Dayton 450Z19 12-inch duct blower

The Dayton 450Z19 is an inline centrifugal blower built for 12-inch round ductwork. Its steel housing measures 16 inches in diameter and 13 inches long, making it a compact choice for supply or exhaust runs in residential and light-commercial ventilation systems.

120 V single-speed wiring and static-pressure curve

The unit runs on a 120 V supply drawing up to 2.4 A and 312 W at 2780 RPM. One fixed speed simplifies wiring, while the published curve shows airflow from 1038 CFM at .000 in. SP down to 103 CFM at .800 in. SP, letting installers match duct resistance without a variable-speed controller.

1038 CFM free-air capacity with measurable drop-off

At zero static pressure the blower moves 1038 CFM, falling to 954 CFM at .100 in. SP and 731 CFM at .250 in. SP. By .500 in. SP output is 419 CFM and at .800 in. SP only 103 CFM remains, so the fan suits short, low-resistance duct runs but not long or heavily filtered systems.
