The Cases for and against Manual Volume Dampers

Army Corps of Engineers construction documents for a military hospital in Fort Bragg, N.C., show more than 2,000 manual volume dampers (MVDs) upstream of variable air volume boxes. However, the installation of these dampers became the subject of a dispute during construction. According to the subcontractor, the system was a high-pressure system, making MVDs detrimental to its operation.
