Pressure Independent Variable Air Volume (VAV) Damper

Optimize HVAC performance and energy efficiency with this Pressure Independent Variable Air Volume (VAV) Damper. Designed for modern commercial and industrial buildings, this unit ensures that the airflow delivered to occupied spaces remains consistent, even when there are significant fluctuations in the supply duct static pressure. This independence from duct pressure variations eliminates the need for complex pressure-compensating controls, resulting in a more stable and responsive ventilation system.

The damper is engineered with adjustable double deflection blades, which provide superior flow control and reduced aerodynamic noise compared to single deflection designs. This geometry allows for precise modulation across the entire operating range, from a minimum of 100 CFM up to a maximum of 3100 CFM. Integrated with a standard airflow probe and a robust actuator, the VAV damper continuously monitors actual airflow and adjusts the blade position in real-time based on signals from the room thermostat or building management system (BMS).

Key Features & Benefits

• Pressure Independence: Delivers consistent CFM regardless of upstream pressure changes, ensuring reliable comfort and air quality.
• Wide Operating Range: Suitable for various terminal sizes, handling airflow volumes from 100 to 3100 CFM.
• Double Deflection Blades: Enhances flow stability and minimizes turbulence and noise within the ductwork.
• Integrated Sensing: Comes equipped with an airflow probe for accurate feedback and precise actuator control.
• Energy Efficiency: Reduces fan energy consumption by modulating airflow only as needed, rather than using constant volume methods.

Applications

Ideal for use in office buildings, hospitals, schools, and retail spaces where individual zone control is required. Compatible with standard HVAC ductwork and integrates seamlessly with major BMS protocols.
