Dayton
Dayton 450Z04 Inline Centrifugal Duct Fan 4 in
A 4-inch inline centrifugal duct fan delivering 147 CFM at zero static pressure and 134 CFM at 0.100 in. SP, powered by a 120 V, 0.38 A, 43 W motor at 2580 RPM
- Fits 4 in duct for direct installation
- 147 CFM at zero static pressure for strong airflow
- 43 watts maximum draw keeps energy use low
- Steel housing resists damage in duct runs
- Single-speed 2580 RPM motor gives consistent output
Four-inch inline centrifugal duct fan
The Dayton 450Z04 is a steel-housed inline centrifugal duct fan built for four-inch ductwork. It runs on 120 volt single-phase power at 0.38 amps and 43 watts with a single-speed motor turning at 2580 RPM. Installers and facility managers use it for supply, exhaust or make-up air in residential and light-commercial ventilation systems.
Sustained airflow across static pressure range
The fan delivers 147 CFM at zero static pressure and maintains 134 CFM at 0.100 in. SP, 133 CFM at 0.125 in. SP, 119 CFM at 0.200 in. SP and 105 CFM at 0.250 in. SP. Output falls to 90 CFM at 0.375 in. SP, 75 CFM at 0.400 in. SP and 0.450 in. SP, 58 CFM at 0.500 in. SP, 45 CFM at 0.600 in. SP, 29 CFM at 0.750 in. SP and 14 CFM at 0.800 in. SP.
Simple wiring and duct connection
A single-speed motor means only a live, neutral and ground connection are required. The nine-inch housing diameter matches standard four-inch duct connectors, so no reducer is needed. The steel housing adds weight compared with plastic units, so bracket spacing must follow local code. Buyers who need variable-speed control or EC-motor efficiency cannot meet those needs with this model.

Questions about this item
How loud is the 43 W motor when it runs continuously at 2580 RPM?
The single-speed motor draws 0.38 A at 120 V and runs at 2580 RPM; no sound-pressure figure is published, so expect typical inline-centrifugal noise at that power level.
What ducting and electrical supply must I already have to install this 4 in fan?
You need 4 in diameter ductwork and a 120 V circuit capable of 0.38 A; the steel housing measures 9 in long by 9 in wide for mounting clearance.
Will the 147 CFM free-air flow still reach my older 4 in duct runs that have 0.250 in static pressure?
At 0.250 in SP the fan delivers 105 CFM, dropping to 58 CFM at 0.500 in SP and 14 CFM at 0.800 in SP, so performance depends on your exact duct resistance.
