Dayton 450Z11 Inline Centrifugal Duct Fan
This Dayton 450Z11 inline centrifugal duct fan moves air through 8 in ducting in residential and light-commercial ventilation systems. Its steel housing measures 13 in diameter by 10 in length and contains a single-speed motor rated for 120 V and 1.5 A. The unit delivers 571 CFM at zero static pressure and 521 CFM at 0.100 in. SP.
Installers needing a straight-through duct booster
This fan suits installers who need a direct-drive booster that fits inside an 8 in duct run and operates on a standard 120 V circuit. It is not for systems that require variable speed control, higher static pressure beyond 0.800 in. SP, or airflow above 571 CFM. Buyers needing speed adjustment or larger duct diameters should look at other models.
Airflow at 0.125 in. SP is 515 CFM
At 0.125 in. SP the fan produces 515 CFM, dropping to 459 CFM at 0.200 in. SP and 347 CFM at 0.375 in. SP. At 0.500 in. SP output is 231 CFM and at 0.800 in. SP it falls to 57 CFM. This pressure-to-flow curve determines whether the fan can overcome the resistance of your specific duct layout.

Questions about this item
How do I install the 10 inch inline duct fan and what step is often missed?
Mount the steel housing inline with 8 inch duct using clamps or tape, wire the 120 V supply to the 1.5 A motor, and seal every joint — the step most often missed is sealing the housing-to-duct connections, which lets static pressure leak and drops CFM from 571 toward 521 at 0.100 in. SP.
What maintenance will the 2550 RPM motor need later?
The single-speed motor runs on sealed bearings; plan to vacuum dust from the impeller and housing once a year and listen for bearing noise — if the fan slows or vibrates, replace the entire motor assembly rather than trying to lubricate it.
At what static pressure does airflow fall off sharply during sustained use?
Airflow drops from 571 CFM at 0.000 in. SP to 231 CFM at 0.500 in. SP and only 57 CFM at 0.800 in. SP, so the practical limit appears around 0.500 in. SP where the curve steepens and the 188 W motor can no longer maintain useful flow.
