Dayton 2C647 Direct Drive Blower — Application
The Dayton 2C647 is a high-temperature direct-drive blower with a 5-1/4 in wheel diameter designed for OEM replacement in equipment that moves heated air. It delivers 134 cfm at .000 in SP and maintains 79 cfm at .500 in SP for consistent airflow under load.
Verify Voltage and Mounting Before Installing
Confirm the supply voltage matches the motor nameplate and that the existing housing accepts a forward-curved wheel with direct-drive mounting. The assembled unit includes no separate drive package, so shaft alignment and bolt pattern must match the original blower exactly.
Thermal Performance and Power Draw in Service
Rated for high-temperature operation, the blower moves 126 cfm at .100 in SP and 116 cfm at .250 in SP without derating. Direct-drive construction eliminates belt losses and reduces mechanical noise, while the forward-curved wheel keeps power draw steady across the published static-pressure range.

Questions about this item
What comes with the Dayton 2C647 blower and what must be purchased separately?
The unit arrives assembled as a direct-drive blower with a 5-1/4 in forward-curved wheel. No drive package is included or required for this model.
How do the airflow ratings help me choose the right version for my static pressure?
At 0.000 in SP the blower delivers 134 cfm, at 0.100 in SP it provides 126 cfm, at 0.250 in SP it gives 116 cfm, at 0.400 in SP it supplies 96 cfm, and at 0.500 in SP it produces 79 cfm.
What does the 134 cfm headline figure mean once the blower is installed in a real system?
That 134 cfm is the free-air rating at zero static pressure. In practice, airflow drops as resistance rises — for example, 126 cfm at 0.100 in SP and 79 cfm at 0.500 in SP — so actual output depends on your ductwork and filters.
