Notes:
1. Static pressure drops of accessory components must be added to external static pressure to enter fan selection tables.
2. Gas heat section maximum temperature rise of 60 F.
3. Throwaway filter option limited to 300 ft/min face velocity.
4. Bag filter option limited to 740 ft/min face velocity.
5. Horizontal roof curbs assume 0.50” static pressure drop or double the standard roof curb pressure drop, whichever is greater.
6. No additional pressure loss for model SXHF.
7. 90-130 ton roofcurbs adds no pressure drop.
