CF produced by the factory muffler series type fan is used to control fan on the environment caused by the aerodynamic noise of the muffler. For various types of centrifugal and axial fan into and out of the silencer duct used.
Fan is a versatile machinery and equipment, using a wide range, power, mining, machinery, metallurgy, chemical and other industries are inseparable from the production of wind turbines. Fan noise generated during operation often affect the health of workers and interference ring
The curse of the environment. Especially the living area adjacent to the fan, the inlet and outlet of the radiated aerodynamic noise, pollution of the environment is a major factor in the formation of pollution, China's industrial sector in recent years, noise pollution control
One of the main targets of dye,
Industrial fans, is a continuous operation of the equipment. International Organization for Standardization (ISO) requirements for such equipment noise standards for the ≤ 90 decibels, of the same with this new standard, which is the industry standard noise based on business continuity
However, do not use muffler measures in case of import and export fan noise emitted to the environment up to 110 for a 120 dB, far exceeding the standard requirements.
