Modular cleanrooms, also known as assembled cleanrooms, are a kind of partial purification equipment specially designed to control the level of air pollution removing pollutants such as micro-particles, harmful gas, bacteria and controlling the indoor temperature and humidity, cleanliness, differential pressure, air velocity, airflow distribution, noise vibration and lighting, and static electricity within a certain required range，and ensure high-precision work or product experiments and manufacturing, which can quickly improve the clean class of the area.

  The cost of modular clean rooms depends on many factors, including ISO classification requirements, area, height, material selection, special needs, and supporting facilities. According to the different needs of customers, corresponding modular clean room solutions and cost budgets can be designed. The main installation components of modular clean rooms are prefabricated in Airkey factory, to realize quick and easy installation on site, which can greatly shorten the construction period and reduce the labor cost of on-site construction. Therefore, the overall cost of modular clean rooms is about 20% lower than that of traditional clean rooms, and the installation period can be saved by 40~50%.

Compared with traditional clean rooms, modular clean rooms have the following advantages:

• Quick installation: Modular clean rooms use prefabricated modules, which are easy and quick to install, greatly shorten the construction period
• Flexible layout: The modular cleanroom design can be customized according to your needs, and the floor plan is more flexible and changeable to meet the ever-changing work needs.
• Slight impact on the on-site environment: Modular clean rooms are only assembled on site, without material cutting and processing, reduces pollution and noise, can maintain a clean working environment.
• Energy saving and environmental protection: Modular clean rooms use advanced energy-saving technologies to effectively reduce energy consumption. At the same time.
• Simple maintenance: Simple daily cleaning & maintenance, providing convenience for your daily operations.
• High cost-efficiency: Modular clean rooms are less expensive and have a shorter installation cycle than traditional clean rooms, therefore, more cost-effective.
• Mobility and scalability: The design of modular cleanrooms takes into account mobility and adjustability. It can be quickly rearranged or expanded according to process requirements, or disassembled and relocated to improve production efficiency and flexibility.

Modular cleanrooms are designed to quickly provide a local clean and controlled environment that meets process requirements. They can be widely used in food processing, electronics, scientific experiments, pharmaceuticals and other fields. In the field of food processing, modular clean rooms can be used as dust-free food workshops to ensure the cleanliness of the food production environment and improve food safety standards; in the field of electronics, dust can cause short circuits in electronic devices and affect performance. Modular clean rooms can create a designated production environment with minimum and controlled particles ; in the pharmaceutical field, modular clean rooms can provide a highly clean production environment to ensure the quality and safety of drugs; in the laboratory field, modular clean rooms provide research spaces that meet specific environmental requirements to ensure the accuracy and reliability of experimental results. In the future, with the accelerated development of downstream industries, modular clean rooms will have an expanded and bigger market.

  The information required for clean room design includes: thepurpose of clean room, thefloor plan and size of clean room, and the configuration requirements of production equipment (the number of production equipment and water and electrical parameters are crucial to the design and calculation of clean room air purification system, HVAC and pressure control system); Industry standards (If the design of the clean room is required to comply with a specific industry standard or specification, the customer should provide relevant information such as GMP,‌FDA, etc., to ensure that the design meets the relevant regulatory requirements). In addition, if the customer has other specialrequirements, such as energy saving requirements, safety considerations, etc., these special requirements need to be fully considered and realized in the design stage.

  The modifications toenclosed cleanroom applications mainly include comprehensive evaluation of the cleanroom structure, purification and air conditioning equipment, and indoor environment, and corresponding modifications and optimization. First of all, a comprehensive inspection of all equipment in the cleanroom is required to ensure that the equipment can operate normally; at the same time, various parameters of the clean area are tested (including cleanliness, temperature and humidity,air velocity, etc.) to determine whether the indoor environment meets the standards. Combined with the equipment status and indoor parameters, determine whether there is a need for modification and the scope of modification. The transformation mainly considers the requirements of process equipment and environmental conditions. By reasonably transforming the existing air purification system, the indoor air quality can reach the predetermined cleanliness standard, reduce the indoor dust concentration, and timely discharge the pollution generated indoors, so as to improve the application effect of the closed clean room and ensure the quality and reliability of the product.

  Clean rooms are divided into different grades according to the maximum allowable concentration of suspended particles of different particle sizes in thecleanroom air, and nine different levels of clean rooms such as cleanliness level 1-9 are specified in the ISO.

  In addition, the grade standard of GMP ondrug production clean room is divided into four grades: A, B, C and D, and each grade is also divided according to the maximum allowable concentration of suspended particles of different sizes in the indoor air under different states.
