The definition of a modular air handling unit (MAHU) can be a little tricky to understand at first glance, but it is actually quite simple. A MAHU is an air handling unit that is designed to be self-contained, meaning it can be used as a stand-alone unit or integrated into a larger system. MAHUs typically consist of a set of components, such as a fan, filter, heat exchanger, plenum, and/or an evaporator coil, that are all engineered to work together to provide efficient and effective air conditioning, ventilation, and heating. MAHUs are designed to provide flexible solutions that can be tailored to fit the needs of specific applications. Because MAHUs are designed to be modular, they are often easy to install, maintain, and upgrade. Additionally, MAHUs can be combined with other components, such as an air compressor, to further customize the air-handling unit to meet the specific needs of a particular
