For those wondering about the fan curve listed for the G700 at
https://www.harveywoodworking.com/products/gyro-air-g700-dust-processor, it's based on 4" duct, which explains why it only reads to 750 CFM. That was relayed directly to me by Harvey Tech Support. The "max" specs are just based on fan speed at the blower, no duct work. Tech support mentioned they have been getting questions on that. As with any specs, providing context goes a long way to help us understand what we are reading.
From my understanding to get more performance than that out of 4" duct, your HP requirements increase exponentially. Spec wise, that appears to be on par with advertised specs from comparable Oneida cyclones.
I've had my G700 for 1 day, used it on my router table, table saw and just some general dust pick up to see it work. I have perceived a noticeable improvement over my 2HP Oneida V2000. It picks up the dust from further way at the hose end than my V2000 by an inch or so. Also seems to pull harder when I place my hand over the 4" hose end. That was expected since their static pressure specs are higher than the Oneida V2000. This is all subjective I realize, and they certainly are generally equivalent.
I've always found it interesting when using an anemometer flush or 1" from hose end. Put it flush you'll read significantly higher air flow than if you hold it out just by 1". Could be as much as 50-70% more ft/minute. Directing dust or having your hose end as close to source is critical.
G700 initial thoughts
* Unloading from pallet is doable for 1 person, and once it's off, it's ready to plug in and go. The handle install is really optional.
* Mobile yes, but sure wish they made all the casters 360 swivel. That would make it easier to push in any direction.
* because everything goes thought the fan blade, smallish cut offs make a large ding, doesn't sound good.
* compared to the Oneida cyclones, large chunks never make it to the fan blade, they just swirl around awhile until they fall... sometimes never until you turn off the motor.
* Noise level quite good. Keep in mind, my db reader was 84db, no duct work, 10ft away in a 2. car garage size shop. A huge part of that is from the air rushing in at the 6" inlet. Noticeably quieter once you add about 15 ft of duct connected to my table saw, without the saw running. I believe if I eliminated air rushing noise and read db level with inlet ducted to the outside I would be right on the advertised numbers.
* running on medium speed is certainly workable as well, though, the only reason I would do that is if I want a little noise reduction and chip collection still performs well.
