When buying used rotary air compressors, always look at the number of hours on the compressor. Generally, rotary screw air compressors require a major overhaul around 50-70,000 hours on the airend, which includes replacing the bearings and realigning the rotors. A normal airend rebuild can be around $2,500 to $10,000, all depending on the brand and size (don’t forget you’ll also need to replace the lubricant and filters in a rebuild).
When buying a used air compressor, see if the seller completed a preventative maintenance on it, this includes changing the oil and related filters. If not, this could be a $1,000 adder.
Their is a reason people trade in compressors. The majority of the time, they had issues and were tired of investing additional capital in repairs. Be careful and don’t buy someones problem.
Given, you want to consider the age of the air compressor and hours, we generally see $125 to $200 per horsepower. Therefore, you should pay $3,125 to $5,000 for a used 25 horsepower rotary screw compressor.

* Remember, their are some compressor brands that you could buy new at some of these “great” prices. Do your research!
These are only a few tips to help you when considering a used compressor for your shop.
Don’t forget, you also have leasing to own as a option… :) (We will have more on leasing air compressors in future blogs).
