I have a couple of these Woodriver blast gates in my shop:
They tend to get clogged in the back corners such that they don't close
completely. More often than I'd like I have to get out the air hose and
blast the dust out of the innards to get them to seal. Once they are clean
they work great...for a while.
Is this common with blast gates or are there better ones that don't clog?
I need 2 1/2" gates.

I use the all metal gates and do not have any problem with them not closing completely. They have been in service for years. I believe I bought them at Rockler. Mine are for 4" hose. I don't know if that makes a difference.

From my recent reading, these plastic gates are prone to clogging, especially
in systems with relatively weak air flow.
Some people modify them by clipping off the back corners so the debris is
pushed out. Yes, you lose some air flow at the open gate, but less than
when you are losing air at a gate that is supposed to be closed but isn't
due to the clog.
I'm going to try that. If it doesn't work, I may try these, although it
seems like the open slot would mean even more leakage.

I don't use nor will I probably ever use blast gates. I do not have a
multi man shop so I only need to use my DC for ONE tool at a time. I
have a 30' long flex hose that comes directly from the DC to any of the
6 machines that use the 4" connection. The ends are flared so hood up
My set up is just toooooo easy and efficient for me to consider
complicating with Y's or blast gates.

My set-up is far from "complicated" One Y, two blast gates, right next
to each other.
One gate is dedicated to the miter saw, the other is for basically the same
hose set as you describe. It takes nothing more than a quick push-pull to
swap the air flow.
I found that I use the miter saw so frequently for quick, one or 2 cuts,
even for non-shop related tasks, that it deserved a dedicated DC connection.
In addition, the miter saw's DC connection is on the left of the saw and
the entire rest of my shop on the right. The dedicated connection for the
miter saw is more efficient than just a single hose, even with the clogs.

Solution to problem. Singular.
On occasion, yes. But the air line I ran to the shop last winter sure
helps with that task.
The set-up is still more efficient, even with the occasional need to clean the
gates. If I had to do it before every use, then, no, it wouldn't be more
Has every improvement you've made in your shop/house/etc. been 100%
perfect the first time or did some require a bit of tweaking?
If you never have any issues whatsoever, then I bow to your greatness. ;-)
Nooooo. I finally went to the single 30' hose to cure issues with
Actually your issue is a long documented problem with blast gates and
complicated runs. I decided to simply run the flex hose with the flared
ends to start with.
I was watching a YouTube video a few weeks ago, OMG, me too. The guy
had a Very complex DC system and had no suction. Probably 6~8 gates and
as many Y's. All sent from the tool to the ceiling and the system could
not pick up debris from his DeWalt planer. He thought it was because
the DeWalt planer blew out the chips vs. simply being sucked out of the
He clearly did not have an understanding of how all of this works.
Blast gates are not for multi man shops, they are for multi tool shops.
Most larger shops with lots of large tools have a central dust collector
permanently hooked up. Many not only have blast gates, but gates that
open automatically and systems that turn on when each machine is used.
Derby seems to have a problem probably aggravated by the Rockler gate
that doesn't open fully, and by the gate recess getting clogged, not the
hose getting clogged. Jointers and planers can clog hose, not so much
saws and sanders.
I would hate to walk around connecting all my tools to hose each time I
used them. It's aggravating just having to move a gate. I already have
a Long Ranger so I can turn on the collector from anywhere, and that's
aggravating enough that I understand why guys like their machines to do
all that for them automatically.
I made my own gates and they never get clogged, ever, but I still have
to open and close gates manually...ugh. Well, I did have one clog and it
was a t-shirt stuck in the middle of my table saw hose... Still no clue
as to how that thing got in there. I'd have a hard time getting it past
my saw blade and into the chute...

I never mentioned Rockler gates and I never said anything about them not
opening fully. In fact, I said the exact opposite.
Wasn't it you that just commented on another member's "reading ability"?
(see the Forstner bit thread) Pot, kettle, etc.
Someone mentioned they use Rockler Gates [Bob], not that that matters.
The picture you referenced indicated to me the gate would not open all
the way because of the button preventing it from opening fully. Rockler
gates look exactly the same, and probably are.
That was in response to Kevin stupidly claiming "video was for people
that can't read." I simply remarked perhaps a video would not help him,
[considering his proclaimed reading superiority]
Of course, you're too freaking dumb to figure that out. I thought you no
longer read or replied to my messages?
