SKU CH-TYZN-6HP9A

ECM direct-drive motor converts exhaust fans to variable-speed operation with included speed controller

  • Variable-speed control for precise airflow
  • 1/2 HP ECM motor delivers efficient power
  • 115 V single-phase supply suits standard wiring
  • 1725 RPM nameplate speed for reliable operation
  • Compatible with multiple Dayton blower models

Direct-Drive ECM Motor

The Dayton 43Y137 is a single-phase ECM direct-drive motor rated at 1/2 hp and 115 V. It runs at a nameplate speed of 1725 RPM and includes a speed controller. This unit is designed for technicians converting an existing exhaust fan to variable-speed operation.

Half-Horsepower Capacity

At 1/2 hp the motor comfortably drives compatible exhaust-fan wheels within its rated speed range. The integrated controller allows speed reduction for lower airflow demand, but the motor reaches its limit at the 1725 RPM nameplate rating and cannot exceed that mechanical ceiling.

Compatible Model Range

The motor is specified for use with models 16D518, 43Y140, 5DVT3, 6RJU4, 6RJU5, 6RJU6, 6RJU7, 6RJU8 and 6RJU9. Installers working with other fan assemblies must verify fitment separately, as the supplied speed controller and mounting pattern are matched to this listed range only.

Questions about this item

Will this 115 V motor fit the existing 16D518 blower housing I already own?

The motor is listed for use with 16D518, 43Y140, 5DVT3 and the 6RJU4 through 6RJU9 models, so it should mount to your current housing.

How can I verify the motor is running at the rated 1725 RPM after installation?

Use a handheld tachometer on the shaft; the nameplate speed is 1725 RPM at 115 V single-phase input.

Does the package include the speed controller or must I order it separately?

The manufacturer highlights state "Includes Speed Controller", so the controller ships in the same box.
