Back Draft Fire Rated Ventilator

Back Draft Fire Rated Ventilator


The Backdraft range is Windmaster International’s latest addition of progressive innovation. Backdraft is a fire rated Turbine Ventilator designed and tested to extract excessive smoke from a building in case of fire. It will contain the fire and maintain a safe smoke level in accordance with the EN standards.

This ensures that people will escape the disastrous effect of suffocation by smoke inhalation during fire in a building.

The Backdraft turbine ventilator is not only a lifesaving safety device but also a natural ventilator that ensures positive airflow for day to day ventilation in your building.



A major benefit of the Backdraft turbine ventilator is that it requires NO maintenance, unlike other smoke ventilators. It is a low cost solution and provides more advantages than standard static smoke ventilators.

The unique patented design of the bearing system withstands and maintains temperature of 300 degrees Celsius for a period of 30 minutes, as per fire regulation codes. Tested and proven, the Backdraft range of turbine ventilators will suit your needs for effective positive day to day ventilation and at the same time provides you the peace of mind of a reliable lifesaving device that you can depend on.

The rotating action of the Backdraft smoke ventilator ensures continuous extraction of heat and smoke in case of fire, maintaining a clear safe smoke layer.



WordPress Data Table


As per regulation, mechanical ventilation requirements for smoke ventilation should be calculated to maintain a minimum of 10 air changes per hour. Due to the variation of extraction capacity, the Backdraft Ventilator is calculated to maintain 10-15 air changes per hour. The below extraction table is to be used at an average of 25km/h to determine the quantity of ventilators required.

Note: The Backdraft ventilator is not designed for Zone-controlled alarm activation smoke ventilation and only to be used as free-standing ventilators similar to fusible link smoke ventilators.
