Fire Open Position |
The Fire Force dual-purpose ventilator, designed and manufactured by Ventrite International, offers a patented design to provide maximum exhaust area under fire conditions, providing a fully weatherproof unit in its closed position. It saves stock, saves buildings and most importantly, saves lives. In the event of a fire the louvre blades would open without failure by means of a unique spring loaded system. The louvres in the open position are also supported with a special locking device to prevent wind from shutting it in high velocity wind regions. They are effective in keeping escape routes clear of smoke and helping fire fighters see and tackle the fire.
Fire Force is also a highly efficient louvred natural ventilator which enhances comfort and productivity by providing cooling ventilation, releasing heat build-up and releving psychological stress by giving natural day light in summer. In winter, it conserves heat in its fully closed position. Fire Force louvred ventilators are also recommended for both roof and side wall applications.
