  • The tradies choice mechanical damper has a 200mm diameter barrel with 5mm silver foam insulation. The barrel has a mechanical actuator on the side which will mechanically open/close the damper once it has been wired to a on/off switch. Perfect for heat transfer kits and other applications which may require a mechanical damper.

  • The tradies choice mechanical damper has a 150mm diameter barrel with 5mm silver foam insulation. The barrel has a mechanical actuator on the side which will mechanically open/close the damper once it has been wired to a on/off switch. Perfect for heat transfer kits and other applications which may require a mechanical damper.

  • A backdraft shutter is used with inline fans and duct, to stop air flowing in the “back” direction. It has “butterfly” wings and a very weak spring to minimise airflow reduction.
     
    Made of metal, this backdraft shutter will connect to 100mm ducting.

  • Metal damper with additional 240v actuator.

    This mechanical shutter is perfect for zoning requirements for a heat transfer system. Its 240v so would require an electrician to wire the damper to a switch. This will give you the ability to open/close the damper as and when required. This is particularly useful if you wish to shut off a branch of a heat transfer kit (eg if its a spare bedroom seldom used for example).

    This kit consists of a 250mm metal zone damper and 240v actuator – read the 'installation example' tab below for more information and example diagram.

    This is a single room option only – multiple room zoning requires more components and would incur a consultancy fee for us to put together the necessary kit. If you are interested in this please contact us.

  • A simple and inexpensive way to stop standard ceiling exhaust fans from letting warm air out or cold air in. The draft stopper fits over fans that are smaller than its diameter of 330mm.
     
    Depth: About 200mm with flaps open
     
    It contains a pair of balanced shutters which open when the fan is turned on and close under their own weight when the fan is turned off. The Draft Stopper aims to reduce energy costs by preventing hot or cold air from entering or escaping the building via the hole in the ceiling for the exhaust fan. It's an easy and effective application to complete the draught proofing of your home or business.
