ADT-LBG7750 Linear Bar Grilles are designed for installation in the side wall, sill, floor and ceiling, and are recommended for supplying heated, ventilated or cooled air and for returning or exhausting room air.

Their performance assures confident use of cooling temperature differentials up to 25°F at predicted low air motion (35fpm) in the zone of occupancy. ADT-LBG7750 Linear Bar Grilles perform efficiency with air loadings of 1 to 2-1/2 cfm per square foot of floor area or 6 to 15 air changes per hour (based on 10ft. ceiling height) and sound level range of NC 25 to 35.
