Any ideas how to keep this from happening?

[Ray-CA]

Added a cyclone dust separator to my collection system. Using a 15-gallon barrel and it was working great for 30-minutes or so. Switched the system off to add a vacuum attachment to clean the floor and the barrel collapsed.

Anyone know how to keep this from occurring? No obstructions in the hose and plenty of air flow. The sides just sucked in.

Thanks

Last cyclone I looked at recommended using a metal can, not plastic.

I’ve even seen the galvanized cans collapse. The old style paper fiber barrels work best.

I've done the same, your sealing is good and tight.
I don't have a solution. I got tired of all this & bag changing with my dust collector.
So I just vent my dust collector outside.
Might need to reinforce barrel from collapsing or make a connection looser.

Don’t open the system, just get a proper can and be thankful you now have a system that really *****.

If you wanted to get fancy you could add a solenoid actuated breather that closes when you power up the vacuum and open (vents the negative pressure) when ya shut it off.

Place an atmospheric pressure valve on the tank. Requires some silicone, the valve itself and it does not have to be extremely large. When you have your system running, it will close because pressure has built up in the tank. When it shuts off it will fall open at a certain internal pressure once the pressures drop to a certain level bringing in air from the outside without letting dust fly out. But if there is a concern about the dust exiting through it, add a filter, which will block the movement going outside the container.

This is the same kind of setup that your car trunk has when you close it. A flap which will allow for pressure to move when the trunk is closed, and prevent noise from coming inside. Position of the valve is important. The automotive types hang down. When the trunk is closed, they will push open relieving pressure, and swing back closed.

Doing this on a dust-can for your dust collector would push closed when running, without positive pressure, and when shut off, the negative pressure would allow it to swing open, pulling air in keeping pressure constant, and should prevent the plastic can from deforming.

I've got a metal barreled one from Oneida and it works just fine. I think they still make it. It does cost more than the cheapy plastic but works great.

I have a Valvoline oil drum (a small one) that I use for a trash can in the garage. Tried that, and it worked but it’s heavy empty and really heavy when full of saw dust. Went with a fiber-board shipping drum which worked well until I put a nozzle on the hose to clean up under and behind some tools. Collapsed like a tissue paper bridge.

I ended up reinforcing the drum with 4-vertical ribs with cross bracing at 4-levels. Now I get just a small amount of “****-in” but the system is fully useable.

Thanks for all the suggestions.
