An Air Handling Unit (AHU) is an essential part of heating, ventilation, and air conditioning (HVAC) systems. It is designed to regulate and circulate air throughout a building or facility. The AHU helps maintain a comfortable environment by controlling air temperature, humidity, and quality. This unit typically consists of fans, heating/cooling coils, filters, and dampers, all working together to ensure the air is clean, fresh, and at the right temperature.

The main function of the AHU is to take in air from the outside, condition it, and then distribute it to different parts of a building. The air is first filtered to remove dust and pollutants, making it healthier to breathe. It can then be heated or cooled depending on the weather and the indoor requirements. Once the air is conditioned, the AHU pushes it through ductwork to various spaces in the building.

Air Handling Units are commonly used in commercial buildings, hospitals, factories, and other large facilities. They are vital for maintaining good indoor air quality, energy efficiency, and overall comfort. By regulating airflow and temperature, AHUs help improve the overall environment, making it more pleasant and productive for everyone inside. Regular maintenance of an AHU is important to ensure its efficiency and longevity.
