For more than 100 years, US Air Compressors have been the work horse powering service station equipment,
plant floor operations, and countless other applications. Today, the US Air Compressor line of products is
owned by Collins Equipment Corp. We are proud to continue that tradition of excellence by supporting two
of the most reliable compressors ever built:
