Here is the chart from the other thread if you missed it. Has the specs for the ren 14.
Does anyone know the years this class of compressors were produced? We just closed on a place with a garage and got the keys just before dark tonight. I have got to move a lot of junk to get up close to the compressor that powers the in ground single post Rotary lift with the H pattern lift with short arms that slide over the H shape base. From the deed the guy got the land in 1974 and built the garage before the house.
Over the weekend I will clear the compressor area (inside of shop so it is well protected) so I can get up to it. I know it is 220 volt and the motor is huge looking. It pumped up to 150 PSI before we turned it off one day before we closed and empty the lift went up fine and we had to use a ladder and get on it for it to come down. My tractor diesel mechanic was with me telling me how they work. He said the lift was not worn out because it has no rotation in either direction but it does have the safety pipe stand what you can pin at full height. The guy was using a heavy tie rod end.
The compressor turns very slow and makes a slow quacking sound so I hope that is normal. I do not think it is knocking or at least hoping so.
The seller's father passed 2 years ago at the age of 81 and said it has not lifted a car in 6-7 years but he used it as an adjustable height work table for making furniture until a major health failure in 2015. I guess it had not been used for a few years and it was still like 18" off of the floor. I found the oil fill plug for the lift in the floor near the cylinder and and going to check and see how much water is at the bottom
I can see he seldom purchased new but seemed resourceful in finding used equipment so I expect the Rotary lift and the Champion compressor much older than 45 years. The address that I could see today was Princeton Ill so it was before zip code time. I think the company name was just Champion Equip. There are numbers on the compressor behind the big cooling 2 belt pulley that I did not write down and those will be helpful.
In the meantime I am going to dig through 45 years of stuff and try get the shop back in working order the best I can. Two of the adjustable lift arms are mounted and two are laying over to the side because that was the first thing I checked out.
Thanks for all the posts about old compressors. I see some very old Champion compressors listed for high prices on eBay.
