    First of all, I did do a search but couldn't find the answer.

    Need some advice - I have decided to add an air compressor to my garage to power the following tools: impact wrench (one powerful enough to get ANY mower blade off without a problem), tire filler, compressed air gun to keep things clean.

    My question is: How many hp and gallon compressor would you guys recommend. I've got my eye on a 3.5hp, 25 gal Craftsman Professional portable air compressor. Will this do what I need it to do? I don't like sissy stuff cause I don't like to have to do things again because I didn't do it right the first time (includes purchases), especially from being under-equipped for the job.

    Also, are there other things a compressor would be useful for (excluding painting because I don't know how to paint)?

    I have a Speedy Air 5HP 30 gallon, and it seems to do fine in all aspects. I would recommend the same at least, if not bigger. I have a buddy who has a 60 gallon 15HP(i think) and it is very nice, probably what I will get if/when this one goes south on me.

    Don't need much. I use a 2HP with a 4 gallon tank. It allows me to carry it on the trailer. If need air just plug it in a cleints front porch outlet fill the tank and have air quick. It powers my impact wrench and all tools with no problem. Keep it small.

    you need about 5cfm@90psi to run an impact wrench on all types of applications.. the other two uses can be done with much less air pressure..

    I too have a 2hp 4 gal. that I load in the truck every day. Love how portable it is, and have no problem running all the air tools. I love my neighbors compressor (60 gal. w/ 18 or 20 hp motor), and use it every time I can. If you can afford it, get one of each.

    I got a 25gallon 5.5 hp Porter Cable. I think it cost under $300.00 . I can run just about any air tool with it, that should be plenty for you. I've used a 1/2 impact, air ratchet, grease gun, die grinder, air sander air chisel.

    I'm looking for one as well but I want it to be able to manage a Dual Action sander. All the charts I see at Lowes and elsewhere claim that the 5HP won't handle a sander! Someone let me know if they will, I need to sand and repaint my trailer this fall.
