MikeSharp01 Posted March 6, 2020 Share Posted March 6, 2020 We are just getting sorted to run the MVHR pipework and while I had defaulted to round outlets I saw this And wondered if anybody had tried MVHR with slot outlets and if so what was the experience like?

RandAbuild Posted March 6, 2020 Share Posted March 6, 2020 Now they are very neat! I have vent envy ? Link to comment Share on other sites More sharing options...
Dreadnaught Posted March 6, 2020 Share Posted March 6, 2020 (edited) I think they are termed "linear diffusers". I like them too. Here's an example: https://s3-eu-west-1.amazonaws.com/monodraught/downloads/literature/linear slot diffusers.pdf Edited March 6, 2020 by Dreadnaught Link to comment Share on other sites More sharing options...
Dreadnaught Posted March 6, 2020 Share Posted March 6, 2020 (edited) I see they have veins within but it looks like they are a form non-return valve. I wonder how a linear diffuser could be selectively attenuated for the balancing an MVHR system, either supply or extract.

I was wondering that as well there must be a way and your link sort of helps but it looks like it might be tough none the less. Link to comment Share on other sites More sharing options...

I think it is possible to locate the flow control away from the diffuser, presumably near the manifold, by using duct butterfly valves. This could be a solution. I wonder if anyone has used duct valves for attenuation rather than diffusers. Edited March 6, 2020 by Dreadnaught Link to comment Share on other sites More sharing options...
Adam2 Posted March 6, 2020 Share Posted March 6, 2020 Looks very nice, think that might be one where my wife says yes until she sees the cost ? Link to comment Share on other sites More sharing options...
Dreadnaught Posted February 12, 2021 Share Posted February 12, 2021 Resurrecting this old thread. The MVHR extract vents in my kitchen either need to go though a steel beam or can be a linear diffuser in a wall without needing cut a hole in the beam. But I am still not sure whether linear diffusers are good as extract terminals. I wonder, has anybody used a linear diffuser in their MCHR system? @MikeSharp01, did you use one in the end?
