Specialist Air Treatment
An air handler, or air handling unit (often abbreviated to AHU), is a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to ductwork that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork.
For high-end applications such as, Pharmaceutical and IT Facilities, Communication centres, Server and Computer rooms, Specialist Medical services, Financial centres, Precision air conditioning, Close Air conditioning, Cleanroom Air showers etc, very precise AHU's are needed. Air filtration is always present in order to provide clean dust-free air to the building environment. It may be via simple low-MERV pleated media, HEPA, electrostatic, or a combination of techniques.
