What is a cooker hood?

A cooker hood is an electrical appliance designed to eliminate odours and fumes released when cooking food.

It therefore helps ensure a health environment, free from harmful substances, increasing well-being and significantly improving quality of life in the kitchen.

Galvamet supplies products to suit all types of kitchens, developed using cutting-edge technology with top suction performance and a careful focus on design and look.


How to choose the best hood

The following are the main points to consider when choosing a hood:

Type of installation

First and foremost, the choice of hood must fall to one designed for the installation required. Depending on where it is to be installed, there are four basic different types available:

  1. wall-mounted, when the hob lies against a straight wall
  2. island, when the hob has no surrounding walls
  3. corner, when the hob is situated in a corner of the kitchen at a diagonal
  4. built-in, when the hood is installed inside a wall unit positioned above the hob

Suction power

The second consideration must concern the size of the environment in which the hood is to be installed and the frequency with which it will be used. Suction power is expressed in m3/h, which represents the volume of air that the hood can suction up in an hour. For small kitchens, a hood with a performance of up to 400 m3/h will suffice, whilst medium or large kitchens really require a hood with performance starting from 500 m3/h.


In making the decision, it is also important to consider the hood size, ensuring that the model chosen is not too small with respect to the hob beneath.


The cooker hood is now without doubt a design feature in a kitchen and helps exalt the value and beauty of the environment in which it is installed. It is therefore essential to choose the look of the hood in such a way as to make for a final result that matches with your expectations. All Galvamet products are the purest possible combination of the very best, futuristic design for domestic suction combined with construction and technology concepts that are today unexplored.



Proper installation is essential to correct hood function; please contact a specialised centre to have the certainty that it will all work to the best of its capacity.

Full information is given on how to install correctly in the instruction manual included in all our packs.

Virtually all Galvamet hoods are prepared to operate both in filter version and suction version.

In the suction version, the air taken in by the hood is expelled outside. In this case, we recommend connecting the hood to the outlet hole in the wall or ceiling using a smooth tube within travelling as straight as possible. Twisted or very long routes may result in a drop in the appliance performance and noisier operation. In this version, there is no need to install active carbon filters in the hood.

In the filtering version, fumes are not expelled outside but rather returned to the environment once the odours have been eliminated by the active carbon filters. In this case, no tubes are required.

To guarantee higher performance and quieter operation, we recommend installing a suction hood.

Current safety legislation requires there to be a certain distance between the installation and the supports of containers on the hob. To avoid damaging the product and to protect personal safety, please always comply with the distance specified in the product instruction manual. 



Always unplug or disconnect the product from the electricity before carrying out any maintenance work.

The hood must be cleaned immediately after installation and the removal of the protective film in order to eliminate any glue residues, prints and other potential impurities.

The hood must be cleaned regularly and carefully, both inside and out.

Never allow dirt to accumulate on the interior or exterior surfaces of the hood.

Do not use acid or base products or abrasive sponges to clean the external frame. Clean the hood with a sponge dampened with warm water and a small quantity of neutral detergent (e.g. washing-up liquid) to eliminate any traces of fat that may have deposited on it. Then rinse with a damp cloth, carefully removing all detergent and taking care to follow the direction of the satin finish on steel surfaces. It is very important to dry thoroughly, even more so in areas where the water is particularly hard and may therefore leave scale deposits.

Pay careful attention to metal fat filters which are used to withhold the fat particles contained in the steam created while cooking. These filters must be washed at least once a month with hot water and detergent (they are dishwasher safe). The filters can discolour after a few washes. This is normal and does not mean they have to be replaced.


The fat withheld by the metal filters is very flammable. This makes it very important to clean them regularly, as instructed.

The active carbon filters, which seek to withhold the odours particles from cooking fumes, should not be washed; they should be replaced every 2-3 months depending on hood use.


Energy Classification

With the Regulation 65/2014 of the Commission of the European Parliament, has been introduced the new energy labeling, that must be applied to all the cooker hoods produced in the 28 Member States starting from 1st January 2015.

The label, which is the same for all manufacturers and Member States, shall include the following data:

Colored arrows: to differentiate the high-efficiency products from the low efficiency products: dark green to indicate a highly efficient product and red to indicate a lower efficient product

Annual energy consumption in kWh (4): annual energy consumption estimated for standard use

Fluid dynamics efficiency class (5): indicates the efficiency with which the hood sucks the fumes generated by cooking (A maximum - G minimum efficiency)

Lighting efficiency class (6): indicates the efficiency with which the hood lights the hob (based on the relationship between the average illumination and the nominal electric power of the lighting system) (A maximum - G minimum efficiency)

Filtering efficiency class (7): indicates the efficiency with which the hood filters the fat generated from cooking (A maximum - G minimum efficiency)

Noise level (8): indicates the maximum level of noise generated by the hood in standard use
