Globally, heating, ventilation, and air conditioning (HVAC) systems have become a core component of various building and cleanroom projects. Climate conditions, energy policies, and regulatory standards vary significantly across countries and regions, directly impacting the design and application of Air Handling Units (AHU). Whether in hospital operating rooms, pharmaceutical factories, or electronics manufacturing plants, Industrial Air Handling Units are crucial for maintaining air quality and a stable environment.

The Fan Filter Unit​ (FFU) is also a necessary part of cleanrooms. Its distinctive structure can be easily connected in modular and is utilized in cleanrooms, clean benches, clean production lines, and prefabricated cleanrooms, as well as Class 100 cleanrooms. The FFU also uses an internal filter (primarily) and the high-efficiency filter. The air passes through a fan, is filtered, and is spread evenly with the speed of 45 m/s with a 20 percent deviation, which provides high levels of cleanliness in all environments. 

The air filtration system is important in Clean Room Construction and maintenance in regard to the quality of the environment. It is becoming a dream match for industries like pharmaceuticals, electronics, and biological laboratories because the innovative design of the bottom-detachable FFU Fan Filter Unit is easy to maintain and has high filtration standards. Using a combination of the high efficiency of filtration technology of the HEPA FFU, along with the bottom-detachable structure, the operators find it much easier to perform maintenance and replacement, thus enhancing the overall operational efficiency.

In modern, high-standard Clean Room Environments, air cleanliness and contamination control are crucial for ensuring product quality and process safety. Purification equipment such as air showers, cargo showers, transfer windows, high-efficiency air vents, and clean benches, as core components of dust-free workshops and cleanrooms, not only effectively removes dust particles from the air and surfaces but also prevents contamination from entering critical areas, thereby ensuring a safe and stable production environment. This article will detail the characteristics, functions, and application scenarios of various types of purification equipment, helping companies to rationally select and configure cleanroom equipment and improve the overall cleanliness of their production environments.
