Anonymous users2024-01-24Individuals are also equipped with exhaust fans with large air exchanges, and women cook rice every day, and their skin and hair are afraid of being very oily. It is an exhaust fan with integrated ceiling belt of Gefeng, and I feel that the exhaust volume is twice as large as the average, and the noise is small, which is quite practical.

Anonymous users2024-01-23It's not that the air change of the ceiling is large, but the factory produces ventilation fans, and I suggest that you have an integrated ventilation fan of about 300 yuan.
Experience is something that can be learned by looking more, asking more, touching and thinking more, rather than simply asking a few people to know. I don't think I knew much about this back then, and I had questions. But after a few years of hard work, I have made small achievements in this industry, so it is very easy to list a few good brands for you. >>>More
The power is related to the model and specification of the exhaust fan, the general household from more than ten watts to forty watts, the noise mainly depends on the quality of the motor, and the good exhaust fan motor is imported from Japan. Generally, no more than 1 kilowatt-hour of electricity is turned on a day.
This question actually depends on how you choose electrical appliances, generally speaking, manufacturers like to concentrate various functions into an electrical appliance, just like mobile phones, other mobile phone factories have functions, I also want to have, but in fact, what is good is a single function of the product, such as a camera, the camera is specially used to take pictures, the mobile phone and camera produced in the same period must be a more professional camera, but it is not that the mobile phone can not be used, the lighting ventilation fan is the same problem, The lighting and exhaust functions are integrated in a limited space, then the function of the lighting and exhaust fan will have an impact, which is a compromise solution, then the ventilation fan generally sacrifices the control of exhaust air volume and noise, and the heat dissipation and reflector of the lighting are bound to affect, but in terms of price, it is cheaper than buying two separately, and it will be more expensive than a single product, so this depends on how you choose, if it is recommended, as far as possible to separate the lighting and ventilation to choose, Moreover, the service life of lighting products is longer than that of ventilation fans, and when ventilation fans need to be cleaned, or when they are replaced with new ones, the integrated products are inconvenient and economical.
Of course, you can, there is an exhaust duct.
This question is mainly based on aesthetics. It depends on what the interior design scheme looks like. >>>More
