A/C compressor to power air-bag Suspension?

[Revin68]

A friend who is an off-roader showed me a setup that is used to fill onboard airtanks that are used for airtools and flat tires. They basicly use an A/C compressor mounted traditionally on the engine that draws air off of the PCV valve (for lubrication i assume) and outputs air to a 5gal aux air tank. He had the clutch manually controlled by a toggle switch. (a pressure switch on the air tank would be my choice for compressor clutch control) anyone else ever seen this used before? I think it would be a great idea for an air-bag suspension. Any input?

I posted this on another website also and will share any feedback from there.

Thanks,
Robert
