HVAC Blower Motor
The CENTURY DL1076 is a direct-drive blower motor built for HVAC air-moving applications. Its permanent split capacitor design delivers 3/4 HP at 1075 RPM on 115 V AC single-phase power. The 48-frame open air-over enclosure and resilient-ring mounting suit all-angle installation.
Three-Speed Operation
Three selectable speeds let the installer match airflow to the system design without changing pulleys or belts. Auto-reset thermal protection interrupts power if the winding temperature exceeds the Class B limit, then restarts the motor once it cools. A 26-inch lead length simplifies wiring to the control board.
Pre-Install Checks
Confirm the supply voltage is 115 V AC at 60 Hz; the motor is not usable at 200 V or 208 V. Verify the shaft rotation direction matches the blower wheel requirement, as the motor runs CW or CCW. Ensure the mounting location stays within the 50 °C maximum ambient temperature rating.

Questions about this item
What maintenance will the open air-over 48 frame motor with 26 in leads need over time?
The open air-over enclosure relies on the air stream it moves for cooling, so the main upkeep is keeping the blower wheel and intake clean to maintain airflow across the windings.
What limit appears first when the PSC motor runs continuously at 1075 RPM and 9.1 amps on 115V?
The automatic thermal protector will trip if winding temperature exceeds the Class B insulation limit at 50 degrees C ambient, which is the first safeguard under sustained load.
How much heat and noise should I expect from the 3/4 HP unit running all day in an HVAC cabinet?
At full load the motor draws 9.1 amps at 115V, and the open air-over design discharges that heat directly into the airstream; audible level is typical for a resilient-ring mounted PSC blower motor.
