Brunner Air Compressors

As I'm writing this page about Brunner air compressors, I can't help but wonder what the Brunner Air Compressor Corp., established in 1963 in New York State, and gone bankrupt in May 1966, has to do with the Brunner air compressors that have been in use in North America since when, the late 1910's or thereabouts?

Probably little. I could not find a connection.

Questions about Brunner air compressors still ricochet around the internet however with some landing on You may find some answers on this page.

In my research about this brand, I discovered a photo of this beauty, a restored 1951 Brunner.
