ZooFans-122214-body.jpgThe IC20 Drop-In fan from Zoo Fans is designed specifically for drop ceiling (T-bar) spaces with ceiling heights from 8 ft to 20 ft. The patent-pending diffuser has an integrated jet ball exhaust that is easy to adjust to direct the airflow. Variable speed controls make it simple to dial-in comfort — one-to-one, in zones, manually, or automatically. This fan system also includes a low-profile isolation plenum so it will not compromise above-ceiling air or HVAC return plenums. The entire unit easily replaces a 2-ft by 2-ft ceiling tile and installs with less than 18 in clearance top-to-bottom.
