Just been browsing Ebay and came across this, Fridge compressors for $9.99 american. Maybe a good alternative if you cant find an old fridge laying around etc

God that's cheap. Oh, if only....
Thanks for the heads up mate. Good luck in finding one!
You can usually find old compressors pretty easily. A lot of refuge tips and rubbish tips hold old fridges after they've been thrown out due to their gas running out.
We have a couple of old fridges but my parents won't let me muck around with anything that uses 240V. Fair enough reason I guess.
....But only if they knew I was messing around with 400-500psi with the pumps I make
Oh ignorance is bliss!

Warning.. Read the specs.. 3 phase power.. This is a commercial unit. It won't run on home single phase power.

You live next door to a sparky? Fantastic!
I can go one better. My step dad is a lisenced gas fitter

I can't win though. He was a fitter and turner in the army for 20 years and so he hates what I do purely because he knows the potential of the power and the damage it can do in the wrong hands.
I mainly love making spuddie's because I love the mechanical side of things. I love more or less turning a pile of scrap and corroded plumbing parts into a beautifully polished peice of working machinery.
Don't mind my rant, had a few brews...

3 Phase means you will need 3 phase wiring, whereas most housing will have single phase. Beware of that before buying.

For those who don't know. US home power is single phase. 120/240. It is one hot and 1 neutral. The second hot in 240 is 180 degrees out of phase. (opposite polarity of the same phase)
In commercial power using 3 phase, there are 3 hots to ground. Each at 120 volts. (sometimes 480 volt for big stuff). Each phase is 120 degrees from each other, not just a polarity reversal of 180 degrees. Instead of 240 between hots, it is 208 volt.
3 phase power is 3 hot legs, each 120 volts to neutral and 208 volts between each leg. For motors this eliminates all need for start and run caps as a rotating magnetic field is created with the 3 phases. Efficiency and reliability is higher with fewer failure prone parts.
Sometimes shop tools come with 3 phase motors. To run them in a home shop, a rotary phase converter is used which is a single phase motor and 3 phase motor all wired into the same motor. 1 phase in and 3 phase out. They are big, noisy, and expensive.

This page has prices..
You don't want to buy one to run a $10 fridge compressor.
