    What size air compressor is needed to run a sandblaster? And what is the best material to clean rust off?

    I've got a husky 60 gallon compressor and a harbor freight blaster and they work great together with some cheapo play sand I bought at Lowes.
    Just make sure you have dry air lines.Any moisture whatsoever will make the blaster shoot nothing but wet air! Ask me how I know!:)

    I have got a Porter Cable 80gal model c7550..It does run alot when sandblasting but one thing to make sure is that you drain the tank after each day to prevent rusting from the inside.

    I also would recommend a inline dryer to keep as much moisture out of the lines as possible..

    I use a blast cabinet. I would say the smallest would be a 5hp running, not peak. I also have an 80 gallon unit. I would say that 16 and up cfm will do the job. Mine is an 18.1 and runs a lot. I will eventually catch up and cut off. The manual said it was designed for continuous duty and not to let it cycle more that 6 times an hour. As far as blast cabinets, you can size the nozzle to your cfm output.

    HUGE. You can't possibly have enough compressor for a sandblaster. 100 gallon 2 stage compressor, is not too much for a blaster. It will still run!

    5 HP 2 stage if you really want to do some blasting. My tank is 80 gal.

    Sand or black beauty for cleaning rust.

    Here's my answer to the question "how big of a compressor should I get for blasting?" The biggest you can possibly afford. I have an 80 gallon with a monster of a motor on it and I still give it breaks when Im blasting stuff. I've ran it so hard at one time that I turned all the copper piping running from the motor to the tank blue/purple from how hot the air was.

    Mine is a 2 stage 60 gallon, which keeps up but you still need to give it a break now and then

    my 5hp single stage is NOT big enuff. it runs like crazy and still have to let it catch up.

    btw if you use play sand wear a respirator, the dust from that shtuff is very deadly....or so ive been told.
