Product introduction: FFU is usually installed at the air supply end of the clean room. The FFU system has the characteristics of simple design and construction, flexible wind speed adjustment, and easy change of clean areas. Therefore, FFU has become one of the popular system forms of industrial clean rooms.
Product features: Integrated control of box structure, material, efficiency, noise, vibration, harmonics, power factor, bearing life, temperature rise, safety regulations, shaft current suppression, response time, etc. through the network system. To achieve the best operational results between the clean room and FFU equipment, thereby achieving the requirements of improving efficiency, safety, energy saving and cost reduction.
Technical environment: Compared with general clean room environmental requirements, automation and process equipment have special requirements for the clean environment. The first consideration is how to suppress and eliminate the large amount of dust generated when the automation equipment moves, and the second is how to prevent Contamination from the lower cleanliness level environment around it (the establishment of room pressure). In addition to clean environments, FFU installed in automation and process equipment also require special installation height (thin profile). Especially for warehouse automation FFU, it will be required to be installed on the side and fixed on the scaffolding, so the installation method needs to pay special attention to the strength and the convenience of disassembly and assembly during maintenance.
Fan: aluminum alloy material with integral lamination process. The wind speed is 0.25-0.45m/s, the windmill efficiency is more than 45% (@0.4m/s), and it can still provide sufficient cooling at the minimum air volume. The bearings of the motor require no maintenance, are precision, insulated and non-magnetic, and are low-friction type to avoid electric shock problems caused by shaft potential, resulting in abnormal vibration and noise. Bearings are designed to have an operating life of 1,000,000 hours at normal ambient temperatures.
Parameters: When FFU operates at a wind speed of 0.35m/s and a total static pressure (TSP) of 300Pa, the efficiency is greater than 50%.
