Yes you can ! You will need a presure switch (viair do one for less than £20) and a small tank, one of them small disposable welding gas bottles works great and plenty big enough for a couple of arb's
Just unscrew the valve out the end and put in a fitting, it's 1/8 bsp.
Or if you want to be really cheep you can use a coke bottle (yes really ! It's been proven they take the pressure and if they do get damaged then it doesn't chuck shrapnel at you)
There you go a couple of good ideas for a tank and mostly free.
I wouldn't go with the coke bottle though!
I don't know what fitting the fridge reciever would have , I expect it would be a soldered pipe but it will be rated at the pressure needed as would the welding gas bottle.
