How to Identify an Older Air Compressor

Air compressors support various types of tools, which ultimately spared the strain of running off separate motors. With older compressors, the appeal may center on the rarity of an old machine, or even the novelty of having an outdated piece of machinery that is still operable.

Most air compressors should have a nameplate like the one in the image below. If it does, you should read it as it will have all the information you need!

If your compressor doesn’t have a nameplate, then you should search for distinguishable markings on the tank or the pump like brand names or model numbers.

Identifying an older air compressor can be done with the 4 following steps:

  • Check the backside of the tank to see if there’s a stamp that lists the year that the compressor was produced along with the manufacturer. If only the manufacturer name is present, do a google search of the brand compressors
  • Look along all sides of the air compressor for a patent number, which is often listed near the name of the manufacturer on most older compressors
  • Go to google patents and run a search on the patent number (if you find it), this will provide you with basic information on the model including the manufacturer and issue date
  • Upload images of the air compressor to a forum like this page where other compressor connoisseurs are likely to recognize the model
