    OK, but typical inline and bathroom fans (85m3/hour) are not man enough to fully open flap
  

*by F***M on Reviewed in the United Kingdom on 17 March 2023*

Product is easy connect to flexible ducting or rigid pipework, but the one way value only partially opens with the air flow from a typical fan and thus impedes the air flow. I found the best result was to orientate the axis of the flap at about 10 degrees off the vertical (when mounting in a horizontal duct), so that gravity can still close it, but so that if offers less resistance to the air flow. If you install it with the flap axis horizontal, the air flow must lift the full weight of the flap (which it can't).Also, the flap can make a bit of noise when the wind outside disturbs it.

    Works fine
  

*by C***S on Reviewed in the United Kingdom on 14 January 2023*

Had 2 seperate fans blowing into the same duct causing backdraft when only one in use so fitted these ending the problem. Also stops cold air coming in when the fans are off. They do need to be fitted so the  flap is blown "up" to open so that it's own weight closes it.
