I think you'll be hard pushed to find a good compressor at that price. For what I've seen they tend to start at £80 and move up.
If I were you, I'd ask at UKSGC, a few of they guys there have compressors, or get an air tank.
I would be inclined to make a backpack mounted air tank. Have a high volume, and run it around 16 bar, then you can run your gun around 7 bar (regulated), you should get plenty of air at a good pressure

Uber cheap random cheap skate ghetto option

Not sure, that's a bit of a low budget. Check out your local secondhand magazine (the quokka over here) or discount auto/hardware store. Not that I've ever been in a walmart, but you could try there.

I tested my fridge and interestingly enough, it peaked at 1243 watts and stayed constant at around 1100. I thought it would peak higher.

1100 Watts is too much.. Watch the frost free defrost cycle. They run a heater to flash defrost the freezer coil. Your reading is right for the defrost cycle. Please check again. Most fridges run at under 500 Watts.

Yeah, you're right. However, I left the meter hooked up and was walking by and it said 300 watts. I could hear the compressor running, but then it started gradually stepping down until it settled at 200 watts. Then when I opened the door it spiked to 350 watts, and as soon as a closed it, it went back down to 200 watts.

Is this thing some kind of variable speed compressor, or is it just possessed? :lol:



And for fun, I tested my portable air conditioner, and it stayed constant at 950 watts.

Um,, Brings up the question.. Does the light stay on when you close the door?

As I mentioned earlier on AC compressors, They are bigger all the way around. More power baby :!:

@tech
how much are used AC compressors??

if it's price was low enough it would make sense but AC isn't as popular in europe as it is in the states so, at least for me, getting a fridge compressor is a piece of cake and they are really chea

on the other hand AC compressors are almost impossible to find

it would make sense to compare flow of an average firdge ocmpressor with that of an AC compressor... and then compare whether the increase in flow is really worth the price

For me.. Free.. junkyard oldie tossed junk. Some still have working compressors.. Pick up a couple. Some just lost the gas and the compressor is OK. Some have failed start caps or relays. Need to learn to identify those. The starter off one with a failed compressor of the same size may have interchangeable starter relays.


When done, the carcass is a great test target. :D

Could you test a fridge compressor alone (without fridge)?
Under 500 watts is not that much...
