HVAC ventilation exhaust for a 12-story building An axial belt-drive exhaust fan serving an underground car park. This exhaust fan's operation is interlocked with the concentration of contaminants emitted by internal combustion engines. Mechanical, or forced, ventilation is provided by an air handler (AHU) and used to control indoor air quality.
Fan (machine) A household electric fan. A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner.

In the summer, the inside air cools the warmer incoming supply air to reduce ventilation cooling costs. [5] This low-energy fan-and-motor ventilation system can be cost-effectively powered by photovoltaics, with enhanced natural convection exhaust up a solar chimney - the downward incoming air flow would be forced convection .
