The Department of Defense, through the Defense Logistics Agency (DLA) Land Warren, is soliciting offers for a firm fixed-price contract to supply 43 circulating fans (NSN: 4140-01-464-9823, P/N: 12462717), with an option for an additional 43 units. This procurement is a sole source requirement directed to Rotron Incorporated, as the government lacks the necessary technical data for competitive re-procurement. The fans are critical for various military applications, and the selected contractor must adhere to strict packaging and delivery standards, including compliance with MIL-STD-2073-1 and MIL-STD-129. Offers are due by December 22, 2025, and interested parties should contact Rosanna Madigan at Rosanna.madigan@dla.mil or 586-208-0688 for further details.
