Airlite highly insulated natural louvred ventilator

Airlite is a natural louvred ventilator suitable for natural day to day and smoke control ventilation. It  conforms to EN 12101-2 and is CE marked. It can provide inlet and extract ventilation as well as the entry of natural daylight for most kinds of industrial and commercial buildings. It provides exceptionally high insulation and low air leakage as well as excellent aerodynamic and acoustic properties. It is suited for either façade or roof applications.

Product information

Features and benefits

Energy efficient - Airlite has been designed with the Energy Performance in Buildings Directive in mind, providing exceptionally high insulation and low air leakage.

High aerodynamic, thermal and acoustic performance - Airlite is aerodynamically efficient. It is highly insulated and is exceptionally air tight. It also provides a high degree of sound insulation.

Unique optional movable wind baffle – A wind baffle is installed to overcome side wind effects. This closes when the ventilator closes and so is invisible from the outside when the ventilator is closed, thereby enhancing its appearance.

Wide range of applications - Airlite is classed as a dual purpose ventilator, providing both day to day and smoke control ventilation. Airlite can also be installed in the vertical either for low level air inlet or for high level extract.

It allows the entry of natural daylight through its polycarbonate blades. There are pneumatic or electric controls and a wide range of accessories and finishes.

Easy to install - Airlite is delivered fully assembled to site and may be installed at any angle from the horizontal to the vertical. It has a wide range of base profiles to suit all sheeting, curb or glazing applications. A variable flanged variant is available for vertical installation into curtain walling, glazing or prepared openings.

Durable - Airlite is manufactured from tough, corrosion resistant aluminium alloy, with stainless steel fixings.

Certified performance - Airlite has been exhaustively tested and certified to EN 12101-2: 2003 in accredited third party test laboratories and is CE marked.

Quality of manufacture - Airlite is manufactured under strict quality control to ISO 9001. Each unit is given a functional test before despatch.

Options

Description

Clear opening natural louvred ventilator. Dual purpose, for highly efficient natural ventilation and smoke control, and suited either for extraction or inlet. Tested to and in compliance with EN 12101-2 and CE marked. Made from tough, corrosion resistant aluminium alloy.

Dimensions / size range

The ventilator is available in mm increments, from 500mm throat width to 2000mm throat width. It is available in 7 sizes from 1200mm to 3000mm throat length.

Louvre Options

Depending on the application, louvres made from:

  • 16 mm clear 7 layer multiwall (light transmitting) polycarbonate
  • 16 mm opaque 7 layer multiwall (light transmitting) polycarbonate
  • 16 mm grey 7 layer multiwall (non-light transmitting) polycarbonate

Double seals on the base and on the louvre are used throughout the range, which reduce air leakage when closed.

An optional moveable wind baffle which disappears when the ventilator is closed helps the ventilator to be aerodynamically efficient.

Base Options

  • Double skin insulated aluminium

Colours/ finishes options

  • Mill finish, standard
  • Painted to a RAL colour

Fixing options

  • Fixing flange for curb
  • Fixing flange for glazing
  • Curtain walling
  • Fixing flange for roof sheeting

Controls options

  • Electric (24V DC)
  • Pneumatic - either double action locking mechanisms or failsafe open.

If used as either an electric or a pneumatic smoke ventilator, activation is either by local thermal fuse which opens the unit at a pre-selected temperature, or by responding to an external release signal.

Other options/Accessories

  • Bird, insect, burglar and safety guards
  • Moveable wind baffle
