An air intake system for a cab and engine of a vehicle is shown and described. In a preferred embodiment, dry, ambient air is provided to the cab and engine through a duct that is mounted to an inner surface of a vehicle hood such that the hood forms a top surface of the duct. The duct is relatively narrow across the width of the hood and flares into an air chamber on either side of the hood. An air inlet opening is provided on both sides of the hood such that outside air is drawn into the air chambers. The velocity of the air drops as it passes into and through the air chambers, causing the moisture in the air to separate and drain from the air chambers through an evacuator valve provided in the bottom surface of each chamber. Two openings are provided in the bottom surface of the duct. One opening sealingly engages an opening in the engine air cleaner and the second opening sealingly engages a cab air intake duct, when the hood is in a closed position. A noise suppression baffle is located in the duct adjacent the opening to the engine air intake to help isolate engine noise from the cab, and to prevent the engine air intake from drawing an unacceptable amount of air from the cab air intake.

An air intake system for a vehicle comprising: an air duct depending from an inner surface of a vehicle hood, the air duct being provided with a first opening to allow fluid communication between the air duct and an engine air intake of the vehicle, and being provided with an air chamber depending from the inner surface of the vehicle hood that is in fluid communication with ambient air which contains moisture, the air chamber being adjacent an ambient air intake provided in the vehicle hood, the air chamber being provided with a bottom surface and with a second opening to allow fluid communication between the air chamber and a cab of the vehicle, the air chamber having a sufficiently large volume so that a velocity of the ambient air as it enters the air chamber drops sufficiently to cause a substantial amount of the moisture to separate from the air and drop to the bottom surface of the air chamber, whereby substantially dry ambient air is provided to the engine and the cab.
