How many cubic meters of suction power is the national standard for range hoods?

National regulations, the hood air volume indicator value must be greater than or equal to 7 cubic meters / minute.

Hood air volume is a very important indicator, air volume refers to the static pressure is zero when the hood air volume per unit of time. The greater the value of the air volume, the greater the ability of the hood to absorb and exhaust fumes. So in the selection of range hoods, when other indicators are good, as far as possible to select a larger value of the air volume of the range hood.

The national regulations, the hood's air flow index value must be greater than or equal to 7 cubic meters / minute. You can get the airflow value by multiplying it by 8, 10 or 12, depending on the volume of the room.

Buying a range hood must look at a few data indicators

1, compared to the air volume, the wind pressure is a people should pay more attention to the factor: the greater the value of the wind pressure, it means that the range hood is more resistant to wind. Nowadays, most of the small areas of all households in the exhaust pipe, are connected to the public **** flue, the need for greater wind pressure in order to ensure that the smoke will be discharged, and to prevent the fumes back up. So if the user's home hood wind pressure is not large enough, the public **** flue smoke will be easy to invade.

2, direct suction range hoods do not have to be worse than the side suction of the net effect of smoke, direct suction range hoods using filters to separate the smoke, reducing the smoke on the wind blade and the erosion of the motor, and direct suction range hoods are more technically mature, the noise control is better. Users should pick according to their own needs, rather than just fetishize side suction range hoods!
