Draft Stoppa Exhaust Fan Self-Seal Casing

One significant source of drafts is from exhaust fans in kitchen and bathrooms. These fans often open directly into the roof cavity of your home allowing large amounts of air movement. The Draft Stoppa is self-seal casing for ceiling exhaust fans that can be fitted over exhaust fans in new homes as well as being retro-fitted into established homes. The Draft Stoppa is an inexpensive and efficient way to prevent cool or warm air escaping to or entering from a roof cavity.
Made entirely from recyclable, fire retardant materials, the DraftStoppa is simple to install, requires little maintenance and can be fitted over most standard exhaust fans in new homes as well as being retro-fitted into established homes.

* The diameter of the DraftStoppa is 33cm 

The DraftStoppa®

  • Prevents hot or cold air entering from the roof cavity.

  • Prevents polluted air or cooking smells from entering into other parts of the home or workplace.

  • Exceeds the Sustainable Energy Authority Victoria ‘First Rate’ energy rating performance level requirements for a totally self sealing exhaust fan.

  • Is economically priced and adapts to most major ceiling exhaust fans.

  • Fits most standard and 3 in 1 type ceiling exhaust fans.

  • Is simple to install and opens and closes effortlessly without loading-up your ceiling exhaust fan motor.

  • Is fully recyclable.

  • Testing by Complex Air Conditioning Pty Ltd, and reviewed by the Victorian Sustainable Energy Authority, indicates that in areas where ceiling exhaust fans are in use this can give an energy saving of up to 30%

    Test results concluded that in Winter conditions with an outside temperature of 1ºC and an average internal room (10m x 4m x 2.7m—volume 108m³ and an ambient internal temperature of 15.5ºC), the cold air inflow from the roof cavity through an unsealed fan into the room was measured at 13 litres / second.
    This means that in every hour 46.8m³ of cold air would have entered the room and the total volume of warm air would be replaced every 2 hours and 20 minutes at a huge reheating cost.
