K40 Single Motor Mine Ventilation Booster Fans

A 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.

Mine booster fans are technically main fans which are installed underground to maintain required airflow by overcoming the mine resistance. Booster mine ventilation fans can reduce the pressure of the main fan and decrease system leakage and total
