AHU for Pharmaceutical Clean Room

In pharmaceutical clean rooms, air handling units (AHUs) play a crucial role in maintaining the required level of cleanliness and controlling the environmental conditions.

HEPA or ULPA Filters: AHUs in pharmaceutical clean rooms should be equipped with high-efficiency particulate air (HEPA) or ultra-low penetration air (ULPA) filters. These filters are capable of removing particles as small as 0.3 micrometers and are essential for maintaining a sterile environment.

Airflow Control: AHUs should have variable air volume (VAV) control or other mechanisms for controlling the airflow rates. This helps in adjusting the air change rates based on the cleanliness requirements of the specific clean room area.

Positive Pressure: Clean rooms typically maintain positive pressure compared to surrounding areas to prevent the entry of contaminants. AHUs should be designed to maintain this positive pressure consistently.

Temperature and Humidity Control: AHUs must be capable of controlling both temperature and humidity levels within the clean room. Maintaining a stable temperature and humidity is crucial for certain pharmaceutical processes and the comfort of personnel working in the clean room.

Material of Construction: The construction materials of AHUs should be compatible with the pharmaceutical environment. Stainless steel or other non-corrosive materials are often used to prevent contamination.

Seals and Gaskets: AHUs should be equipped with high-quality seals and gaskets to prevent any air leakage, ensuring that the clean room maintains its required cleanliness levels.
