In the food and beverage industry, fumes and noise are often the main causes of complaints. Oily fumes not only affect the dining experience of customers, but can also pose a potential threat to the health of employees and customers. Noise problems can interfere with the lives of the surrounding residents. Recently, we have noticed that the noise generated by the fume purification equipment in the restaurant is getting louder and louder, causing disturbance to the surrounding residents. In order to solve this problem, we need to find out the cause and take action accordingly. 
1. The reason for the noise of the oil fume purifier is the aging of the equipment: after long-term use, some parts of the oil fume purifier may be aged or worn, resulting in more noise during operation. For example, a motor's bearings are worn or underlubricated, which can cause the motor to produce an unusual humming sound while it is running. In addition, the aging of the circuit board can also lead to the unstable operation of components such as power transformers, resulting in noise. Filter clogging: Impurities and grease in the oil smoke can easily clog the filter, causing the purifier to work poorly, resulting in greater noise. When the filter is clogged, the resistance of airflow through the filter increases, causing the motor to require more power to drive the fan. Failure to fix the equipment firmly may cause the equipment to vibrate or move during work, resulting in noise. In addition, poor pipe connections can also lead to unstable airflow, resulting in noise. 
2. Solutions to reduce the noise of the fume purifier Regularly maintain and maintain the fume purifier and check whether the various components of the equipment are working normally. For aging parts, such as motor bearings, circuit boards, etc., replace or repair them in time. Clean the filter regularly to avoid clogging and keep the equipment running smoothly. If there is a problem with the installation of the equipment, you can ask a professional to reinstall it to ensure the stability of the equipment and the reliability of the pipe connection. During the installation process, the horizontality and verticality of the equipment should be ensured to avoid vibration or movement of the equipment during the working process. 
When buying a new oil fume purifier, you can choose a low-noise device. Some brands have been able to offer low-noise fume purifiers that use advanced noise reduction technology and materials that are able to effectively reduce noise during operation. Reducing the noise of a fume purifier requires a number of aspects, including the maintenance of the equipment, the cleaning of the filters, the reinstallation of the equipment, and the selection of low-noise equipment. Only by taking comprehensive considerations and taking corresponding measures can we effectively solve the noise problem and create a quiet living environment for the surrounding residents.
