At Aldes North America, we never stop innovating. As part of our commitment to providing world-class ventilation technology, we’re proud to announce the launch of the new CAR3®, a next generation constant airflow regulator.

A core product for Aldes North America for years, the constant airflow regulator has received a major update that incorporates industry-exclusive dual-side airflow adjustability and provides greater range of airflow for diverse applications. The regulators are calibrated to respond to pressure changes without need for an external signal or power source. It is available in a variety of assemblies to provide a complete solution.

Quality Construction

So, what’s not changing? Our customers can expect the same world-class function and performance —the same best-in-class durability, reliability, and design — from the CAR3® as always but with added precision and more options. Each unit is built in the United States and is constructed from a proprietary blend of amorphous thermoplastic resin.

Treated with antimicrobial, anti-static, and flame-retardant materials, the regulator offers high-end longevity and reliability. It requires no maintenance under normal conditions and is guaranteed for an industry-leading seven years.
