Right. The whole system is designed to be rather low velocity air flow: that's the key to good HVAC for studios: high volume, low velocity. Internally, inside the silencers, it's only around 150 to 250 fpm., and around 200 - 250 at the registers. Higher in the round duct sections, of course (600 to 800, with the AHU going full blast), but those aren't lined with this liner! In any case, the liner is rated for flow velocities up to 6,000 fpm, so I think we should be good with 200 fpm... :) Those fasteners inside the silencer boxes should be fine: maybe very slight turbulence, but nothing to be worried about.

However, I would not use them inside the sleeves: Those do need to have smooth sides. The good thing about the sleeves is that they are accessible from inside the room, so if the liner does come loose, you would be able to replace it without too much hassle.

There should be no dust build up on those fasteners, since you'll be using really good filters in the system... :) There should be no dust at all. But do close off the sleeve holes while you are installing the boxes, and until you are ready to install the sleeves, to keep dust and debris out. Tape heavy plastic across the holes, for that, on the inner-layer of wood.

Looking good, Tom! It's really nice to see how the place looks with lights in it! It's beginning to look like it might be a studio one day....

Hi All,

Geeze finally finished a box today! Tricky tight fits as some of the timber wasn’t cut accurately enough... lump hammer required for persuading.

The new layout will give me a lot more flexibility for storage so I’m well happy with that!

Gladly we know the silencer placement for sure...just not the mounting, so we’re able to place them for now : )

I have some things to work out...the first box went up ok...with 10mm clearance : ) nothing broke, no one or thing damaged...just managed to get it up at the end of today!

More fun tomorrow then build the next one in half the time : )

Precision engineering! That looks like it wasn't such an easy job to get that up there... I hope you didn't put it in upside down! :shock:

(Just kidding... I'm sure you got it right...)

Well, we have a fairly smooth winch towards the intended placement... we actually ended up using our feet to encourage it in when we could get behind it... bracing off the concrete beams above. We nudged it almost into position but left it on 25mm square steel section to lift it for rubber placement and sleeve assembly.

We used some air bags to lift the box when necessary...which was slow and stiff but did work. I’m going to look into pneumatic hose connections to connect the 4 together and use the compressor air so we aren’t hand pumping all the time... I’ll regulate the pressure so need to decide what pressure they can handle...

Here’s the box now and the new one in construction!
