JK45 Single Motor Primary Mine Ventilation Booster Fans

DK40 mine ventilation booster fan is a primary fan that is in series with another primary fan.

Without the booster fan operation, the total mine airflow will fall significantly. Booster fans are typically installed as mine develops and primary fan no longer has the pressure or flow capability to service increased resistance of operation.

In this sense, booster fan operates as an integral and “symbiotic” unit with the original primary fan to provide sufficient total airflow for mine.
