Had to buy this today. These were £90 then £70 now £35. 3 yr warranty. Happy days. Not sure if this was national but there was about 5 left in the barrow store.

Anyone voting cold please let me know where you will get one cheaper than this?

You can't get one cheaper than this but its a wild goose chase to find one, unless like you you're close to Barrow Aldi as you have established they had stock when you visited.

I got one for £34.99. The price said £69.99 but scanned at £34.99. I also got one of their impact wrenches and it wouldn't take off wheel nuts torqued upto 110 nm.

Even more expensive electric impact wrenches are rubbish at doing over-torqued wheel nuts. I got a Clarke one that is rated for 450Nm and that wouldn't shift my wheel nuts. Had to use a breaker bar and my entire body weight bouncing up and down to remove it.

Been after one for ages but still 79 at my local. So annoying

Ask if they'll price match the barrow store :laughing:

Any decent 1/2" air impact gun is going to use at least 15cfm of air at 8bar pressure (ignore the 7ish bar air consumption figure at 50% duty cycle; this just means you need a compressor that gives you at least 14cfm free air delivery). The compressors generally delivery about 3cfm free air per 1hp. Often the compressors are specified as either piston displacement or intake air figures (complete bollucks). Even when a free air figure is given it is usually at atmospheric pressure (as the pressure builds in the tank the air flow delivered drops).
If you want to know what the air flow for your compressor then first check that there are no air leaks (a little soapy wateraround the cylinder head and delivery pipe unions whilst running and around any other unions when full. Then using a stop watch from empty time how long it takes to fill the tank until cut off (now convert the time into a decimal of the minutes eg. 3 mins and 30 secs = 3.5).
Now take the tank size in litres and times that by the cut off pressure in bar.
Now divide that figure by the first figure (3.5) and then again by 28.3....there's your free air delivery over a tank fill!
So this compressor may be.....
50×8=400
400÷3.5=114.3
114.3÷28.3= 4cfm free air delivery.

Will it blow hard enough so I can use a spray gun to powder coat motorcycle panels?

compressor would not even need to be running to shift a wheel nut
If up to pressure, it should shift a wheel nut in about 1/4 of a second. Free air delivery of the pump does not make any difference. You should be able to get all the wheel nuts off before the compressor even cut in again.
Any flow limitations such as small bore pipes will limit the amount of torque from an impact wrench.
For running a spray gun continuously then that is a different thing altogether. Your arguments are correct in that case.
