Back in 1957, two men from Johnstown, PA began building small air compressors for the construction industry. Known for their dependability, these machines became the most popular portable compressors on the market. Everyone in the industry knew that the little blue compressor from Johnstown was as reliable as the men (and the Western Pennsylvania work ethic) that built them. Fast forward 50 years and you’ll still find dependable blue compressors made at the J-Air factory in Johnstown. Though many things have changed since 1957, one thing remains the same… Blue is Best. Period.
