Dayton 450Z20 Inline Centrifugal Duct Fan 10 in
Inline centrifugal duct fan moves up to 630 CFM through 10-inch ducting at 120 V with a 2550 RPM motor
- Delivers 630 CFM at zero static pressure for strong airflow
- Maintains 570 CFM at 0.100 in. SP for ducted runs
- Steel housing resists damage in commercial installations
- Single-speed 2550 RPM motor simplifies wiring
- Draws 1.7 A at 120 V for standard circuit compatibility
Inline Centrifugal Duct Fan 10 in
The Dayton 450Z20 is an inline centrifugal duct fan built for 10 inch round ductwork. Its steel housing measures 13 inches in diameter and 10 inches long. It runs on 120 volt single-phase power and draws up to 1.7 amps at 197 watts. The single-speed motor turns at 2550 RPM for straightforward exhaust or supply applications.
Airflow across static pressure range
At zero static pressure the fan moves 630 CFM, falling to 570 CFM at 0.100 in. SP and 569 CFM at 0.125 in. SP. Output drops to 507 CFM at 0.200 in. SP, 446 CFM at 0.250 in. SP and 382 CFM at 0.375 in. SP. Higher resistance cuts flow further to 319 CFM at 0.400 and 0.450 in. SP, 249 CFM at 0.500 in. SP, 191 CFM at 0.600 in. SP, 126 CFM at 0.750 in. SP and 63 CFM at 0.800 in. SP.
Duct size and electrical supply check
Verify that your duct run uses 10 inch diameter connections to match the fan inlet and outlet. Confirm the circuit can deliver 120 volts and handle the 1.7 amp draw with appropriate wiring and breaker sizing. Ensure the 13 inch housing diameter and 10 inch length fit the available mounting space. This unit offers only one speed, so variable airflow control is not possible.

Questions about this item
How loud is the 2550 RPM motor when the fan runs continuously?
The motor spins at 2550 RPM on a single speed; Dayton does not publish a decibel rating, so exact noise level is not available.
What ducting and electrical supply must I already have to install this 10 in duct fan?
You need 10 in diameter ductwork and a 120 V circuit capable of 1.7 A (197 W).
Will the 630 CFM at 0.000 in. SP still move air through my older 10 in galvanised duct runs?
Yes, the fan delivers 630 CFM at zero static pressure and 570 CFM at 0.100 in. SP, suitable for typical 10 in duct systems.
