- Kitchens: ALIZÉ AUTO and ALIZÉ AUTO TEMPO dual flowrate vents provide a predetermined (“trickle”) extraction rate at a pressure head of between 50 and 160Pa and a boost extraction rate turned on and (on the ALIZE AUTO vent) off by the user.
ALIZÉ AUTO TEMPO vents come in three models for each flowrate:
ALIZÉ AUTO TEMPO cord: activation by pull cord
ALIZÉ AUTO TEMPO elec: activation by pushbutton, 230V power supply
ALIZÉ AUTO TEMPO battery: activation by pushbutton, 3 x 1.5V battery operated
- Bathrooms and WCs: the ALIZÉ AUTO single flowrate vent provides a predetermined extraction rate at a pressure head of between 50 and 160Pa.
The ALIZÉ AUTO single flowrate vent provides a predetermined extraction rate at a pressure head of between 50 and 160Pa.
Whichever self-regulating vent you choose, all models can be wall or ceiling mounted using the following methods:
Wall mounting: the vents can be fitted straight onto a Ø125mm duct or via a Ø125mm adapter fitted beforehand to the duct. The lip seal holds the vent in place and keeps it leak-tight.
To fit the ALIZÉ 120 and 150m³/h models onto a Ø99 adapter, use the relevant shim (code 1941).
Ceiling mounting: the vents can be fitted onto either a 3-claw drywall adapter or a Ø125mm through-slab adapter (Ø125/80mm for bathroom and WC vents).
ALIZÉ AUTO TEMPO
Wall mounting: the vents can be fitted directly onto a Ø125mm duct or via a Ø125mm wall seal adapter. The lip seal holds the vent in place and keeps it leak-tight.
Ceiling mounting, the vents can be fitted onto either a 3-claw drywall adapter or a Ø125mm through-slab adapter (Ø125/80mm for bathroom and WC vents).
The system must be sized to comply with the directive of 24th March, 1982 and with building regulation DTU 68.3.
Directives of 24th March, 1982 and 28th October, 1983:
These directives interpret the practical application of Article R.111.9 of the French construction and housing code, which in turn specifies the inlet and outlet flow rates that must be implemented to ensure sufficient air renewal in premises. The air renewal may be natural or forced.
Among the directive’s stipulations are high- and low-speed extraction rates in service rooms.
This document defines specific requirements for the implementation of ventilation installations.
As regards controlled mechanical ventilation (self-regulating and combustion gas types), the building regulation reads as follows :
- The air inlets taken as a whole are characterized by their flow rate at a pressure head of 20Pa (the M modulus)
- The minimum inlet airflow per main room is 22m³/h at 20Pa
- The air circulation flows from the main rooms toward the service rooms via the passages or corridors.
- Where timed vents are used, expansion must be accounted for.
The sizing of air inlets in a given dwelling, after taking the permeability of the building envelope into account, must produce the maximum extraction rate at a pressure head not exceeding 20 Pascals.
If ∆P = 20 Pa S ≥ Qm - Qf
where S = air inlet modulus sum
QM = maximum air extraction rate from dwelling
Qf = air leakage rate of the whole building envelope at 20 Pa shown in the table below.

- Directive of 30th June, 1999
This document defines the acoustic limits (acoustic insulation between premises or from outdoor noise DnT,A; acoustic pressure level Lp, acoustic power level, etc.).
The directive’s provisions apply to any residential building that has been the subject of an application for planning permission or of a declaration of works concerning the addition of storeys or other extensions to old residential buildings.
- Directive of 27th November, 2012
This document defines the implementation of compulsory anti-noise measures in operations involving at least ten dwellings.The directive’s provisions apply to residential buildings that have been the subject of an application for planning permission on or after 1st January, 2013.
Acoustic solution examples:
This document, published by the Building Scientific and Technological Centre (CSTB), is a design guide intended to facilitate the choice of equipment in a residential building in the aim of achieving compliance with the French New Acoustic Regulations without complicated calculations.
The examples in this document are non-compulsory suggestions for complying with Acoustic Regulations.
General solutions are given, calculated to result in conformity in all cases. They can be further optimized by other means tailored to each specific case.
The acoustic quality of products or systems is assessed on an ascending scale of performance from class ESA1 to class ESA6. The threshold for class ESA4 is set such that the performance of the corresponding products just meets the minimum requirements defined in the directives of 30th June, 1999 (acoustic regulations).
