Browning 4L390 39" FHP Non-Notched V-Belt

The Browning 4L390 39" Non-Notched V-Belt is a fractional horsepower drive belt used for power transfer in equipment and similar light-duty mechanical systems. It is commonly found in blower assemblies, fan drives and air handling units, where consistent rotational motion is required in HVAC systems. The belt transfers motor torque, to pulleys through frictional contact enabling controlled movement of fans and blowers. It is fitted around matched sheaves, and tensioned to maintain grip during operation. This component supports steady airflow delivery, reduces slip between drive elements, and assists mechanical motion in ventilation and cooling equipment.
