Smoke extract ventilator
Liberator is a powered ventilator designed for the extraction of 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.
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.
The ventilator can be orientated at any angle from the horizontal to the vertical. Its wide range of base types and the fact that it is lightweight means that it can be installed into nearly any type of roof or wall structure.
