Gentleman, this is what happens to impeller blades on a 3 phase, 4 bag dust collector when it sucks up a 6 inch scrap and binds up

By the way, the cost for that impeller is 500 bucks

OUCH!!!

Ummm...that's not good...hopefully it all stayed contained...eBay have one listed by any chance?

I guess I would paint that 6" chunk gold, then mount it on the wall as a reminder...

Double OUCH!

40 years working with fans, never saw one come apart like that.  Wow.  The blades look curved in what's known as "forward curve" configuration, but mildly.  Most material-handling blades are straight.  I wonder if that was part of what went wrong?  Looks like cast metal. 

Wow!

Ouch is an understatement. Hopefully no one was hurt

There are 2 ways to hook the blower up on a DC system. One is where the fan inlet is in the main duct coming in from the shop and exhausts into the cyclone.

The second is the main duct is connected to the inlet of the cyclone and the fan is connected to the outlet of the cyclone and blowing into the filters.

The first way, everything being sucked up goes through the fan into the cyclone .

The second way every thing going in goes directly through the cyclone and the fan is only sucking air that has at the most fine dust, because all the larger debris have fallen out.

A 6" scrap of what?!?

Hope there was no injuries or other collateral damage,

WOW... $500.00

That's not good. Hopefully you'll  be able to find one cheaper somewhere? 

Bet that made a weird noise.

 

The system was designed for the dust to go through the impellers. The other way with the impeller pushing air you need shorter runs. This is a very powerful old one with no other configuration available.

that style squeaks out a few extra CFM..

pot at that.. see how grainy it looks...

the OP may stand a chance of having the manufacturer  make good on it or at least help w/ a pro-rate..

that fan may have been out of balance and vibration stress fracturing may also been under way ...

Oh, man! I'll bet that baby weighs a few pounds...would really leave a mark if it hit flesh.

I can only imagine the noise that made. Musta scared the hell out of you

I have mine router where only the machine that might kick out pieces of wood that big are not going directly through the impeller first. The others like the planner, the joiner, the drum sander, the oscillating drum sander and a few more do go straight to the impeller. This all goes straight to the big flower beds....

   I bet that woke the cat up!

I was just about to post " Good luck replacing  that."

Where do you find such an impeller?

 

That's one thing about the Felder I like; the blower is not in the path of the debris.

The dust collector is an older model Coral. Italian made. Already replaced and spinning just fine. A 2x6x3/4 piece of poplar got shoved from the floor crap into it during a cleanup. Thankfully nothing hurt or damaged except the impeller.
