Thread: Best quality/value for money Shop Vac for dust extraction

Very nice offer and gesture, Bob.

With a shop vac you don't have to vent outside.

Buy The Dust Deputy Cyclone Oneida at Busy Bee Tools


Get some Bosch 35mm hose found on Amazon . This is quality hose

And possibly a package of connectors or hose adapters

The whole gist of this thread is that a shop vac is not useful for what the OP needs.

With a good dust deputy, why not?

A dust deputy helps save your shop vac and filters by separating the dust . Most shop vacs don't work well because all the dust clogs up the filters, which in turn burns out the motors. If buddy doesn't have a lot of money to fork over its worth a try. With the right set up these things work fabulous. Just sayin'

See the second post of this thread: Best quality/value for money Shop Vac for dust extraction
Shop vacs move about 1/4 of the air needed to run a thicknesser

Yes I read it. Maybe you could read how these work?

The shop vac doesn't pull enough air to draw in all the dust from the source, it doesnt matter how well the dust deputy works.

Shoving a cyclone on a shop vac won't magically quadruple the airflow. You can't move 500cfm through a 35mm (or 50mm) hose without a motor many times larger than what you get in a shop vac. It's physics.

The vacuum pump on our CNC is 7.5kw and it'll only move 176 cfm through a 2" pipe, so you're looking at maybe a 25kw shop vac to move enough air

Pfft! Works great for me and millions of others but to each their own.

Good to see this message getting thru.

Worse still a DD will initially always reduce the air flow thru a Vacuum cleaner and doesn't remove the very finest dust, that still has to be done by a a filter of some kind.

Spiritwolfe, here is some independent testing of a DD showing how it hobbles flow rates.
Flow loss using a Dust Deputy
It shows clearly that to maximise the air flow its better to use VC without a DD and emptying it and cleaning the filters on a regular basis.

BUT
does the vac pump on the CNC -- in conjunction with the shroud around the cutter -- collect most of the CNC's dust?

Hey Bob,

Thanks so much for the kind offer. I've benefited so much from this forum, I was fortunate enough to visit Derek Cohen and pick his very knowledgeable brain on all things dovetail and much, much more and now this.

I'd love to come and check out your setup, I know there is much I can learn from you and hopefully I, in turn can pass this knowledge on.

DM.

My point of view came from what the O.P. was looking for . He has a 2HP dust collector he doesn't have room for so was asking for the best valued shop vac for the $
If he can't hook the dust collector in a garage or other room and the only option is a shop vac , which most people have anyway, then the dust deputy will certainly help make it work that much better.


It will save the shop vac motor and save on filters.
Is it ideal? No! It's not ideal and doesn't get all the airborne dust but he or she could add a WEN system that can be set on a timer to pick up the rest.
WEN 3410 Air Filtration System


Not everyone can afford the best system. Who can't relate to wishing they could get something truly fantastic but just can't afford to do so.


Please disregard the 35mm hose. I just happen to be rigging mine up to a scroll so needed the smaller stuff.


I have the larger Ridgid shop vac and a smaller quieter one for the stroll saw which is going to go downstairs in the basement along with my carving equipment.


Anyway I can hook this up to a :

14" Dewalt planer
4 x 36" belt sander

Dewalt 788


Unfortunately it doesn't do much for
:lathe since it doesn't have a hood or
: vintage bandsaw
They just didn't make hook ups for them and many still don't.


Then of course there is also the fact that one could get a half decent face mask.

I'm certainly not suggesting it's the best dust solution . It's just a simple perhaps more affordable one until a better solution comes along. We can't always go from mediocre to simply fabulous over night. Sometimes it takes stages is the point I suppose I was sympathetic to.


Anyway I normally only post in the carving section but this post caught my eye.
You ever get easily distracted and later wish you just hadn't posted?

for one, I'm glad you did post
