Table 4 Air Delivery - CFM (Without Filter) * **
* A fi lter is required for each return air inlet. This table shows the airfl ow
performance without a fi lter. To determine airfl ow performance with a fi lter, if a
3/4 inch (19 mm) washable media fi lter is used, assume an additional 0.1 in. WC
available external static pressure.
** The manufacturer default fan settings are based on model, refer to Table 24.
