Abstract
A cab for a work vehicle includes: walls enclosing a cab environment; a door coupled to one of the walls, one of the walls or the door comprising a vent opening; a heating, ventilation, and air conditioning (HVAC) system coupled to the cab environment and configured to regulate a temperature and a pressure of the cab environment; and a pressure control flap associated with the vent opening and comprising a pressure-relief opening and a magnetic portion that is configured to hold the flap closed when the pressure of the cab environment is below a threshold pressure and allow the pressure to open the flap when the pressure exceeds the threshold pressure.
