NOTES: * Includes 2-inch pleated filters. ** Power exhaust pressure drops are for sizing supply fan.
1. Return air opening pressure drop does not include an exhaust fan. Use the value in the powered exhaust air damper column to determine
return air pressure drop attributed to the exhaust fan assembly.
2. Front return is not available with barometric relief, exhaust fans, or return fans.
3.
Pressure drop for 12-inch rigid filter media includes a 2-inch prefilter.
