Denition of the supply/extraction grilles
To ensure the air in the rooms is puried correctly, rst dene the position of the inlets and outlets, considering that the renewal air inlets must be tted in
the main areas(living and room), while stale air must be extracted from utility rooms (kitchen and bathrooms).
The following fall into the category of service rooms: the kitchen, bathrooms, laundry room, closets; other rooms where sometimes you might provide
return grilles are large walk-in wardrobes and mezzanines where generally the phenomenon of air stratication occurs.
The following fall into the category of noble rooms: the living room, bedrooms and studies; in each of these rooms it is essential to have one or more inlets
for fresh air intake.
The supply inlets must be positioned according to the type of inlet that is used:
•
the AIRJET 50/l or 80/l diusers (DAIR50X and DAIR80X), due to their high induction diusion characteristics,
allow an even spread of air entering the room. This particular feature allows you to place the grille only at the
top of the vertical walls, e.g. above the door or in the most appropriate position to direct the airow in order
to have a comprehensive eect in the whole room.
•
the square grilles (GIVEX and GINOX) do not permit an air launch at the outlet of the grille itself and so their
position must be at the farthest point in such a way that the air ow from the outlet to the door in the direction
of extraction, aects the whole environment. The rectangular grilles can be installed at oor level or on the wall
at electric socket height or near the ceiling.
•
the square grille (GQIEX) or the valve (VIEX) do not permit an air launch at the outlet of the grille itself and so
their position must be at the farthest point in such a way that the air ow from the outlet to the door in the
direction of extraction, aects the whole environment. The grilles must be positioned on the wall near the
ceiling or on the ceiling.
The air must always be extracted from above by positioning one or more outlets in all the rooms with higher
humidity and pollutant levels.
The ELFOAir system uses the same grilles for extraction as for supply except for the AIRJET 50/l and 80/l diusers
that are replaced by AIRJET 50/A and 80/A suction grilles.
The grilles or valve (GIVEX, GINOX, GQIEX, VIEX) used in extraction must only be placed high up or on the ceiling.
Note: It is essential to make sure that there are no objects in front of the openings/grilles (furniture, wardrobes, etc.) that could interfere with the normal air
circulation in the rooms.
The supply air ow (extraction) must therefore be determined for each single room as follows:
The supply renewal rate (extraction) is calculated as the relationship between the total volume of the rooms where the air is supplied (extraction) and
ELFOFresh

’s rated air ow and this is multiplied by the volume of the room.
The number of openings/grilles to use for each room depends on the air ow of each room, bear in mind the maximum air ow allowed for each opening.
Note: It is good practice to make sure the rooms have a renewal air ow of at least 20 m³/h per person.
Note: If in one room there is a supply point and a return point (e.g. single kitchen-living room) it is necessary to make sure that you do not create a by-pass i.e.
that the air blown into the room is not immediately sucked away without aecting the environment. In this situation you should place the supply point low
down and extraction point high up on opposite walls in the room, or have the supply provided by AIRJET diusers and extraction from the same position.
