Hi all,
I have a Laguna cyclone dust collector that currently seems to be filling up the bag on the filter canister faster than the barrel.
any ideas as to why this is happening?

I am running 2 – 10’ hoses off the original Y that came with the collector, one is connected to my saw, the other gets moved between the BS, jointer and Dewalt planer. It almost seems like the planer is blowing it right past the cyclone section and into the filter bag.

Check for leaks between the cyclone and the barrel. If you get a bad seal in this area will cause the DC to bypass the barrel and send the dust to the filter.

that was my thought as well, but it seems to be sealed

This guy had a problem and here is his solution. It might help yours if you don’t find another.

If you are using the Dewalt 735 Planer it has it’s own blower fan. It is not really meant to be hooked up to a dust collection system, and if I recall it says as much in the directions. Just a thought, not sure about the other issues.

The only think that even comes to mind is exactly what English said… sounds like there’s a leak in between the cyclone and the collection barrel. The cyclonic effect doesn’t really work if there’s a pressure differential between the two, so even a small leak can really throw things off (I’ve done several times on mine accidentally).

If I remember correctly, this Laguna has some sort of hose attachment for the bottom of the barrel to keep the collection bag from getting sucked up into the cyclone? Is there potentially a leak there? Are you using the bag? Those are just guesses, but I’m stumped for ideas outside of the seal.

I would go with English. The 735 fan only clears the chips from the planer doesn’t affect DC at all. Manual states fan-assisted chip ejection will work in conjunction with independent dust collection systems. Shop vacs are not recommended they don’t have to copacity to keep up with the planers ability to produce chips.

Just to clarify something about 735,according to the manual ,a 735 is not recommended to be connected to most shop vacs but not all,a large Ridgid vacuum connected to a Dust Deputy can handle the 735 chip blower,the only trick is (as it is with full size Dust collectors)to turn the vac/dc on before the planer.

I’m not saying its definitely the planer, just offering a troubleshooting option to look at. I have the same planer and it has a jet engine of a chip ejector! A simple test would be to use all of your other tools normally with the DC, but not the planer for a project to see if it cures the issue. Or don’t, its up to you.
