A little out of my price range, but I'll admit to a little DC envy. Is it 110 or 220, listing didn't say. Says it's 54 inches tall, which seems short for a 35 gallon drum as shown.
The G0440 I have was purchased used on Craigslist for $600 about two weeks ago. It had probably seen about 100 hours of use (according to the seller) and was squeaky clean. It is a 220v 2hp unit that, at the top-height of the motor is somewhere around 94" tall. There is nothing subtle about this machine -- heavy gauge steel is used in all the components. NOTHING flexes or bends easily (or at all, for that matter!) on this unit. My son and I took about 6-8 hours to install it, including some modifications to the garage wall to be able to support it.

This G0440 is an older, now-discontinued unit (circa 2012-2013?). Grizzly has a few "new" flavors of the G0440 which has seen some minor upgrades and extra components (e.g., the "stand" is now standard, not optional. HEPA filtration upgrades are also part of the package). I think mine originally sold for around $1300, plus shipping which would put it close to $1600. If I could have gotten the 3hp unit (G0441) for that money ($600), I'd be in heaven! However, I can't be too greedy, and this unit is likely overkill for anything that I will throw at it in my hobbyist shop. It will also likely last until I'm in the grave.

I have mine mounted to the wall, which was no minor feat. I probably over built the mount a little, but didn't want to have any issues later which could results in catastrophic damage or injury.

The drum is a little bit small -- I considered modifying the mounting height to allow me to use a 55 gallon drum (the drum supplied is the same diameter as a 55 gallon drum, and they do sell a $166 "upgrade" to increase the supplied drum size to 55 gallons), but ultimately decided that I would stick with default as I was already a little bit close on clearance at the top of the motor height. It'll be fine for what I do.

The G0440 is supplied with a polyester pleated filter on the air output that has around 90 s.f. of filtration surface area (and a rating of MERV 11). It has an internal brush mechanism (operated by a pulley system) to clean the pleats, and honestly doesn't work very well at that. I had set up my old HF unit with a Wynn Environmental 13F230NANO (MERV 15) output filter that has something like 230 s.f. of filtration surface area, and am transferring that filter to the G0440. This particular filter has a nice cage on the outside to let you "beat on it" to get the dust out of the pleats and will also let you use an air hose to push the dust out of the pleats when necessary. I have an "Omega Lid" on a 5 gallon pail attached to the bottom of the Wynn filter to catch the fine dust.

Sorry to hijack the thread!

No hijack Michael. All discussions of dust collection build awareness of the risks of stray sawdust to your lungs. What a great find! Good move to reuse the Wynn filter.

cleaning a filter ''to clean'' reduces it's cleaning efficiency...
and a clogged filter doesn't filter and seriously hurts the efficiency of the collector..

If only new layers hadn't been added....

@Stick486 Kind of a keeping on an edge sort of thing. On my Wynne, I just blow in compressed air and what comes loose with that is fine. You talked about this some time ago, so I just don't overdo the cleanout. BTW, shortened up and straightened our the hoses on my DC and Super Dust Deputy. That enclosure project turned out well. Thanks for the suggestions for the return air port.
