A register booster fan, also known as a duct booster fan, is a mechanical device used to increase the airflow and pressure within a ventilation system. It is typically installed in ductwork to provide additional air movement and overcome resistance caused by long duct runs, filters, and other system components.
Register booster fans play a crucial role in maintaining optimal indoor air quality, especially in large buildings or areas with complex ductwork. They help to ensure that conditioned air reaches all parts of the building, preventing stagnant air and potential moisture buildup. Additionally, booster fans can improve energy efficiency by reducing the load on the central HVAC system and optimizing airflow distribution.
