I have a 8 gallon wet-dry vac that I want to put inside a
cabinet. Roughly 24" x 24" x 29". The hose and cord will come
through a hole in the side. The door will be a simple overlay
style with a latch.

I'm trying to save space but also keep the noise down.

Do I need to add some holes in the back for exhaust? The cabinet
certainly won't be air tight, but is the door and hose hole
enough?

Thanks.


If it chokes it down, you know you need a port somewhere.
Personally, I would think the cabinet doors would act like an air
check valve when the vac is on. Meaning the air pressure would
push the doors out a but to let the air out.

That is why I mentioned the simple overlay door. Plywood on a face
frame is certainly not going to be airtight. A loose latch would
allow it open a little, although more sound will escape. That's why
any opening that I might need would be in the back of cabinet. I'm
sure the difference would be minimal, but just as easy to do, maybe
even easier. Just cut the back panel 3-4" short.


You could always make your own one-way vent by putting a hole in
the cabinet and tacking a rubber flap across it. Most cars have
this system somewhere on the vehicle for when the heater/AC blower
fan in on. On pick-ups, it's behind the seats on the back panel
wall.

I'm not sure I see the point of that. When the vac is on the flap
will open and the air will escape. When the vac Is off, the flap will
close and, well, and *what*?

What would be the advantage of a one-way vent over just an opening in
the back to let the exhaust air escape? What would I be trying to
keep out?



I was thinking of critters and dirt. If you're not concerned with dust,
bugs, and such getting in, then sure, just a hole. Doesn't have to be
big. Like others have said, it only needs to be the size of the exhaust
hole on the vac.
