Calculating the Right Amount of Suction Power for a Kitchen Chimney

The more spacious the kitchen, the more suction you will need for the chimney. The rule of thumb is this: The kitchen chimney has to fill the kitchen ten times an hour.

To determine the required suction power of the chimney, we need to calculate the volume of the kitchen and multiply the volume of the kitchen by ten, because the chimney in your kitchen will refresh your kitchen ten times in an hour for which it has to be filled with air.

To calculate the size of the kitchen, you need to know the length, width, and height of your kitchen, which increase together. Finally, multiply the resulting volume by ten and you will get the desired chimney suction power in your kitchen.

Let us consider that the size of your kitchen for the moment is: The size of your kitchen is 4 mx 4 mx 2.5 m = 40 m³. Fresh air, equal to the volume of the kitchen, needs to be exchanged 10 times per hour, so 10 x 40 m³ = 400 m³ / h. So, your kitchen needs a chimney having at least 400 m³ / h suction power.
