Car Air-con compressor pump?

[Mitchza89]

Hmm I had an idea. I was looking on Ebay for a compressor and I saw a car air conditioning compressor. Do these things run off A/C or does a drive belt run these things?

Does anyone know the pressure these things output?

isnt air condition systems a radiator to cool down the air?
if so i think it is a pump, not a compressor.
if it is a compressor i think it is powered by current. there are not so many belts in the engine room is it?


Edit: well here is pretty much all you need to know

Well it's a compressor as far as I know. I just read that the compressor is belt driven. The A/C power just engages/disengages the clutch on the pump. Hmmmm....

Would be great if you could just add a crank shaft or had it to an old mountain bike.

i don't think it is a good deal if you are going to pump over 30psi since a car engine runs at about 4000rpm.

mabe you can make an advanced compressor? a small electical engine and that stuff?

Yeah it's food for thought. I'll get a cheap compressor from the wreckers and see what I can come up with.

I got a mini compressor from True Value for $20. It goes up to 250 PSI. It plugs into a cigarette lighter outlet for a car. It's very convienient. But I wouldn't get it if flow rate is what your looking for. It pumps .7 CFM...

go for a fridge compressor theyre its whisper quiet and plugs into the wall

and the fridge compressor can take pressure from the inlet to pump faster.

nahh it hasn't been done yet... but in theory it could work

the fridge compressor is the best thing I ever built... really that stuff really helps a lot...

Well, I have seen air conditioning compressors on cars before (could have even been on this site). It is mainly an off-road type of thing, that way off-roaders can pump air into their tires after they let the air out when going through mud. The compressor that I saw went up to 125 PSI (I think) and there was a tank mounted under the vehicle to store the air.

yeah I suppose you can use belt driven compressors.. the only problems is that they are more difficult to use since you have to get a motor to operate them... this makes everything more expensive and noisey so all in all it would be easier to get a firdge compressor instead
