condition survey fanAbove: Deferred maintenance failed fan connection


This photo is self explanatory, this "safety system" had not been checked, the exhaust fan flexible connections have perished (deferred maintenance). The damage was located at the higher air pressure point, near the fan intake means instead of exhausting air from the plant room, outside air will be drawn into the suction side of the fan, reducing exhaust fan effectiveness. The discharge side flexible connection, at highest air pressure, was also perished.

It means the owner has wasting money, paying the electricity charges just to circulate outdoor air.
