Dayton 70213467X OEM Blower Identity

The Dayton 70213467X is a square OEM blower built for direct-drive integration in HVAC or equipment enclosures. It ships fully assembled with its drive package included and operates at 3020 RPM on single-phase power. Buyers needing a belt-driven or variable-speed alternative will not find that flexibility here.

Direct-Drive Forward-Curved Wheel

The forward-curved wheel and direct-drive arrangement are the defining specification; they fix the speed-torque relationship and eliminate belt maintenance. Wheel diameter is 3 3/4 in and the blower is rated for high-temperature service. Installers who require a different wheel profile or a separated motor mount cannot use this unit.

Airflow Capacity and Static-Pressure Limits

At zero static pressure the blower moves 140 cfm, falling to 136 cfm at .100 in SP, 119 cfm at .400 in SP and 110 cfm at .500 in SP. The 105 cfm rating at .250 in SP marks the practical midpoint for ducted installations. Systems demanding sustained flow above 140 cfm or operation beyond .500 in SP will exceed this blower's envelope.

Questions about this item

What does the 3020 RPM rating mean for actual airflow?

At free air the blower moves 140 cfm, dropping to 136 cfm at 0.100 in SP, 119 cfm at 0.400 in SP and 110 cfm at 0.500 in SP.

What drive interface does the 70213467X use and what limits it?

Direct-drive single-phase motor couples the wheel directly to the shaft, so speed and torque are fixed by the 3020 RPM design.

What mounting space does the 3 3/4 in wheel need?

The forward-curved wheel is 3 3/4 in diameter and the unit ships fully assembled, so allow at least that diameter plus clearance for the housing.
