Thread: Air Compressor Wanted

Posted here as it will be used for cars and motorcycles.

I will use for minor spraying jobs but its main use will be for torque settings and general blow cleaning. Had a quick look in HomePro at Pume, which I've never heard of. There were one or two others called JET, and another I can't recall. I'm figuring 2hp should be more than enough for my purpose.

Puma costs about 6k for 2-2.5 hp and the others were a couple of K cheaper.

Anyone use one and have experience on the ones sold at homepro.

Cheers.

Barty has a shop but I don't remember if he has a compressor? His rattle gun is electric. Not cheap but...

Also I believe the rattle guns use almost as much air as a spray gun. Do you already have the air impact wrench?

Duty cycle is the most important factor for your choice. If you are only using the rattle gun sporadically. If your impact wrench is 3/8 research says you'll need 7 CFM if you use it for 21 seconds. 3 CFM if you use it for 9 seconds. The tool will have the air requirement written on it or in the manual. 1/2 in uses 11 CFM if used for 21 seconds.

If you are going to take a wheel off a car then say 5 nuts at 2 second per nut is 10 seconds so 3 CFM? Then put it back on another 3 CFM how long between that? If you are doing two wheels...

This from a compressor site

Get a tank large enough to supply the air for that 30 seconds, and make sure the compressor can fill it up in less than an hour (with all of the other things running,) and you should be okay.

If you are only taking off one wheel every day it probably won't matter or just for home use as you can have a coffee or a beer while the tank refills. Never use impact wrench to tighten wheel nuts. Use the tool supplied with the car. I know everyone does but it makes them extremely difficult to get off if one has a puncture.
