Fan blade material: the general market is based on the aviation material technology to ensure that the fan blades of the integrity and stability, enhance the fan blade corrosion and oxidation resistance.
Motor: more types of motors, but generally speaking, the market industrial fan with reducer integrated machine is more, a little more secure, when the fan is rotating at high speeds, reducer can be automatically turned on to buffer the machine high-speed operation.
Inverter: the combination of inverter system is very important, the need for built-in security protection module, with a ground fault, over temperature and short circuit protection and other functions, can be an unexpected situation automatically cut off the output to increase security.
Plug-in: external plug-in, to ensure the strength and toughness is particularly important.
Fan blade length: fan blade on the market are generally 3.7 meters -7.3 meters, according to their own factory to choose.
Noise: ≤ 40 dB best, according to research, the noise range of the machine is a normal work can be guaranteed range, but also on the factory sound environment is more reasonable range.
