Motor Speed Controllers

Need to slow a loud blower, bump CFM for static, or keep a system running after an ECM quits? Find fast, budget-friendly fixes with a motor speed controller—from simple ECM speed control to ECM-to-PSC conversion.

Pick the controller that matches your motor type (ECM vs. PSC), voltage, and horsepower, and get back to proper airflow without a full blower changeout.

Fine-Tune Airflow and Rescue Failed ECMs

Swap a failed variable-airflow ECM to a PSC while keeping multi-speed operation with the QwikProducts QwikSwap V3 QT6104.

Convert constant-torque X13/SelecTech ECM blowers to PSC using the ICM716 ECM-to-PSC controller or the value-priced ICM715. Match HP and voltage for a clean retrofit.

For GE 2.3 ECM motors, set or trim blower speed with ICM708 (flow index 0–100%), tie into control signals with ICM711, or add automated control/monitoring with ICM713.
