The CD50CE is Air Movement and Control Association Intl. Inc. (AMCA)-licensed as Class 1A and, due to low-leak extruded aluminum, meets the International Energy Conservation Code (IECC).
The Model HBT-221 is a commercial-grade, rectangular, bubble-tight damper with square blades. It features a blade seal mechanically fastened to the blade that is field-replaceable; a flanged damper frame for easy mounting; and is available with a full range of electric, pneumatic, or manual actuator options.
As architects and engineers draw up plans for commercial buildings, it is a common practice to design openings in walls. In many cases, these openings allow for intake and/or exhaust air that supports the building’s HVAC system and are fire-resistive rated.
The Model SMD-401EF smoke damper features an extruded aluminum frame and airfoil blades. It is available in sizes up to 192 inches wide by 120 inches high with a wide range of actuators in modulating or two-position operation.
The Model ABD-SEA-E provides precise and automatic airflow regulation for supply or exhaust ventilation systems in any residential or commercial building. It is designed for use in any HVAC application with a static pressure between 0.2 and 2.0 inches water column.
This series of pressure-independent automatic balancing dampers regulate damper positioning and provide precise and automatic airflow in both supply and exhaust applications, which results in energy-saving performance that mitigates stack effect in high-rise buildings and improves comfort for building occupants.
Ruskin automatic balancing dampers (ABDs) regulate damper positioning for precise and constant airflow volume in both supply and exhaust HVAC applications.
