What is an Air Handling Unit? It is a large metal box that has a blower, heating or cooling parts, dampers and sound absorbers. Air Handling Units are connected with the duct ventilation system. The ducts function to distribute the conditioned air across the premises and return it to the Air Handling Unit. AHUs are essential to maintain optimal temperatures in premises. The components and design of the Air Handling Units can differ as per the use.

Hygienic Air Handling Units are used in surgical operating rooms, clean rooms, food facilities, health facilities and laboratories etc. The purpose of hygienic air handling unit is to control the conditions of the premises to create an environment that inhibits bacteria growth and spread.

The differences between the AHUs and hygiene units lie in hygienic components and smooth surfaces meant to avoid humidity and development of micro-organisms; structure and casing as per the accepted norms; hygienic sound absorbers in the units that help reduce the particles in the ductwork; filtration efficiency; technology to reduce the growth and spread of micro-organisms. Hygiene units not only control power consumption but are easier to install too.
