Direct-drive OEM blower for industrial airflow

The Dayton 70214931JS is a direct-drive blower rated at 2870 RPM, built for OEM integration in equipment that requires consistent air movement. Its forward-curved wheel and assembled drive package suit manufacturers and maintenance teams fitting or replacing blower units in commercial systems.

Assembled drive package removes installation steps

The unit ships with the drive package included and fully assembled, so installers can mount and wire it without separate component assembly. Forward-curved wheel geometry delivers the published airflow curve across the listed static-pressure points.

70 cfm at zero static pressure defines capacity

At 0.000 in SP the blower moves 70 cfm, falling to 65 cfm at 0.100 in SP, 50 cfm at 0.400 in SP and 45 cfm at 0.500 in SP. Buyers who need higher free-air delivery or a different pressure curve should select another model.

Questions about this item

How often will the direct-drive motor on the Dayton 70214931JS need service?

With no belts or couplings to wear, the direct-drive design only requires periodic bearing lubrication and wheel cleaning to maintain the 2870 RPM rating.

At what static pressure does airflow on the Dayton 70214931JS start to drop off sharply?

Airflow falls from 70 cfm at .000 in SP to 45 cfm at .500 in SP, so the steepest decline appears between .400 in SP (50 cfm) and .500 in SP (45 cfm).

How much heat does the Dayton 70214931JS add to the airstream during continuous operation?

As a high-temperature forward-curved blower running at 2870 RPM, it moves 65 cfm at .100 in SP while the motor heat stays in the housing, not the supply air.
