What are the differences between a clean shed and a clean room?

    The two are clean equipment, but they are essentially different. The clean area of the shed is regional clean, and the clean workshop is clean in all areas. The main differences between clean sheds and clean rooms are as follows

    1. Size and design: A clean room is usually larger than a clean shed, which is a relatively closed positive-pressure environment built in a dust-free workshop to protect specific items or experimental processes from contamination. A clean room is a specially designed building structure that can meet the requirements of cleanliness, temperature, pressure, airflow velocity, and airflow distribution within a specific range of needs.

     2. Filtration system: Clean rooms usually use more complex filtration systems, including air filters, air flow adjustment systems, etc., to ensure that the indoor air contains almost no particulate matter. Clean sheds generally use industrial aluminum profiles as the frame, with plexiglass or anti-static mesh curtains installed around and on the top, and FFU laminar air supply units.

    3. Materials and construction costs: Clean sheds generally use industrial aluminum profiles as frames, while clean rooms usually have more equipment and functions, such as stainless steel walls, special floors, air cleaning devices, humidity and temperature control systems, etc. There are purification equipment such as air showers and transfer windows. These equipment and functions will increase the construction cost. In general, the construction cost of a clean shed is 40%-60% of that of a dust-free workshop.

    4. Cleanliness requirements: The cleanliness of a clean shed is usually ISO level 7 or lower, which allows a certain amount of particulate matter to exist. The cleanliness requirements of clean rooms are determined according to the needs of different industries and application fields and can reach up to ISO level 1, which requires almost no particulate matter.

    5. Usage environment and comfort: The clean shed is quick to construct easy to disassemble and assemble, and is suitable for the protection of specific items or experimental processes that do not require high cleanliness. However, the internal space of the clean shed is relatively closed and lacks an independent air supply system. Using a large number of FFUs may result in excessive noise and stuffy heat. Clean rooms are slow to construct and costly but have independent air supply systems and higher comfort levels.

    In general, there are significant differences between clean sheds and clean rooms in size, design, filtration systems, construction costs, cleanliness requirements, and usage environments. They play an important role in different fields to ensure product quality and accuracy of experimental results.
