The axial fan has a good effect.
The treatment methods of fan noise are generally divided into the following types: >>>More
You belong to the public smoke shaft, you can consult the fan professional, you can choose a type.
Replace it with a low-noise cabinet centrifugal fan, with the same parameters, the noise is about 10 decibels lower than that of the axial fan, and the energy consumption is also lower.
Kitchen fan noise control method.
1.The noise control of the exhaust outlet of the fan generally adopts the method of installing the fan muffler, and the design noise reduction amount may be different according to the specific noise of the fan. In order to effectively reduce the air noise of the equipment and the regenerative noise caused by high-speed airflow, we install impedance composite mufflers at the smoke exhaust outlets. >>>More
Fan silencers can be installed, which are mainly used to reduce the aerodynamic noise of various fan tuyeres, air ducts and closed machine room air intakes.
