The GAL multipurpose ventilator.
Natural ventilation - automatic fire ventilation - daylight illumination.
Like all of our multipurpose ventilators,
the Series MLL models have a certificate of conformity that enables
their use for smoke and heat extraction applications.
This system enhances the quality
of air and lighting at the workplace, thereby contributing to improving
safety and saving energy.
It has an optimum aerodynamic shape, delivers high extract air volumes
and guarantees permanent ventilation, even in rainfall. In the event
of fire, the system automatically and effectively exhausts smoke
and heat from the building. The special design of this system necessitated
the use of unbreakable, weatherproof, curved glass. It demonstrates
excellent transparency (90%), low weight and outstanding flame-retardant
