I have a Jet 2 HP 2 stage dust collection system. I was wondering if
any of you have any tricks to make it quieter. For example, could I
wrapp the impeller housing in foam or something. I know I should not
affect the motor cooling or the air escape....
I've also thought about building a little closet for it with enough
opening to allow air flow.
I have mine in a corner with a couple of 4' x4' ceiling insulation panels
leaning against it.. helps some...
In the next shop, it will be outside, in an insulated box with a cooling and

I leave the DC on between the intervals when I'm using other noisy
tools. It's nice to have quiet sometime. Otherwise I keep having to
walk over to the Dc, turn it off, go do something, then return to turn
it back on. BTW, I'm considering a remote control.....
Just curious, and I've no tools to speak of, just working to get
started, no dust collector, a totally amateur response - but I had
planned to have a master switch feeding all of the (currently
non-existent) power tools and figured I'd have a current relay to
control the dust collector. Any reason why that wouldn't work? I've
not researched it, but it seemed an obvious idea so I'm sure it's been
done - unless I'm missing something obvious in my obvious idea. On
when the tool's on, off (after delay) when it goes off.
The problem with a remote is that like the one for the TV, you have to remember
where in the hell you put it... I guess you could clip it to your belt or
My workbench is pretty much in the center of the shop, so I just mounted a box
with remote switch in it on the bench in handy-reach position....
I gets to be pretty automatic to take a step or 2 and flip the switch...
An outlet box, switch and 3 feet of wire was a lot cheaper than a remote control

When I added the remote to my dust collector, it came with two handheld units.
I velcroed one to the front of my bandsaw and the other to the overhead guard of
my tablesaw. I can always find one of them handily.
I put mine outside for two reasons:
2) Even though the bags collect most of the dust, they do leak some.
Therefore I put the DC in a shed just outside the garage so that the
extra-fine, extra-harmful dust goes outside.
The downside to having it outside is that I have to go outside to turn
it on or off (I know, easily fixed), and that it does suck some of the
warmer garage air out. Small price to pay for much less dust in the
I can't imagine it, myself. I'll mow my lawn when, and if, I damn well
feel like it. If I don't water it during August, it won't grow, so I
don't have to mow it. Problem solved.
Granted, it's a bit ...crunchy...
My suggestion is to build a closet, that is what I'm going to do. My HOA
wouldn't like it if I put my DC outside either.
The muffler must reduce air flow to dampen the sound. I used a sound
level meter in my shop and got the following readings:
DC - JET 1100 with Canister and Remote 1.5 HP
- At motor - 92 dB
- At duct where muffler would be - 88 dB
- Against lower bag - 114 dB
- Air leak at a 4" dust port - 92 dB
- Ear level at my lathe 15' away - 72 dB
If the velocity of air into the bag were reduced, then that would reduce
the sound level "against the bag" significantly. So, if I were to get
that muffler, then the quitest my DC would be is 92 dB, since the
muffler would have zero effect on the sound generated by the motor. 92
dB is still loud, but the reading was taken at 6" away from the motor.
The muffler is advertised to reduce sound by 5-10 dB, and it probably
will, but at the expense of air flow.
Not all tools are as loud as the DC. My bandsaw isn't that loud and my
lathe only puts out 55dB at high speed.
