I've just burnt out my electric impact wrench, and my previous cheapo electric one destroyed its gearbox before that, so fancy trying an air one.
Will my existing compressor be capable of running one?
I have one of these 24 litre Sealey ones:

You will need a bigger compressor at least 100 ltr tank and 13 cfm compressor to use a decent air wrench
I have a compressor similar to that Sealey one, I get maybe one or two thumps out of an air gun before it has to recharge. I bought myself a Clarke mains powered one and it seems to do a much better job.

Depending on if its for undoing difficult tight stuff or for undoing everything I would say that hose size is far more important than compressor size. And yes a small compressor will quickly run out of air using a decent rattle gun.
What are you hoping to get?
I use a 2hp 25l and it's ok. But I work in bursts and accept it needs to run to recharge.
what impact gun you got, i have one here with 2 dead 24 volt batteries gathering dust
My current one is 230v and claims 480lbft. I'm stuck on a mondeo crank bolt that's loosened 3 turns then hit stuck on its thrrsdlock. They
have a reputation for being tight.
I think maybe I need to use some heat too, or more of an in/out technique.
I've left it with a slosh of plus gas to see if that helps.
heat destroys threadlock so give that a bash

Excellent - cheers chaps. I have a proper plumbers Rothenburg so I'll but a new 240v one for now and give that a shot.
I stripped down the dead one yesterday - motor windings melted from over-work. It was one of these - sold under various brands:

I picked up a bare 18v Dewalt impact gun at Stoneliegh for £140 , seems to have as much torque as my SnapOn air gun , well impressed for the price.
I've used a hot air gun previously to help remove the crank pulley bolt on C20XE engines and they are renown for being difficult to shift

The blowtorch and a new gun shifted it :-)
