Door Vent - Sound restricting Relief air for exhaust and A/C

[@zarkov2324]

i'd love to see more videos on bathroom exhaust fan testing and pressure drops vs airflow drops with different sized gaps.

[@EricLS]

I’ve always wondered about this, cutting a huge gap under a door is pretty lame for sound, so it’s cool to see something like this being developed.

Congratulations on the product release! Is it an example of an sound maze? Hard to tell from the images.

[@ecoevo]

@@Xealous C channels, and yes it is a bit of a maze in there. Sorry we should have shown how they come together.

@@ecoevo It'd be interesting to see what 3d printing can do in terms of complex mazes for door vents - albiet while still maintaining airflow / noise

[@beyondzeroemissions]

Pressure equalisation mismatch is a big problem. Could be costing 10% in efficiency on houses that aren't super duper tight.

Im not condoning cutting 25mm off the bottom of the door, but you've got bigger issues if that causes privacy issues. Your new product is a step up for sure but for me its still a bit of an eyesore that's aesthetically more akin to commercial setting

kzbin.info/www/bejne/aZfHXoiggceEfacsi=RcYSLLPykXTsZp9O Everyone seems to accept these things in residential homes? From what we have seen, commercial settings tend to get more of a louvre design.

Do you have a video on how to install it?

[@ecoevo]

We are making that one next week. Sorry about that. ☺️

[@deyeaus]

@@ecoevo thank you. What is the little handheld device you use to show airflow? Do you sell them?

[@albertt7784]

That's why you guys need to move over here to Sydney. Away from the "cold and miserable Melbourne"!

[@ecoevo]

Yeah, but not way from all the mould. It gets cold there too.

[@bradmason8334]

i didn’t see the acoustic difference

@@bradmason8334 We will be presenting some offical data soon.
