Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating.
Air Handling Systems for Pharmaceutical Industries Impeccable Hygiene and Outstanding Room Conditions Hygiene in the pharmaceutical sector is a self-evident prerequisite to the quality of pharmaceutical products. Avoiding pathogens transmitted through the air is top priority. A hygienically impeccable and comfortable room climate is essential during development or production processes in the pharmaceutical sector. Air handling systems are, therefore, indispensable for reducing or avoiding airborne pathogens. AHUs in cleanrooms performs the following basic functions:
1. Maintain room pressure (delta p) – Areas that must remain cleaner than surrounding areas must be kept under a positive pressurization. Therefore the AHU must provide more air into the cleaner space than is mechanically removed from that same space.
2. Maintain space moisture (relative humidity) – Humidity is controlled by cooling air to dew point temperatures or by using desiccant dehumidifiers. Humidity can affect the efficacy and stability of drugs and is sometimes important to effectively mould the tablets.
3. Maintain space temperature – Temperature can affect production directly or indirectly by fostering the growth of microbial contaminants on workers.

AHU has big role in Pharmaceuticals as it circulates air through the whole premises. It supplies fresh and dust free air to the different parts of the factory. It also prevent the microbial contamination in the area as well as controls pressure, temperature and humidity in the area.

AHU mean Air Handling Unit. In Pharmaceutical Industry AHU plays a vital role. AHU is mainly used to control temperature , humidity , air pressure . AHU also prevent microbial contamination. AHU supplies fresh and dust free air to the different parts of the industry.

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 and improvement of production quality of the pharmaceutical product.
