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 and smoke ventilation. It fulfills 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.

Product information

The Liberator smoke extraction fan is available in roof or wall-mounted versions:

  • TL: Roof mounted, with vertical discharge. This has four non-return shutters and an aerodynamic cowl.

  • WL: Either wall mounted, with horizontal discharge or roof mounted with vertical discharge. The shutter arrangement is either an insulated flap (for roof and wall) or a louvred ventilator (only for wall). 630mm and 800mm nominal fan sizes.

The shutter version with a flap as termination (WL / FLAP) is opened by a gas spring and is pulled closed by a cable that is operated by a rotary electric motor. In the event of fire, this flap is locked in the open position.

The shutter version with a louvred ventilator as termination (WL / FCO) is closed and held closed by a rotary electric motor. In the event of fire, the louvres open under force of the spring, and are held open. This version is suitable only for installation into the wall.

Both shutter versions have fusible links to open the shutter at a pre-defined temperature.

Features and benefits

  • Suitable for either roof or wall
  • Shutter, flap or louvred ventilator as termination
  • Robust, reliable and durable – made from aluminium
  • Low power consumption
  • Tested and certified to EN 12101-3

Finishes

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.

Certification

Liberator has been successfully tested in accordance with EN 12101-3: 2002, Smoke and Heat Control Systems - Specification for powered smoke and heat exhaust ventilators. Complete CE Certificates of Conformity are available.

Liberator meets the following time/ temperature classifications of EN 12101-3: F200 (200°C for 120 minutes), F300 (300°C for 60 minutes) and F400 (400°C for 120 minutes).

Performance

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.
