The Story

  • FITS STANDARD ROUND DUCTS – Designed for 4 Inch ventilation pipes, ensuring a secure fit for both flexible and rigid duct systems.
  • Easy DIY. Designed to provide anti back draught and fit in between Solid Plastic Ducting, Flexible Ducting.
  • Designed for use in AC, dryer vent, exhaust, extractor or range hoods, heating systems, fans, vents and other residential, commercial and industrial HVAC applications. Best to use with VENT SYSTEMS hvac parts.
  • Duct draft stopper prevent cold air or wind from entering the ventilation pipe. In this case, the flap is installed in such a way that the flap leaves only open into the outgoing air direction. This means that no cold air / wind or smell can penetrate the ventilation pipe from the outside.
  • The backflow Preventer valve is installed by pushing it into the ventilation pipe as far as it will go. The position of the spring should be horizontal when the flap is installed horizontally so that it can be opened and closed optimally. This also applies to the vertical installation.
