The hollow top cover at least partially defines therein an electronics bay, floor vents configured to admit a portion of the filtered airstream into the electronics bay as a cooling airstream, at least one primary exhaust port for discharging the filtered airstream to a surrounding ambient environment, and at least one secondary exhaust port for discharging the cooling airstream to the surrounding ambient environment. The electric circuit is positioned in the electronics bay within the cooling airstream.
