Description
The York S1-028-12361-700 Variable Pulley is a precision-engineered OEM component designed to provide adjustable speed control for fans, blowers, and motors in HVAC systems. By allowing changes in the pulley diameter (and thus drive ratio), this variable pulley lets you fine‑tune airflow, motor speed, and system performance — improving comfort, efficiency, and longevity.
