I have a 3 phase dust extractor for sale if you're interested, 2'sq and 4' tall. Not sure of the make as there's no makers panel on it, but it's all dark green with a tray at the bottom and a 2'sq filter section above this. There's a shaker arm on the right side, a rectangular exhaust at the back, and it has a 5" or 6" inlet on the right side.
It's in excellent condition, just came from a college. It's still tested as well.
