Abstract
A fan drive checking system, for an air conditioning system in a clean room having a fan filter unit (FFU), includes a flow sensor for sensing air flow inside a housing of a FFU. The sensor provides a sensor signal indicative of normal and adverse flow conditions in the housing. A control portion in data communication with the sensor outputs a control signal responsive to the sensing signal. An alarm in data communication with the control portion provides a warning when the control signal indicates the adverse flow condition.
