We bought this compressor about 8 months ago and it had 4 hours on it. We have since put 16 more hours on it for a total of 20. It is in excellent condition. We bought it as a temporary solution to our big compressor being down. It is now fixed and we currently have no need for the Bauer. It is located in Panama City, FL and still currently hooked to our fill station so you can see it run if so desired. It currently has the single phase electric motor on it and also comes with the gasoline motor. I believe the compressor is 3.9 CFM and can fill to 5000psi (that would probably take awhile) however we have used it to fill AL80s to 3000psi. It is not recommend to run o2 through it and we haven't but some say that they have used these compressors for nitrox. If you need any in particular specs please pm me. I am in PC at least once a month so I can pick it up and arrange to meet someone in West Central GA. Someone is available at the shop any day of the week besides Sunday if your in the PC area. $2300.00 Thanks!
