Best 10 Standard Ahu Manufacturers in China 2025

Introduction to Standard AHU

A standard Air Handling Unit (AHU) is a crucial component in heating, ventilation, and air - conditioning (HVAC) systems. It is responsible for processing and conditioning the air within a building. An AHU typically takes in fresh air from the outside, filters it to remove dust, pollutants, and other contaminants, and then heats, cools, humidifies, or dehumidifies the air as required. After conditioning, the air is distributed through a network of ducts to different areas of the building, ensuring a comfortable and healthy indoor environment. Standard AHUs come in various sizes and configurations to meet the diverse needs of different buildings, such as commercial offices, hospitals, schools, and industrial facilities.
