To calculate, sim-ply take the square footage of the space and multiply by the height of the ceiling to get cubicvolume. Then, divide by 60 and multiply by 0.35.Example: Total SQFT 1100Height of ceiling x 8Cubic volume 8800/ 60147x 0.35Airflow required (CFM) 51 cfm total* Always consult your local code for sizing requirements in your area.* If additional exhaust capacity is required, installation of a fantech bath kit in main bath areais recommended.***Illustrations &images in thismanual may not beexactly like unitpurchase, theseillustrations &images are forexamples only.***ASHRAE Standard 62.2 - 2004Sizing (Example) for minimum airflow normally required.Ventilation Air Requirements, cfm Ventilation Air requirements, L/s
