What components are typically included in a commercial Air Handling Unit (AHU)?

Supply fan, coil, filters, and outlet and inlet dampers
Exhaust fan, coil, filters, and outlet and inlet dampers
Supply fan, coil filters, and humidifier
Exhaust fan, coil, filters, and humidifier

The correct answer is: Supply fan, coil filters, and humidifier

The components typically included in a commercial Air Handling Unit (AHU) are critical for its function of conditioning and circulating air within a building. The correct choice highlights the inclusion of the supply fan, coil, filters, and humidifier. The supply fan is essential as it moves the air through the system, ensuring proper circulation and distribution throughout the space. The coil, which can be either heating or cooling, is responsible for regulating the temperature of the air before it enters the occupied spaces. Filters play a crucial role in improving indoor air quality by removing dust, allergens, and other particulates from the air. In addition to these components, a humidifier is often part of an AHU to maintain optimal humidity levels within the indoor environment, particularly in spaces where comfort and health are prioritized. Other options focus on exhaust components or combine elements in a way that does not accurately reflect the typical assembly of an AHU designed for handling the supply of conditioned air to spaces.
