If the suction of the range hood is too large, it may lead to many problems, including loud noise, large electricity consumption and even affect the cooking effect of food. The following are some solutions:

1. Adjust the air volume of the range hood. Most range hoods have multi-gear wind speed control, which can be adjusted as needed to reduce suction. It is suggested that commercial kitchens with large ventilation area or using high-performance range hoods can choose range hoods with step-by-step adjustable air volume function.

2. Use anti-blowback device. When the difference between the internal pressure at the suction port of the range hood and the indoor pressure is too large, it will lead to back blowing, and it is difficult for the smoke to be exhausted and ventilated. At this time, anti-back blowing devices can be used, such as installing air brakes and tail spraying devices.

3. replace the range hood pipe. Some old or used range hoods may need to be replaced with pipes to achieve proper suction, improve efficiency and save energy. It is recommended to use stainless steel air duct, and stainless steel composite air duct with insulation layer can be considered for kitchen environment with high exhaust or complex environmental conditions.

4. activate other ventilation equipment such as window opening to cooperate with the range hood. In order to prevent the suction of the range hood from being too great, other ventilation equipment can be used to cooperate with the range hood in the kitchen, such as opening windows or doors and using ventilation equipment such as the exhaust fan of the water heater to reduce the working pressure of the range hood, thus ensuring good ventilation effect.

in a word, the suction of the cooking range hood is too large, which needs different treatment according to different situations. Modern restaurants need to consider many aspects such as fume purification efficiency, energy consumption and environmental protection, so you may wish to ask professional designers or installation engineers to help you analyze and solve this problem.
