Rectangular OEM Blower 1700 RPM

This Dayton blower is a direct-drive unit built for high-temperature environments. It suits OEM equipment builders and maintenance teams who need a compact, forward-curved wheel assembly that arrives fully assembled. The single-phase motor runs at 1700 RPM to deliver consistent airflow in industrial machinery or commercial ventilation systems.

Check phase and static-pressure needs

Verify that your installation provides a single-phase power supply compatible with the motor. Confirm the duct static pressure your system will present so the blower can meet the required airflow; the unit produces 227 cfm at .000 in SP, 210 cfm at .100 in SP, 134 cfm at .250 in SP, 162 cfm at .400 in SP and 110 cfm at .500 in SP.

Steel housing and direct-drive mounting

The steel housing resists heat and corrosion in demanding settings. Direct-drive construction eliminates belt maintenance and reduces vibration, while the assembled forward-curved wheel simplifies installation in rectangular ductwork or equipment enclosures.

Questions about this item

What is included with the blower and what must be purchased separately?

The unit ships assembled as a direct-drive OEM blower with a forward-curved wheel. No drive package is included, so mounting hardware and any required ducting or wiring must be sourced separately.

How do I choose between the airflow ratings at different static pressures?

Match the static pressure of your system to the listed points: 227 cfm at 0.000 in SP, 210 cfm at 0.100 in SP, 162 cfm at 0.400 in SP, 134 cfm at 0.250 in SP, and 110 cfm at 0.500 in SP. Select the figure that corresponds to your duct resistance.

What does the 1700 RPM rating mean for actual airflow in my equipment?

At 1700 RPM the blower delivers up to 227 cfm in free air. In a real installation airflow drops as static pressure rises — for example 210 cfm at 0.100 in SP and 110 cfm at 0.500 in SP — so the installed output depends on your system resistance.
