What is the difference between FFU and high-efficiency air supply vents in the purification workshop?

FFU is a purification equipment that integrates the functions of a fan, filter, and air outlet. It uses a fan to generate airflow removes particles in the air through a built-in high-efficiency filter, and then sends clean air evenly into the workshop. FFU has a compact design and flexible installation, suitable for various workshop sizes and layouts. It operates silently, has adjustable speed, and features low energy consumption and easy maintenance.

In contrast, high-efficiency air vents are components installed in a workshop's positive pressure air supply system. It delivers clean air evenly into the workshop through a centralized air supply. High-efficiency air supply vents can be adjusted to the size and needs of the workshop to ensure air circulation and cleanliness. High-efficiency filters are usually used to filter the air, and the air supply volume and wind speed are adjusted to adapt to the needs of the workshop. The air volume of high-efficiency air supply vents has different levels such as 500, 1000, 1500, 2000, etc. It is mainly used in terminal filtration of air purification systems in clean rooms, dust-free workshops, purification workshops, laboratories, etc. in various industries.

High-efficiency air supply inlets and FFU fan filter units are some of the commonly used air supply and air filtration devices at the end of clean rooms. They have both similarities and some differences. The following is the specific comparison between them.

1. Boxes are made of various materials, the common ones are cold-rolled steel plate (A3 plate), galvanized plate, and stainless steel plate (SUS201, SUS304, SUS316, etc.). The thickness of the cabinet is generally between 0.7 and 1.5 mm. The specific material and thickness can be customized according to customer needs, but the standard thickness of 1.0 mm is usually used;

2. Both types of equipment are suitable for clean rooms of Class 1,000, Class 10,000, and Class 100,000. They are key equipment to achieve final air filtration requirements in purification projects. It should be noted that the fan filter unit is suitable for clean rooms of Class 100 and Class 10, while the air supply outlet is usually not used for clean rooms of these classes. Whether it is a fan filter unit or a high-efficiency air supply outlet, they are widely used in purification air conditioning systems in medicine, health, electronics, chemical, and other industries;

3. The construction of these two devices is quite different. FFU is a purification and filtration equipment with a power device, which can be used alone or connected to an air duct. It consists of an air supply box, a flange, an air guide plate, a fan, and a high-efficiency filter. The air supply outlet is the terminal equipment of the centralized air supply method. It does not have a power device and needs to be equipped with an air duct. 4-piece set includes static pressure box, flange, high-efficiency filter, and air outlet diffuser;

4. The difference between FFU and high-efficiency air supply vents also lies in the installation method and air supply method. The FFU is usually mounted on the ceiling or wall of the workshop and can be adjusted and moved as needed. It directly supplies air to the workshop and can provide local purification solutions for the purification workshop. High-efficiency air supply vents are installed in the air supply system, which requires more space and layout planning. It delivers clean air into the workshop through a centralized air supply and is suitable for purification workshops that have strict requirements on air quality.

Through the above comparison, we can see the similarities and differences between the FFU fan filter unit and the high-efficiency air supply outlet. In the purification workshop, FFU and high-efficiency air supply vents play an important role in providing clean air. Depending on the size and needs of the workshop, appropriate equipment can be selected to achieve clean air goals. FFU has the advantages of flexibility and easy installation, while high-efficiency air supply vents have larger air supply distances and air volumes. After comprehensively considering the conditions and needs of the workshop, choosing the right equipment is the key to ensuring the effectiveness of the purification workshop. Zhongjing Purification specializes in the production of FFU fan filter units. The maximum air supply volume can reach 0.45m/s+20%. It is made of environmentally friendly galvanized sheet material, which is corrosion-resistant and not easy to rust. The box is designed with golden ratio points. The appearance is beautiful and elegant. We use high-quality special centrifugal fans, which have significant energy-saving effects and ultra-low noise. The air pressure is evenly spread, the outlet wind speed is uniform and stable, the operating cost is low, and the working life is more than 50,000 hours. It is widely used in medicine, electronics, Food factories, and other industries.
