The parts of an AHU

An air handling unit (AHU) is a critical component of a pharmaceutical industry’s heating, ventilation, and air conditioning (HVAC) system. It’s also known as the heart of clean room system.

Air Intake – The AHU draws in outside air to be treated and distributed indoors once it has passed through the AHU’s filters and cleaned.

AHU Filter – The filter traps the particles and pollutants in the air, depending on the type of filter used and what is contaminating the air.

AHU Fan – The fan pushes the clean air out of the AHU through the ventilation and air conditioning ducts to distribute the fresh, cleaned air into the building.

Heat Recovery System – This part allows to pre-heat fresh air in winter.

Cooling Coil – This cools the air as it passes through the system.

Silencers – AHUs can be rather noisy, so silencers reduce the noise from loud elements of the AHU when it is operating.

Plenums – These boxes bring in, remove and distribute air.
