Has anyone any experience of using these / recommendations for a specific type.
I’m getting a quiet 6 inch inline fan but there seems to be quite a lot of noise generated from the hose itself.
In my case the hose needs to be movable.
Thanks
There are a bunch of posts about this.
Search for “insulated duct” and you’ll find them.
Here’s one:

It really worked for me! but it won’t silence your glowforce completely 
Can’t remember the specs of the hose anymore what i bought. But if you have a 3D printer
i did make a adapter for the glowforce to the hose!
if you want to edit it i have it in inventor format too!

I did, and I’m not sure it made much of a difference. When I changed my layout it was too big (not really made to be cut down) so I swapped for a regular hose and can’t tell the difference.
You also said it needed to be movable, once opened they are a beggar to squash down again. (true of both sorts but much worse with the insulated hose).
I find the bonus of the insulated hose is that the microtears that you will get in the hose are now dumping into insulation instead of my room…it lasts longer

It definitely made a difference for me. I purchased the insulated hose shortly after acquiring my glowforge and immediately noticed a difference in the noise level. It was several more months before I added the inline fan and the noise level drop was much more remarkable, wish I had made that investment from the start. With a move, the insulated hose did not survive and I haven’t replaced it and not sure that I really miss it now that I have the inline fan.

There will be little benefit to an insulated hose if you are using an external duct fan.

That’s my setup - and it’s worth it.
