Definition of Pressure Relief Damper

Pressure relief dampers are specialized devices that control the airflow within a duct system.

These dampers are designed to maintain a constant pressure by adjusting to various airflows. When there’s a decrease in differential pressure, the damper closes, serving as a safety or controlling mechanism.

The functionality of pressure relief dampers is far-reaching, and their precision is instrumental in preventing unexpected overpressure or negative pressure downstream in the system.

Importance in the Ventilation System

In both commercial and residential buildings, pressure relief dampers play a vital role in managing air pressure within the ventilation system.

They ensure that the air pressure within the ducts remains constant, preventing potential damage and inefficiencies that could arise from pressure fluctuations.

The utilization of pressure relief dampers significantly contributes to the overall functionality and reliability of HVAC systems, leading to optimized energy consumption and enhanced comfort for occupants.
