Inline centrifugal duct fan with steel housing fits 6 in duct and delivers 213 CFM at zero static pressure
- Delivers 213 CFM free-air flow for strong ventilation
- Maintains 193 CFM at 0.1 in. static pressure for ducted runs
- Steel housing resists damage in tough environments
- Single-speed 120 V motor draws only 0.38 A for low energy cost
- Compact 9 in housing fits 6 in duct for tight installs
9-inch inline centrifugal blower
The Dayton 450Z08 is a steel-housed inline centrifugal duct fan built for 120 V single-phase supply. It draws a maximum of 0.38 A and 47 W at 2390 RPM. The unit fits 6-inch ducting and offers a single-speed configuration for straightforward exhaust or supply airflow in residential or light-commercial ventilation.
Static-pressure airflow limits
Airflow falls from 213 CFM at free discharge to 193 CFM at 0.100 in. SP, 175 CFM at 0.125 in. SP and 171 CFM at 0.200 in. SP. Higher resistance cuts delivery further: 150 CFM at 0.250 in. SP, 129 CFM at 0.375 in. SP, 108 CFM at 0.400 and 0.450 in. SP, 86 CFM at 0.500 in. SP, 63 CFM at 0.600 in. SP, 42 CFM at 0.750 in. SP and 21 CFM at 0.800 in. SP.
Replaces underperforming inline fans
This blower upgrades installations where an existing inline fan cannot maintain required CFM against measured duct static pressure. The jump is worth it when system resistance sits between 0.100 and 0.500 in. SP and the current unit delivers below the 193–86 CFM range shown here. It does not suit builders who need variable-speed control or multi-speed operation.

Questions about this item
Which airflow rating should I use when sizing this fan for my duct run?
Use the CFM value that matches your system's static pressure; at 0.250 in. SP the fan delivers 150 CFM, while at 0.500 in. SP it drops to 86 CFM.
What does the 213 CFM figure represent once the fan is installed in a real duct system?
213 CFM is the free-air rating at 0.000 in. SP; actual airflow will be lower — for example 175 CFM at 0.125 in. SP or 108 CFM at 0.400 in. SP.
The fan runs on 120 V — what current draw should I plan for on the circuit?
The motor draws a maximum of 0.38 A at 120 V, which corresponds to the listed 47 W maximum wattage.
