i have a 33 with an oil-less system and it is loud. i like it. i didnt have a 220volt so i was kind of at a cross roads. i would have had to have one installed because i dont even have one in my house. my stove is gas and my house nothing runs off more then 120. i like my compressor tho it works well and gives me no problems. i got use to the compressor kicking on so it dont bother me
