Choose your cooker

When you have to choose a cooker hood for your kitchen, apart from the way it looks, the air delivery is the most important component for your choice. The air delivery is the quantity of air that your appliance is taking each hour (m³/h).

The best way to calculate this is given as follows: surface of the kitchen x height from the floor to the ceiling x10, where 10 is a coefficient representing the number of air-exchanges that the cooker hood must do each hour to assure a correct ventilation.

Example:

(A) 4,3 m x (B) 3,8 m x (H) 2,7 m x 10 = 441 m³/h

So your hood, in order to assure a good air exchange, must have a suction capacity of 441 m³/h.

Version

Most of the models can be used in the 2 versions: suction use and filtering use. The suction hood use must extract air with grease, fumes and vapours from the inside environment and then must expel them outside. A filtering hood purifies the air with grease, fumes and vapours by means of carbon filters and then emits the purified air into the same environment. When it is not possible to use the hood in the suction use, then it is possible to make the hood filtering with a filtering kit composed of deflector and carbon filter. We recommend to always take care of the national valid norms.

Distances

The design cooker hoods must be installed at a minimum distance of 500 mm from the electric hobs and 650 mm from the gas hobs. They are conceived to be connected to a pipe with a diameter of 150 mm, anyway in front of possible special needs we supply them with a reducer that allows also to use connection to pipe with diameter of 120 mm. As a principle you can consider that the air delivery of the hood decreases with the length of the pipe, or with the number of the curves, or with the reduction of the pipe section. We strongly advice to keep the length of the pipe as short as possible, to avoid installation with many curves and to use pipes with 150 mm diameter.

Grease filters

The grease filters are made by a metallic frame having as average 10 layers of alunets which are allowing to capture in a very good way the grease from the cooking vapours. The grease filters must be kept clean with periodical washing operations both handmade or in the dishwasher.
