The innovative CAR3 constant airflow regulator by Aldes was awarded winner for its innovation in the Ventilation category. It features a state-of-the-art design with industry exclusive dual-side airflow adjustability and greater airflow ranges for a variety of applications. The patent pending airflow technology allows you to set or change the airflow quickly, in supply or exhaust applications, without removing the CAR3 from the duct.

The technology is capable of maintaining constant airflow within +/-10% of the scheduled flow rates, within the operating range of 0.12 to 1.2 in. w.g. differential pressure for low-pressure models (CAR3-L), or 0.4 to 2.8 in. w.g. with high-pressure models (CAR3-H). CAR3 solely operates on duct pressure and requires no external power supply or sensors, and will be rated for use in air temperatures ranging from -25°F to 140°F (-32°C to 60°C). CAR3 must be equipped with a double lip gasket to provide a secure, leak free installation into rigid round duct, take-offs, collars, etc.

Each regulator features a dual-side adjustment dial to allow for changes in airflow set-point while installed in either the supply or exhaust direction without removing the regulator from the duct. Regulator is classified per UL 2043 and carries the UL mark indicating compliance. The constant airflow regulator is enhanced with antimicrobial, anti-static, and flame retardant additives for increased durability and safety, and covered under warranty for a period of no less than seven years.
