FFU： The core part of a clean room
As a closed structure that provides a highly clean environment, clean work booths are widely used in fields such as electronic manufacturing, biomedicine, and laboratories. However, achieving cleanliness and uniform airflow inside the clean booth cannot be achieved without the contribution of FFU.
First, FFU’s air supply and filtering are crucial for protecting a clean environment. With its built-in fan and filter, FFU can draw in outside air, filter it, and remove tiny particles, bacteria, viruses, and other pollutants. This cleaning process makes sure the air inside the clean booth is good quality, giving workers a reliable and clean place to work.
Second, the uniformity of FFU’s airflow is very important for the operation of the clean booth. The airflow generated by FFU can be evenly distributed inside the clean booth, covering the entire work area. This even airflow distribution ensures consistent cleanliness, preventing situations where there are local pollution or differences in cleanliness inside the clean booth.
Also, FFU has adjustable airflow and speed controls. You can change the airflow and wind speed as needed. This flexibility helps the clean booth meet different cleanliness requirements and situations. For example, when higher cleanliness is needed for some tasks, you can increase FFU’s airflow and wind speed to provide more clean air.
FFU and the clean booth are closely connected. As a key part of the clean booth, FFU protects the clean environment by cleaning the air, providing clean air, and keeping the airflow even. During the design and installation of the clean booth, the selection and layout of FFU require detailed planning and consideration，to make sure the clean booth can meet the expected cleanliness requirements.
In practical applications, the performance and maintenance of FFU also need attention. Regularly replacing filters, cleaning equipment, and performing timely maintenance can ensure the normal operation and lasting performance of FFU. At the same time, a reasonable layout and number of installed FFU can ensure that the entire clean booth is fully covered with clean air.
The Cleanliness class of Clean Booths
The class of clean booths refers to the degree of cleanliness of the air inside, typically classified as Class 100, Class 1000, and Class 10000.
A Class 100 clean booth corresponds to the cleanliness level of ISO 14644-1 Standard Class 1, representing the highest level. Its cleanliness requirements are extremely high, with no more than 1,000 particles larger than 0.1 micrometers in diameter per cubic meter of air inside. This type of clean booth is commonly used for manufacturing high-precision, high-purity products such as semiconductor chips and optical components. In a Class 100 clean booth, high-efficiency filters, air showers, and other equipment are required to ensure the highest level of air cleanliness. Additionally, staff need to wear special cleanroom suits to prevent the introduction of external contaminants.
A Class 1000 clean booth corresponds to the cleanliness level of ISO 14644-1 Standard Class 2. The number of particles larger than 0.1 micrometers in diameter does not exceed 10,000 particles per cubic meter of air inside. Class 1000 clean booths are typically used in the production of semiconductors, electronics, pharmaceuticals, and other industries.
A Class 10000 clean booth falls within the cleanliness levels of ISO 14644-1 Standards Classes 3 to 6. The number of particles larger than 0.1 micrometers in diameter does not exceed 100,000 particles per cubic meter of air inside. Class 10000 clean booths are commonly used in the production of food, cosmetics, and other industries. In this type of clean booth, primary, secondary, and high-efficiency filters are required. Regular cleanliness testing and maintenance are also necessary to ensure that the cleanliness standards are met.
Beyond differences in cleanliness levels, various types of clean booths also exhibit differences in design and construction. For instance, Class 100 clean booths require a fully enclosed structure to prevent external air from entering. In contrast, Class 1000 and Class 10000 clean booths can adopt a semi-enclosed structure to facilitate the movement of personnel and materials. Additionally, different types of clean booths need to consider internal environmental factors such as temperature, humidity, and pressure to ensure optimal production environments and product quality.
How to Determine the Number of FFUs in a Modular Cleanroom Booth?
In a modular clean work booth, an important piece of equipment is the FFU (Fan Filter Unit). It comes with its own power supply and can draw in outdoor air, purify it, and then blow it into the room. The number of FFUs is related to the purification capacity of the clean work booth. The number of FFUs needs to be determined through calculation, rather than being increased or decreased at will. Adding too many will increase costs, while reducing them will fail to meet the specified cleanliness level. So, how do we determine the number of FFUs needed for a dust-free clean room booth?
To determine the number of FFUs in a cleanroom, we only need to know three values: the air change rate, the volume of the cleanroom, and the air volume of the FFU. The specific calculation formula is: N = A * J / K (where A is the air change rate, J is the volume of the cleanroom, K is the air volume of the FFU, and N is the number of FFUs required).
air change rate
What determines the air change rate? To determine the specific air change rate, we need to choose the clean booth class and then identify the corresponding number of air changes per hour based on that class. A higher air change rate indicates that more airflow is required to maintain the air quality in the clean booth. Below is a commonly used reference standard:
| Class | Air Changes Rate per Hour | Commonly Selected Value |
| Class 100 | ≥200 | Generally 230 |
| Class 1000 | >50 to <100 | Generally 70 |
| Class 10000 | 25-30 | — |
| Class 100000 | 15-20 | — |
| Class 1000000 | 12-15 | — |
The volume of clean booth
Not only does the area of the cleanroom affect the number of FFUs (Fan Filter Units), but the height is also important. Both are fundamental for calculating the required air volume. According to the relevant specifications for prefabricated clean booths, the prescribed number of air changes applies to clean booths with a height of less than 4 meters. If the height is higher, additional measures such as increasing the number of air changes may be needed to achieve the desired cleanliness class.
the air volume of FFU
The air volume of an FFU (Fan Filter Unit) depends on its model and specifications. Here are some common FFU airflows and their characteristics:
Rated Air Volume Standards:
- 1000-type FFU: Its rated air volume is usually 1000 cubic meters per hour (m³/h). This type of FFU is suitable for air filtration in smaller spaces, such as clean benches and small clean rooms.
- 2000-type FFU: Its rated air volume is generally 2000 cubic meters per hour (m³/h). It is used for air filtration in medium-sized spaces, often found in cleanrooms, biosafety cabinets, and other places that require high air cleanliness.
- 3000-type and 5000-type FFU: These have air volumes of 3000 cubic meters per hour and 5000 cubic meters per hour, respectively. They are suitable for large cleanrooms, industrial purification plants, and other settings.
The air volume of an FFU directly affects its air filtration effectiveness and the cleanliness of the clean booth. Generally speaking, the larger the air volume, the better the filtration effect and the higher the cleanliness. In practical applications, selecting the appropriate air volume for an FFU requires comprehensive consideration of factors such as the specific needs of the clean work booth, the cleanliness level required, work requirements, and equipment layout.
