VRAD : Negative Pressure Relief Door
VRAD : Negative Pressure Relief Door
The VRAD negative pressure relief door is factory set to open automatically at 2 in. wg (0.5 kPa) beyond normal system operating pressure, helping safeguard ductwork from excessive negative pressure conditions. If system dampers close while the fan continues to operate, the VRAD provides immediate pressure relief to help prevent duct implosion or structural damage. This automatic protection enhances overall system safety, reliability, and peace of mind.
