What determines the quality of a hood?
Besides its physical appearance, which is essential to its integration into a particular environment,
the efficiency of its suction, the level of silence offered and the mechanical and electrical safety of
the product are all fundamental aspects which should be taken into consideration when choosing
a quality product.
How to select the correct capacity
The necessary suction capacity usually depends on the size of the kitchen and on the cooking
method used. A single calculation can be used to identify the correct product capacity. Simply
multiply the volume of the room by 10 and this will give you the ideal capacity for that area.
For example, when fitting a hood in a kitchen measuring 3 x 4 m with a height of 2.7 m: (3 x 4
x 2,7) x 10 = 324
Therefore, any product with a maximum capacity of over 324 m3/h will be able to guarantee full
and efficient ventilation in the room.
Do not forget, however, to take your cooking habits into account:
For anyone who regularly prepares food quickly and has a small kitchen, the model should have
a capacity of up to 300/400 m3/h. For a family of three or four people with an average-sized
kitchen and whose cooking methods are varied, the model should have a capacity of 400/500
m3/h. For larger families and cooking enthusiasts, or where large groups gather in a roomy
kitchen to sample exotic recipes, the hood model should have a suction capacity of at least 600
m3/h.
Efficient cooking vapour suction also depends on the correct operation of the product. The hood
should be switched on at the first speed level as soon as you begin cooking and the suction speed
increased as necessary. Once you have finished cooking, set a lower speed level and leave the
hood operating for another 5 to 10 minutes.
Efficient and silent
All Elica hoods are designed and created with these two fundamental concepts in mind. The
constant research carried out by Elica led to the introduction of a new suction system, called
the Optimized Aspiration System, which provides optimum performance in terms of smoke and
vapour suction with a reduced noise level.
Performance
All product performance quoted in this catalogue is measured according to the most recent - and
most stringent - technical regulations.
CAPACITY / PRESSURE REGULATION IEC61591
The values (expressed in m/h) q uoted in this catalogue are listed in the technical specification
sheet corresponding to each product, under the following headings:
- IEC CAPACITY: The test is performed with sample ducting applied to the product.
- F.O. CAPACITY: Free Outlet: The test is performed directly at the hood outlet.
NOISE LEVEL - Regulations IEC60704-1; IEC60704-2-13

Choosing a model
All models are designed to work as an evacuation (Ducted) version (A), where the air sucked in is
expelled outside, or as a recirculation (Filtering) version (B), where the air sucked in is filtered by a
grease filter and an odour filter and then released as purified air back into the room.
The choice of which version to install depends entirely on your own requirements. There are,
however, some simple measures which should be borne in mind.
For the ducted version, the hood must be connected to the outside environment using special
ducting so that all the captured air may be safely expelled outside. For this configuration it is
important that the ducting has a sufficiently large diameter (120 mm or larger) and that it is not
too long or subjected to many bends. The above information is important in order to prevent load
losses, in other words reduced cubic metres of capacity, occurring due to aerodynamic resistance
in the duct.
For the filtering version, the hood is not connected to a duct because the air is purified using the
relevant active carbon filters and then released back into the room. For this configuration, it is
extremely important that the odour filters are subjected to regular maintenance and, if necessary,
replaced.
