Quiet air compressor
I have a compressor which is almost good enough for the media blasting that I need to do, but the thing is CRAZY loud.
Has anyone found an air compressor they are happy with? Without going completly over board? I plan on hooking up a blasting cabinet and blasting all the suspension parts.
Thanks

My Sears dual stage works well and the ingersol rand that my father has works even better. Just like HP how much do you want to spend and how fast do you want to go. Or in this case how much CFM do you want to move and how much do you want to spend? My compressor was about $750 and does well to keep up with my blasting cabinet while the IR is about $2k and never misses a step.. Just depends on you cash flow..

Noise and air compressors go hand and hand some are louder than others that's why shops have compressor rooms. Anyway with any kind of blasting equipment the most important things that you need are enough CFM'S and air volume storage. I have an 80 gallon air compressor with 23.5 CFM'S and I use another 60 gallon storage tank . Blasting equipment are air hogs and will deplete your air storage.If I were you I would first blast your suspension parts with a course media that way you get the nasty off and then go over them in a blast cabinet to finish blast them and be ready to prime and paint.That is how I do my nasty parts. You will also keep your cabinet media clean and not have to deal with all the crap.

As a general rule of thumb, expensive compressors are quieter and cheaper compressors are louder. It is simple economics, and it is pretty hard to make a cheap, quiet compressor. I had a 5hp 2 stage Sanborn for years, and while it worked well, it was incredibly noisy. I replaced it with a Curtis Toledo of the same capacity, it is is way quieter.
The key is compressor RPM. You can get more capacity out of a compressor, you just have to spin it faster. A lot of cheap compressors use the exact same compressor head from about 3 HP all the way to 7.5 HP. Obviously, the only thing they do differently is how fast they spin the head unit. A quality compressor will turn at way slower speed, will last almost forever, and will be way quieter. Also, most of these compressors are solid cast iron as opposed to being aluminum. My Sanborn finally just threw a rod. My Curtis just loafs along at half of the speed of my old compressor.

Screw Type Compressor
If you have about $5500 burning a hole in your pocket you could buy a rotary screw type compressor. These things are very quiet, but they are not cheap!
