As an alternative to permanently open ventilators with consequent heat losses, K G Smoke Dispersal's automatically opening ventilators are in effect horizontally pivoted windows which provide the required smoke-free access routes for multi-occupancy buildings.
The unit has a fail-safe operating mechanism, held closed in normal circumstances by two electromagnets within the frame.
When the electromagnets are de-energised, the sash is pushed into the open position by gas springs.
