a. For 800 CFM-16-in. (406 ram) round or 14 1/2 x 12-in. (368 x 305 ram) rectangle.
b. For 1200 CFM-20-in. (508 ram) round or 14 1/2 x 19 1/2-in. (368 x 495 ram) rectangle.
c. For 1600 CFM-22-in. (559 ram) round or 14 1/2 x 22 1/16-in. (368 x 560mm) rectangle.
d. For airflow requirements above 1800 CFM, see Air Delivery table in Product Data literature for specific use of single side inlets. The use of both side inlets, a
combination of 1 side and the bottom, or the bottom only will ensure adequate return air openings for airflow requirements above 1800 CFM.
