4-68 series large flow centrifugal draft fan

working conditions

　　The 4-68 centrifugal fan can be used for both input and output gas. The gas delivered by the 4-68 fan should be mostly air not exceeding 80°C and other gases that are not easy to spontaneously combust, harmless to human body, and non-corrosive to steel materials. The gas should not contain viscous substances, and the dust and hard particles contained in it should not exceed 150mg/m3.

Application scenarios

　　It is used for building ventilation, ventilation and drying of materials, air purification and industrial waste gas treatment, industrial dust collectors, air purification and discharge of harmful working environments (paper production lines, electrolytic aluminum production lines, textile factories...). Blast of boilers and brick kilns, conveying of various gases, conveying of granules/powders/crumbs/fibrous materials, etc.

Fan structure

Fan Features

　　●In the case of meeting the pressure requirements, it can output a large gas flow and the noise is very low.
　　●The motor adopts the high-efficiency and energy-saving motor of the Chinese motor manufacturer (you can also install the user-required brand motor), with reliable quality and lower energy consumption
　　●V-belt drive can make your fan run at the most suitable speed. Installation is simple and requires no technical support.
　　●The airflow channel and impeller have been optimized for many times, which is more efficient and energy-saving than ordinary large-flow fans.
　　● Made of high-quality carbon steel, stainless steel or other metal materials can also be used according to user requirements.
　　●The impeller is annealed to eliminate the internal stress of the structure during welding, and to ensure that the impeller will not have creepage and cracks.
　　●After the production is completed, all of them have undergone the operation test and vibration value detection, and the operation is reliable.
　　●Easy to install, no need for technical support.
