Flowhood vibration

How are you guys reducing the vibration from your flowhood? The table I built is horrible lol I’ve had plates and jars fall off it while working

I used some foam weatherstripping to mount my blower motor to the hood to reduce vibration...

I put some ~1/8th inch rubber under the whole FFU, which reduced everything to a low level. But even without it wasn't shaking anything off the table! You sure the blower is working right? It shouldn't be vibrating that much, could have some balance issues.

Agreed, if your blower is shaking that much something is way off balance in the fan.

Have some medicinal mushrooms and want to get the most out of them?  Try this double extraction method.

What do you mean by off balance? I have to choke the fan about 90% to achieve “laminar flow” it’s a 24x24x12 Flanders with a Dayton 1TDU2 blower

This seems sus. At 0 resistance that blower only does 1100 cfm? Am I looking at the right one? What's the resistance of the filter?

Laminar flow is overrated and most laminar flow filters I have seen are not 12" thick.

You know when they put tires on your car they have to put those little weights on the wheels to balance them?  Cause otherwise your car would shake so badly you couldn't drive it. 

It's probably a defect in the blower, unfortunately there's not likely anything you can do about it.  But that's why it shakes, because it's off balance - more weight to one side as it spins around, throws everything off.
