The suction of range hood is very important. If the suction is too small, the oil fume and oil vapor cannot be effectively sucked away, thus affecting the cleanliness of the kitchen. Here are several ways to improve the suction of catering range hoods:

1. Cleaning the range hood: If there is oil stain on the exhaust port and filter screen of the range hood, the suction will be blocked, so the range hood should be cleaned every day, especially the exhaust port and filter screen.

2. Replace the filter screen: if the range hood is used for too long, the filter screen will be covered with oil, which will affect the suction. At this time, it is necessary to replace the new filter.

3. Change the exhaust pipe: Sometimes the exhaust pipe of the range hood is too long or bent, which will also lead to insufficient suction. The exhaust pipe can be shortened or modified.

4. Increase the fan power: If the above methods are ineffective, you can also consider replacing the fan or increasing the fan power, which can improve the suction of the range hood.

In a word, to improve the suction of catering range hood, we need to start from many angles, find out the reasons and take corresponding measures to ensure good oil fume emission effect.
