The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking a sole source procurement for a circulating fan, identified by NSN 7R-4140-016986248-H5, with a quantity of one unit required for delivery FOB origin. This acquisition is critical as the government lacks sufficient data to contract with any source other than the current supplier, emphasizing the importance of Government Source Approval prior to award. The item is subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement, highlighting its international procurement implications. Interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which can be accessed online, and should direct any inquiries to Casey M. Brown at casey.m.brown20.civ@us.navy.mil.
