Draft Blocker – Backdraft Damper Duct – Draft Stopper – Backflow Preventer – Inline Fan Vent – Vent Deflector (4” Inch)

  • Back draft damper is made for insertion into inch ventilation ducts. The backflow damper RKI opens and closes automatically. It has a strong spring and can be installed either horizontally or vertically. The flap is suitable for retrofitting, since it is completely inside the duct
  • Damper has 2 valves, designed for use in air conditioners (AC), dryers, exhaust, extractor or range hoods, heating ducts, vents and other HVAC applications
  • INSTALLATION: The backflow flap is installed by inserting it into the ventilation pipe until it stops. The position of the spring should be horizontal for horizontal installations so that it can open and close optimally. The Backdraft shutter is installed so that the damper blades open only in the outflowing air direction.
  • The backflow flap opens and closes automatically at low air volumes. It has a smooth-running spring and an internal foam strip to keep the blades from rattling and can be installed horizontally or vertically
  • Back draught valves can be inserted into ventilation ducts which are flexible or non flexible. Cannot be used with plastic ducts as the sizes are different.
