A new series of pressure - independent automatic balancing dampers (ABDs) from Ruskin - the ABD, ABD-SEA (with grille and steel enclosure box) and ABD-SEA-E (with grille and steel collar) - automatically regulate damper positioning for precise and automatic airflow in both supply and exhaust applications. The result is energy-saving performance that mitigates stack effect in high-rise buildings and improves comfort for building occupants. The dampers will be shown at booth C3334 during AHR Expo , Jan. 30–Feb. 1 at the Las Vegas Convention Center. Visitors can conduct simulations and demos on the dampers.

“Drawing on nearly 60 years of experience in the air control industry, we’ve developed a product that raises the bar in terms of making buildings more comfortable and healthy,” said Tim Vogel, director of air control solutions at Ruskin. “That’s because the Ruskin ABD is perfect for balancing supply ducts or more precisely controlling exhaust/supply ventilation requirements, improving indoor air quality and saving energy in the process, as it does not require electricity.”

The factory-assembled dampers also reduce installation, maintenance and labor costs by providing a single and simple, bi-directional design that works across the full pressure range in both exhaust and supply applications. Contractors and facility managers will find the dampers easy to install and manage, thanks to tool-free CFM adjustment - and up to 20 set point positions - with access through the damper grille, eliminating the need for the access door typically required with manual dampers. A universal Quick-Connect Adapter Ring further facilitates installation of the ABD, as it fits most adapter plates, and a Ruskiprene™ “T” seal ensures long-lasting durability.

The ABD also features a unique-to-the-industry, antimicrobial agent that mitigates the growth of mold and bacteria and contribute s to improved indoor air quality. As a result, the dampers lend themselves to restroom and healthcare applications, along with hospitality, commercial/retail, clean room and office building installations, and can be installed in horizontal or vertical applications.

The dampers are UL 2043 listed with a UL94V-0 flame and smoke spread rating. The ABDs are also qualified for use in all FAA, FHWA, FRA, AMTRAK and FTA projects. To download a brochure about these innovative new dampers, visit
