Linear Natural Vent

Smoke hatch skylight is suitable for buildings with fire protection, smoke exhaust and lighting as main requirements and ventilation as auxiliary requirement. This kind of ventilator has low wind resistance coefficient and its opening angle can be controlled through electronically, with smoke exhaust rate at its highest when opened fully to a 90-degree angle.


  1. The "nail-free and glue-free waterproof structure " patented technology completely eliminates leakage hazard
  2. Broken bridge aluminum profiles can be used in low temperature areas to keep heat and thermal insulation to prevent condensation
  3. Support connection with firefighting service and offer multiple functions including smoke exhaust, ventilation and lighting
  4. The opening angle can be set, it can be fully opened within 60 seconds, high performance of fast smoke exhaust
  5. The ventilation and smoke exhaust vent is consistent with the roof opening, that is, the effective ventilation and smoke exhaust area is same with the roof opening area, which achieves the greater ventilation and smoke exhaust efficiency
  6. Small wind resistance coefficient
