I'm almost certain this would require a compressor swap. I doubt the stock A/C compressor outputs enough PSI to fill a reserve tank or provide "portable air".

However, based on the design of the compressor, you could modify the lines coming off the back of the junction block on the back of it. This block provides access to both sides of pressure.

The compressor of choice is an older York. Search online and you'll find lots of information on this. It's been discussed on here before also.

Based on the amount of time it took to discharge and the power behind the release of pressure when I disconnected my A/C system, I would say it maintains a steady pressure of 80psi or so. This would pump a tank up just fine. However, I'm anxious to see what someone with real data has to say...

Sounds like a great idea, whether it's for on board air or for horns : )

The FS-10 A/C compressor has the following characteristics:

l A ten-cylinder swashplate design utilizing the tangential design mount.

l Displacement of 170 cc (10.4 cubic inch)


Im not sure how displacement and rpm effect air volume output.


You will need a air tool oiler on the inlet and a oil separator on the outlet.

i think it would be better to just run the electric one.

pull the compressor and get the belt for a 4.0 that doesnt have A/C

The reason why people use the York for onboard air is because certain models had integral oil reservoirs. This type of compressor was found mostly in the A/C systems of 60s and 70s cars.

Modern A/C compressors, including the Ranger's, use lubricant carried in the refrigerant. If you try to use the stock Ranger compressor for onboard air, it won't be long before it fails from lack of lubrication.

From what I've heard, it may be possible to rig up an oiler of some sort that would allow the stock compressor to survive. That means extra work. On the other hand installing a York would require fabbing brackets and making the pulleys compatible.

What about your A/C system is inoperable, other than the lack of charge? A recharge is quick and easy!
