How is the oil exhaust fan installed, and why can t the oil fumes in my kitchen be discharged

Look at what style of range hood you have, the manufacturer should come to install the ridge, our household is an integrated stove, do not need to be installed, directly integrated under the smoke of the bucket, and the smoke is also very clean Tongye mill, recommended Meida integrated stove.

You first look at whether the fan blades of the oil exhaust fan are rotating forward or reversed, and then see if the shutter or filter screen is blocked.

Whether you're using it in the countryside or in the city, when you buy a range hood, you have a pipe that you connect and you connect to the outside or put it in the smoke extractor.

It's the problem with your range hood brand.
