Claim:
1. A ventilation system for enclosing a turbomachine assembly component, the ventilation system comprising: an enclosure defining an interior; an air inlet circuit in fluid communication with the interior for flowing air into the interior; an air outlet circuit in fluid communication with the interior for flowing air from the interior; a fan disposed within one of the air outlet circuit or the air inlet circuit; a motor in operable communication with the fan for driving the fan; a mechanical measurement device, the mechanical measurement device operable to measure a flow characteristic of the air within one of the air inlet circuit or the air outlet circuit; an electrical measurement device, the electrical measurement device in communication with the motor and operable to measure an electrical characteristic of the motor; and a controller, the controller operable to indicate that a minimum air flow threshold has been reached if the flow characteristic is below a predetermined flow threshold and the electrical characteristic is below a predetermined electrical threshold, wherein the controller compares the electrical characteristic to the predetermined electrical threshold only if the flow characteristic is below the predetermined flow threshold.
