Model CAR-T

Constant Airflow Regulator

Model CAR-T constant airflow regulator with transition is designed to save a significant amount of money and energy by precisely controlling airflow to balance HVAC systems without the need for electrical or pneumatic controls and sensors. A self-regulating aero-wing and spring piston design automatically adjust for variable duct pressures caused by building duct design, thermal stack effect, dust build up in air filters, and other varying building conditions. The CAR-T constant airflow regulator works best to help control the volume of make-up or exhaust air in high rise applications with the added benefit of having a factory supplied square to round or rectangular to round transition, allowing an easy connection to standard ductwork.
