Abstract
A work machine, such as a skid steer loader or a compact track loader, includes an air intake assembly for a heating, ventilation, and air conditioning (HVAC) unit. A conduit integrated into a structure supporting a roof over an operator cab accepts air and water from the atmosphere through an air inlet proximate the roof. A debris outlet downstream in the conduit allows gravity to return the water to the environment. Between the air inlet and the debris outlet, an orifice in the conduit connects to an air duct through which the air may be diverted by suction from the HVAC unit. An air filter at the end of the air duct removes remaining particulates from the air prior to conditioning by the HVAC unit. Sizing the cross-sectional areas of the air path to exceed a cross-sectional area of an inlet to the air filter and providing a substantially straight air path avoids resistance to air flow, resulting in efficient intake of cleaner air.
