What is the problem with the low air volume of the range hood? What should I do if the air volume of the range hood is low?

Range hoods are a type of kitchen appliance that we often see in our lives, but many people encounter the problem of low air volume when using range hoods. So what is the problem with low air volume of range hoods? What should we do if the air volume of range hoods is low? The following editor will explain them one by one, hoping to help you.

What is the problem of low air volume of range hood?

1. The air volume of the range hood is related to the motor power and air volume of the range hood itself. If the rated power is small and the air volume is small, it will definitely feel small. After the range hood has been used for a period of time, the air volume of the range hood will become smaller due to the blockage of internal oil stains. At this time, you need to find a professional to clean the range hood.

2. The exhaust duct is not exhausting smoothly. A high-power range hood has a large air volume in the store, but a small air volume after installation at home. It may be that the flue is blocked, or there is a leak in the flue exhaust pipe, the flue check valve is of poor quality, and the baffle fails to open completely, resulting in poor exhaust.

3. When the range hood is working, if the doors and windows are closed, the air circulation in the kitchen will be poor, forming negative pressure and causing the exhaust volume of the range hood to decrease. It is recommended to open the windows to circulate air and replenish the air pressure when the range hood is working. However, the windows should not be opened too wide, which will interfere with the air circulation of the range hood and even cause the wind from the windows to blow away the oil smoke. Just open a small gap.

What to do if the range hood has low air volume

1. When using the range hood, keep the kitchen properly ventilated and be careful not to open the window too wide, otherwise it will affect the smoke exhaust effect. It also depends on the size of the kitchen. A kitchen that is too large will also affect the smoke removal effect.

2. If the range hood has not been cleaned for a long time, the turbine inside will be clogged with oil and the suction power will also decrease. Then you need to find a professional to thoroughly clean the range hood.

After excluding the above points, if the suction power of the range hood is still weak, it means that there is a problem with the range hood itself, and you need to contact the manufacturer's after-sales service or an electrical appliance repair department to check it out.

How to solve the problem of range hood blowing air

Installing a check valve at the air outlet of the range hood that does not rely on the wind power of the range hood to open, closes tightly, and opens properly can eliminate oil fume backflow and smoke exhaust. On Taobao, you can search for four "electric oil fume check valves", all of which use electromagnets or motors to open the check valves, and they can effectively eliminate oil fume backflow.
