- Delivers 150 CFM at zero static pressure
- Maintains 137 CFM at 0.100 in. SP for duct runs
- Single-speed 2620 RPM motor draws only 83 watts
- Steel housing fits 4-inch duct for straightforward installation
- Operates up to 104 °F inlet temperature for reliability
Inline centrifugal duct blower for 4 in ducting
The Dayton 450Z05 is an inline centrifugal duct blower built for 4 in duct diameter. It runs on 120 V single-phase power and delivers up to 150 CFM at zero static pressure. The single-speed motor spins at 2620 RPM to move air through residential or light-commercial ventilation runs.
Thermals noise and power draw in normal use
The unit draws a maximum of 83 W and 0.69 A while operating. Maximum inlet temperature is rated at 104 Degrees F so the housing stays within safe limits during continuous duty. Airflow falls to 122 CFM at 0.125 in SP and 61 CFM at 0.400 in SP, showing how pressure affects delivered volume.
Steel housing and duct mounting implications
A steel housing provides mechanical rigidity for fixed installations. The 9 in housing diameter and 9 in length fit standard round duct connections without adapters. Single-speed operation means no variable-flow control is built in so airflow is constant whenever the blower is powered.

Questions about this item
How do I install the 4 in duct connection and what step is often missed?
Slide the 4 in duct over the inlet, secure it with a clamp or foil tape, then seal every joint so the fan can reach its 150 CFM rating at .000 in. SP without leakage.
What maintenance will the motor need over time?
The single-speed motor runs at 2620 RPM on 120 V and 83 W; plan to clean dust from the impeller and housing periodically and listen for bearing noise that signals lubrication or replacement.
At what static pressure does airflow drop below useful levels?
Airfall falls to 15 CFM at .750 in. SP and 30 CFM at .600 in. SP, so design the duct run to stay well below .500 in. SP where output is still 45 CFM.
