Was just out working on my 2x blower box, and you're right! The snout can be removed and so can the inlet screen! One of these days I might take those out. For some reason I was thinking the inlet screen was part of the housing sheet metal...
Anyway, speaking of my blower box, I finally got the one blower out of the garage shop and into the cheapie patio box with the other one. This setup could've been much nicer to look at but I simply don't have the time to play dress-up with my tools
...
I got the preliminaries done last night after dark, took this pic this morning:

looks much better than it has been. The storage container acts a muffler, and semi-stink filter. I have a 16 pound bag of cheap charcoal briquettes wrapped in 1/2" screen and stuffed against the far right air-out side. It's great at reducing the air noise, and while not hardly the perfect filter, it does cut the leather and plastic smell down by about 2/3.
Plenty of room inside for 2 blowers, the box dimensions are perfect
-note the 2 holes showing daylight thru (and above), these are for the motors to draw outside cooling air.

I after getting all the plumbing buttoned up I started stuffing
fiberglass between the blower and the box. Best I can tell
there's no part of the blowers touching box. I left the space
in between them so the motor's cooling air isn't totally trapped.
(it got dark and my flash doesn't work, so the pics are grainy)

There's 2 layers of glass resting on top. Before closing the lid
I pushed the glass towards the back of the box, there's a good
2" of space for the motor air to find its way out.

The box is now resting on a pallet, with 2" of foam rubber and a laser of glass as cushions (was too dark to get a pic).
For over 15 years I've had one and for a long time two of these blowers in my basement stairwell for the basement lasers. Being down there, they've always been fairly quiet, never had a neighbor complain (till a bearing in one started screeching
)... Both these blowers running, on the driveway on the side of the garage, are just as quiet. Our closest neigbors, who's bedroom window is about 60' from the blowers, can't hear them running inside their house even late at night.
There is one little flaw in my system- if both exhausts are plumbed into the muffler box, then both blowers must be on, or backpressure pushes the exhaust right back into laser with the blower not running. For now I'll just keep them both running.
So no blower in the garage pushing smoke into the room finally, which is quieter, and the wife can open the freezer door all the way now-- We're happy!
