Combination ventilator sets for background venting and heat producing appliances.

Individual ventilation sets can supply up to a maximum appliance rated input of 28.7 kW (98,000 Btu/h) and are an ideal solution for refurbishment, remedial work and new build.

Aero wall ventilators fully comply with all Gas Board and Building Regulations requirements.

They are aesthetically pleasing and are a simple to install modular system, balanced for both good airflow and acoustic properties, which have been independently tested by BRE.

Combination ventilator sets offer a superior reduction of draughts and light, compared with basic through-wall ventilation.

How to Order

  • The size and number of anti draught ventilator products required, will be dictated by the requirements of the particular heating appliance, it is strongly recommended that advice is sought from the manufacturer.
  • State the correct anti-draught ventilator for the heating appliances to be vented or background ventilation required
  • State the required colour of extrnal cowl and/or grille

Installation Advice

Through the wall ventilators provide passive ventilation through external walls into habitable rooms.

It is important to differentiate between a ventilator which is required to provide general background ventilation and one which provides air into a room which contains a heat producing appliance, such as a central heating boiler or gas fire.

If only general background ventilation is required, then product selection is less critical.

A habitable room requires a free airflow of 8000mm² in order to comply with Building Regulations.

This can be provided by using two Timloc airbricks complete with cavity sleeves and internal louvred or hit and miss grilles. Alternatively, any one of the anti draught ventilator products can be used

If the room contains a heat producing appliance, the provision of constant and reliable ventilation is vitally important.

The anti draught ventilator products are strongly recommended for this application, as they fully comply with legislation governing gas and heating appliances.

The size and number of anti draught ventilator products required, will be dictated by the requirements of the particular heating appliance, it is strongly recommended that advice is sought from the manufacturer.


General recommendations for the specification and use of through the wall ventilation are:

  • Always check that the appropriate size and number of through the wall ventilators are used to suit the application
  • Never just fit an airbrick. A cavity sleeve must always be fitted to the back of the airbrick to ensure that the air is transmitted effectively through the wall and into the room
  • Hit and miss grilles may only be used for general background ventilation, they must never be used to ventilate any kind of gas or heating appliance
  • Ventilators used to provide air for gas or heating appliances must be permanently open, there must be no facility to block or close the ventilator. Also, they must not contain any kind of fine mesh or insect screen
  • Through the wall ventilators should always be fitted well above the external ground level, so as to ensure that rain and snow water cannot enter the ventilator
  • It is recommended that a section of horizontal cavity tray is installed directly above the through the wall ventilator, so as to prevent water from tracking across the cavity sleeve from the outer leaf to the inside of the building
  • In order to help reduce the effect of draughts, it is worth considering positioning the through the wall ventilator close to any heating appliance, rather than at the opposite side of the room, Positioning the ventilator at a higher level, rather than close to the floor will also be of assistance
