What the agency is buying and why it matters
The Naval Surface Warfare Center Carderock Division is seeking information from industry to replace obsolete parts in the IM-272A/WDQ Air Particle Detector (APD). This effort involves designing and producing prototypes for several key components, including the Power Supply Motor Controller, AC/DC Converter, Display Assembly, Paperfeed Assembly, Flowmeter Assembly, and Door Hinge.
Vendors would be responsible for providing two prototypes of each replacement part and conducting performance testing to ensure compatibility with existing APD units. This is an opportunity for businesses with expertise in electronic component design, manufacturing, and testing, particularly those familiar with defense equipment standards.
