Thedreamer Posted April 21, 2019 Share Posted April 21, 2019 Starting to understand what I need for the ducting order. Our plans show a silencer. I have the option of ordering a longer silencer and those that have more insulation in the silencer (50mm to 100mm). What size and thickness of silencer have others used?

Jeremy Harris Posted April 21, 2019 Share Posted April 21, 2019 I'd opt for the biggest silencers you can fit (and afford) as my experience has shown that running without silencers was noisy, and with limited space I ended up having to make custom ones to fit. They are as large as I could fit in the space available, but we still get some very slight noise when the MVHR is running flat out, not annoyingly loud, but as the house is so quiet it is noticeable at times. 1 Link to comment Share on other sites More sharing options...
jfb Posted April 21, 2019 Share Posted April 21, 2019 yes go as big as you can - I also ended up making my own and it has reduced the noise on the supply side to inaudible 1 Link to comment Share on other sites More sharing options...
Gone West Posted April 21, 2019 Share Posted April 21, 2019 As others have said, go for the largest that will fit. I fitted a 600mm long by 250mm diameter attenuator as that was the longest I could squeeze in on the supply side and it's silent. 1 Link to comment Share on other sites More sharing options...
