Abstract
An outdoor equipment cabinet includes a housing with an equipment compartment therein. An intake air vent and an exit air vent are formed in the housing. A fan is mounted within the housing for pulling air into the intake air vent, moving an air stream through the equipment compartment, and pushing air out of the exit air vent. A membrane is disposed adjacent the intake air vent. The membrane allows air to pass therethrough, but resists the passage of water and contaminants therethrough. In some embodiments, a baffling plate is disposed to direct the air stream within the equipment compartment, and/or the fan speed is controlled by a temperature sensor, and/or a clogging of the membrane is monitored and reported, and/or the intake air vent is located in a first door and the exit air vent is located in a second door of the cabinet.
