• Ideal for maintaining di erential room pressure, when doors are opened between clean rooms & external atmosphere
• Remains closed at pressure below the set pressure & open fully at pressure only fractionally above the threshold
• Cut-out Dimension: 325 (H) X 300 (W) X 100 (D) We can customized the size as per user requirement.

Pressure Relief Damper is a critical component in HVAC (Heating, Ventilation, and Air Conditioning) systems, designed to maintain and control air pressure within a confined space. It is primarily used in environments where maintaining a consistent pressure level is crucial, such as cleanrooms, laboratories, data centers, and hospital operating rooms.

The Pressure Relief Damper operates by automatically opening or closing in response to pressure changes within the space. When the pressure exceeds a pre-set level, the damper opens, allowing excess air to escape and thereby preventing over-pressurization. Conversely, if the pressure drops, the damper closes to maintain the desired pressure level. This dynamic operation ensures that the internal environment remains stable and safe, protecting sensitive equipment and processes from pressure-related damage.
