An Air Handling Unit (AHU) is considered to be one of the most important parts of HVAC systems. An AHU is used in industrial and commercial buildings, pharma, hospitals, clean rooms, and laboratories for processing and distributing filtered air.
With the increasing demands for good indoor air quality, energy-saving processes, and efficient environment control from industries in India, there is also a need for effective AHUs.
The knowledge of the working principle, types, components, cost, and installation process will help you make your decision when choosing an AHU for either an existing HVAC system or a new HVAC system.
In BionicsRO, we supply customized AHUs in India according to your needs.
Air Handling Unit (AHU) is an integral part of the HVAC system which performs filtration, heating, cooling, humidification, dehumidification, and distribution of air in buildings in order to keep the indoor air quality, temperature, and humidity.
The key function of an Air Handling Unit is to maintain comfort, hygiene, and control of indoor conditions.
Short Answer
In its functioning, an Air Handling Unit takes fresh or return air, filters it from contaminants, treats the air with heating/cooling coils, and distributes the treated air within the building.
The typical sequence of operation for an Air Handling Unit usually follows:
The AHU takes air from outside (fresh air) and returns air (air already circulated indoors) through air intake dampers.
It filters the air to eliminate dust, particles, pollution, bacteria, and any other contaminant from the air.
Conditioning can be through cooling/ heating coils depending on the requirements of the environment.
This is done via the use of a humidifier/dehumidifier depending on the intended usage of the air.
AHU diagram illustrates the route that the air flows in an Air Handling Unit together with all its main components. It gives people a clear understanding of how fresh air is filtered and distributed inside a structure.

There are several key parts to a typical AHU schematic diagram that include the following:
Comprehending the schematic diagram of AHUs can prove to be very useful.
Various buildings need various designs of AHU depending on airflow demand and environment.
This is a compact AHU where all components are enclosed together in a unit.
Constructed using several sections and modified depending on project needs.
This AHU is fitted on rooftops to conserve floor area of a building.
This unit supplies 100% fresh air to a building interior.
This AHU finds its application in the manufacturing industries such as biotechnology, electronic engineering, and health care industry.
This unit finds its application in food processing industries.
Understanding Air Handling Unit parts is essential for maintenance and efficient operation.

An air handling unit (AHU) is an HVAC device that delivers treated air into the building, at the same time maintaining air quality, temperature, and humidity inside the building.
Its mechanism is such that it supplies filter treatment of air entering the building, controls temperature and humidity, and finally delivers treated air into the ducting system.
They include filters, fans, cooling coil, heating coil, dampers, humidifier, and controls.
An AHU caters to larger areas with air conditioning and supply of fresh air, whereas an FCU offers individual temperature regulation in specific areas.
Some examples of industries which employ AHUs are pharmaceutical industry, hospitals, labs, food industry, commercial buildings, and manufacturing industries.
The price depends on the capacity of AHUs, filtration needs, and other related features. Usually, industrial and cleanroom AHUs need quotes.
Cleanroom AHU with HEPA filtration and precise control of the environment is usually used in the pharmaceutical industry.
