Comparison between efficient air supply outlet and FFU cleanliness
Comparison between efficient air supply outlet and FFU cleanlinessA high-efficiency air supply outlet with an air volume of 1,500 was used for this project renovation. After the installation was completed, it was tested through special testing equipment. The high-efficiency air supply outlet supplied by our company reached level 100 cleanliness at the air outlet position.What is the difference between high-efficiency air supply vents and FFU? People who are engaged in the purification industry should be familiar with high-efficiency air supply vents. It is one of the most commonly used equipment at the end of the clean room. As FFU and FFU, it is quite different. So what are the differences between them? 1. The high-efficiency air supply outlet and FFU fan filter unit are used for newly built thousand-level, ten-thousand-level, and ten-level Terminal air filtration equipment for class 10,000 and all levels of clean room purification projects, key equipment to meet purification requirements, can be widely used in purification air conditioning systems in medicine, health, electronics, chemical industry, and other industries. 2. Commonly used plates for the production of high-efficiency air supply outlets and FFU fan filter units include cold-rolled steel plates (A3 plates), galvanized plates, and stainless steel plates (SUS201, SUS304, SUS316, etc.). The thickness is generally 0.8~1.5mm. 3. Structure of high-efficiency air supply outlet and FFU fan filter unit: A. The high-efficiency air supply outlet is a non-powered device and needs to be equipped with an air duct. The four-piece set of high-efficiency air outlets includes: 1. High-efficiency air supply port static pressure box. 2. Flange. 3. High-efficiency filter. 4. Air outlet diffuser. B. The FFU fan filter unit is composed of an air supply box, a flange, an air deflector, a fan, and a high-efficiency filter. It is a purification equipment with a power device and can be used alone or connected to an air duct. Understand that FFU is structurally divided into integral type, split type, and filter bottom type. Each of the three methods has its advantages; but from a long-term development perspective, the split-type fan is more suitable for future development. It is not only installation Maintenance and maintenance are more convenient, and the usage rate of the product is greatly improved, making the product more energy-saving and environmentally friendly. According to the way of electricity consumption, it can be divided into AC motor FFU and DC motor FFU. Features of each series of FFU produced by our company: High-efficiency, low-noise turbofan: computer three-dimensional modeling and simulation analysis, higher efficiency and lower noise. Beautiful appearance and user-friendly design: stainless steel handles are installed for easy installation and transportation. The corners are rounded and there is no indentation or bending. Considerate and Convenient Design The machine body is designed with an installation pedal, making the machine body installation and maintenance more convenient. High-performance low-noise fan: It adopts an EBM fan imported from Germany, which has ultra-low noise, uniform wind pressure diffusion, uniform and stable air outlet speed, low power consumption, low operating cost, and a working life of more than 80,000 hours. Multiple safety protection: touch control panel, no mechanical key switch, single-key induction, safe and reliable, over-current, over-voltage, and over-heat protection. Lightweight and thin body: without a filter, the thickness of the body is 25cm and the weight is only 25 kg. It can also be used in places with low ceilings. FFU internal current balancing design: ensures that the FFU surface network speed uniformity deviation is less than ±10%. Flexible and diversified design: In addition to standard models, we can also produce non-standard products of different specifications according to customer needs. Such as changes in filter type, bulk material, etc. FFU's various optional accessories also determine the price of FFU: optional air inlet primary filter, air inlet pipe, remote control, differential pressure gauge, and other optional accessories. When selecting FFU, attention should be paid to the operational relationship between the FFU static pressure value and the pressure loss of the clean room system. Generally, the FFU manufacturing factory only installs the FFU with a high-efficiency filter, and then measures the air volume and power consumption data in an open space. The pressure loss of the FFU at this time is only about 100~150Pa (only the impedance of the HEPA high-efficiency filter), which is much lower than The actual pressure loss impedance value of a clean room is 170~220Pa. Therefore, although the measured air volume and power consumption data can reach the standard values, after the actual installation in the clean room, the impedance of the raised floor, cooling coil, air duct, pipeline, etc. will change. Increase, the performance of FFU is reduced and it cannot meet the requirements of a clean room. |
