  • Unit length: 600 mm to 2500 mm (in mm increments)

Installation options

Fixing into glass is facilitated by the fact that there are many different sizes available.

Lightweight components reduce installation costs.


Thermally broken as standard.

Different flange types between 24 mm and 46 mm available.


The flap of the Firelight 3 ventilator is equipped either with insulated aluminium panels or different kinds of polycarbonate multi-wall sheets.

The units have been subjected to a wide range of tests, e.g. for wind load, snow load, impact resistance, resistance to rain, acoustic characteristics, and many others.

The following flap variants are available:

  • Single or insulating glass with an infill thickness of from 10 mm to 50 mm – triple insulating glass is also available
  • 32 mm thick double-skin aluminium panel – very durable polyurethane (PUR) panel infill with a density of 35 kg/m² – Lambda value 0.025 W/(mK)
  • Polycarbonate multi-skin sheet – thickness depending on the requirements
    Colour: transparent or opaque

It is also possible to use a customer-specific flap infill up to 50 mm thick.


The Firelight 3 is opened either electrically, pneumatically or manually by one or more actuators.

The following drives are available:

  • 24 V DC electric linear actuators
  • 24 V DC electric chain drive actuators
  • 230 V AC electric actuators
  • Double action pneumatic cylinders
  • Manual controls

Thermal release (for pneumatic cylinders)

A thermal ventilation valve with a connected gas bottle and a thermo bulb ensures automatic release in the case of fire.

Different release temperatures (for example 68°C or 141°C) are possible.

Fail-safe controls (for pneumatic cylinders)

When the ventilator is opened, a pressure reservoir is filled in addition. This automatically opens the ventilator if the pressure drops.
