Considering in making a quiet air compressor from a refrigeration or air conditioning unit compressor motor. Lots of info out there in You Tube and know they can attain high pressure. But need to know what size to look for in order to attain at least 2 CFM for spray finishing.
Is there any info out there that can relate to CFM abilities of such units?
Thanks, Daddydave

No idea, but have you tried inquiring in the
comments section on these YouTube videos?

Have you look at the California Air Tools compressors? Mine is somewhere around 58db, which is quieter than my dishwasher.

+1 on California Air. I ditched my noisy HF last winter for one and the difference is unbelievable. You can hold a conversation right beside it while it’s running.

I see several problems trying to re-purpose a refrigeration compressor. One big problem is that most require oil mixed in with the freon to lubricate them. You could run oil through with the air, which might be suitable for pneumatic air tools that require lubrication also, but would not work at all for spraying finishes. There are a few that use an external oil supply, but it might be cost prohibitive to find a suitable one. Then you also have to figure in the costs of the air storage tank, plumbing, pressure cut off switch, wiring and then figuring out how to mount it all in a single package. Would probably be a lot less hassle and cost to just buy a quiet compressor like the CA ones mentioned above. Keep an eye out on CL, as they do show up from time to time.

Cheers,

I too have the California Air compressor and love it. I don’t believe a compressor from a refrigerator puts out enough CFM to be an effective air compressor.

Sorry that I can’t give you any useful information to your inquiry, but if you want a quiet compressor with good features, try one from CAT. I have the California Air Tools twin cylinder, 2 hp., twin stack compressor and love it. It is quiet, cycles quickly and they are backed by GREAT customer service. I had a minor problem with mine last winter, sent them an email and got a return email in 20 minutes solving the problem. You won’t regret getting one, as they are reasonably priced too. Good Luck, Have Fun and Work Safely!
