The Department of Defense, specifically the Department of the Air Force, is issuing a sole source procurement notice for maintenance services on the CASS Compressor machine, with Kaeser Compressor, Inc. designated as the sole provider. The requirement arises from the necessity for specialized maintenance and parts that can only be supplied by Kaeser, the manufacturer of the machine, as no alternative vendors can provide the necessary filters and components. This procurement is critical to ensure the operational efficiency of the CASS Compressor, which plays a vital role in the Air Force's operations. The estimated project cost is $34,160.74, and interested parties can contact Heather Long at heather.long.10.ctr@us.af.mil or by phone at 580-213-7179 for further details.
