Therma-vent smoke vents

Therma-vent smoke vents are designed to reduce smoke build-up, thus providing a safer escape route for occupants, and access for fire-fighting personnel. The system can also be utilised to provide natural ventilation.
A typical smoke ventilation system includes Thermavent smoke ventilators (Opening Vents (OVs) or Automatic Opening Vents (AOVs)) located at the highest point of an escape route staircase or at the top of a smoke shaft. Smoke detectors and manual control points are normally located on each floor. The system can be controlled by a Therma-vent control panel.
