A series of pressure-independent automatic balancing dampers (ABDs) from Ruskin, ABD, ABD-SEA (with grille and steel enclosure box) and ABD-SEA-E (with grille and steel collar), automatically regulate damper positioning for 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 factory-assembled dampers also reduce installation, maintenance and labor costs by providing a single 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 Quick-Connect Adapter Ring further facilitates installation of the ABD, as it fits most adapter plates, and a Ruskiprene “T” seal ensures durability.
The ABD also features an antimicrobial agent that mitigates the growth of mold and bacteria and contributes 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.
