Allied Air 23v89 Ecm Constant Torque Blower Motor 1/2 Hp

Product Description

The ALLIED AIR 23v89 is a pre-programmed ECM constant torque blower motor designed for residential forced-air HVAC systems. Rated at 1/2 horsepower and operating on 115 volts AC, this motor delivers five selectable speed taps covering a range of 550 to 1300 RPM. ECM technology provides significantly improved energy efficiency over standard PSC motors by maintaining constant torque output as static pressure in the duct system changes. The pre-programmed design eliminates field programming steps, allowing a faster drop-in installation for qualified HVAC technicians replacing a failed blower motor.

This motor is suited for residential air handlers, furnaces, and fan coil units that require an ECM constant torque replacement. The five-speed configuration allows the installing technician to match the motor tap to the original equipment blower speed table. Applications include heating and cooling airflow delivery in ducted split systems and packaged equipment where the OEM specified a constant torque ECM motor of equivalent horsepower and voltage rating.

Key Features

• ECM constant torque technology maintains airflow performance as duct static pressure varies
• Pre-programmed from the factory — no external programmer or interface module required
• Five speed taps spanning 550 to 1300 RPM for flexible airflow matching
• 1/2 HP output rated at 115 volts AC for broad residential system compatibility
• Drop-in replacement format reduces labor time versus variable-speed ECM alternatives

Compatibility

Designed as an OEM-style replacement ECM constant torque blower motor for residential forced-air HVAC equipment specifying a 1/2 HP, 115V, 5-speed constant torque motor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the air handler or furnace before removing the existing motor. Verify the replacement speed tap selection against the original equipment blower performance table before energizing the system. Secure all low-voltage control wiring connections per the equipment wiring diagram and confirm the motor mounts correctly in the original blower housing before restoring power.
