer side we used vegetable oils.
