Liberator powered smoke extract ventilator

Liberator extracts smoke and hot gases in the event of a fire. It is suited to most industrial and commercial buildings and can provide both day-to-day ventilation for climate control, as well as smoke ventilation. It fulfils the time/temperature requirements of EN 12101-3, achieving F200 (200°C/120 min), F300 (300°C/60 min) and F400 (400°C/ 120 min) in accordance with EN 12101-3.

Installation options

  • T-Liberator: Roof mounted with four spring loaded shutters and an aerodynamic cowl
  • W-Liberator/Flap: Wall mounted with a single insulated flap
  • W-Liberator/FCO: Wall mounted with louvred ventilator

Shutter version with a flap as termination: opened by a gas spring and closed with a cable operated by a rotary electric motor. In the event of a fire, this flap is locked in the open position. Fusible links to open the shutter at a pre-defined temperature.

Shutter version with a louvred ventilator as termination: opened by a spring mechanism and closed by a rotary electric motor. Fusible links as additional safeguard to open the shutter at a pre-defined temperature.


All steel components are polyester powder coated to RAL 7032.

Bases and installation

WL / FLAP can be orientated at any angle from the horizontal to the vertical. For all Liberators, their wide range of base types and the fact that they are lightweight means that they can be installed into nearly any type of roof or wall structure.


Liberator produces airflows of between 3.6 m³/s (12,900 m³/h) and 8.9 m³/s (32,050 m³/h). Its noise output ranges from 58 to 87 dB(A) at 3m (sound pressure level). It is available either as single or two speed.

However many projects require extract systems that are outside of the standard Liberator range, either in terms of the extract rate required, or the pressure drop of the system through which the fan is extracting. Please contact Colt.
