Input on a potential purchase of a Dust Extractor (Processors) Questions?

[etds4u]

I've been running my G700 over the past year (with Oneida 6" diameter Super Dust Deputy installed ahead of inlet), and have observed almost zero change in the on-board G700 pressure gauge during this time (I completed a filter cleaning cycle recently, but it made very little difference). I ran over 2000 square feet of white oak flooring thru my 22" drum sander during this time period, which would have likely clogged the filters multiple times without the pre-separator. I'm not a fan of using the built-in flappers to mechanically agitate the internal surfaces of the G700 filters, since I believe this impacts the longevity and effectiveness of the filters. The minimal performance impact of the pre-separator is more than offset with the benefits of constant performance over time, improved filter life, and impeller protection. Note that I use my G700 with one machine at a time (22" drum sander, 16" jointer/planer, or SawStop ICS), so the G700 is more than adequate for my basement shop.

Interesting, having to add a cyclone to the inlet to prevent the filters loading up excessively. While it will not apply to the US (in the most part) can the filters be removed and the exhaust vented to atmosphere? In Oz very few ducted systems use filters, in fact just about none.

So very recently I had the opportunity to see a Harvey G700 in operation. Honestly nothing you’ll see in videos does this tool justice. It’s darn quite at the low setting, I would compare this too the sound of a box fan and this is mainly due to the air moving over the ripples In the hose. I have video of both high and low in operation but not sure on how I can upload the videos directly from my phone. The high setting is obviously louder but I would go out on a whim to say that my Sawstop is louder just rubbing. Again it’s mainly due to the air moving over the ripples in the hose. But even my video does not do the harvey justice. It is truly that quiet.

I have not moved forward because my father-in-law just had brain surgery. But just sharing information that recently came about as I want to go look at some tools this gentleman was selling. And he gladly showed me his new Harvey G 700. Just sharing this information.

I would also concur on the flapper comment. Dr. adaptation would eventually overtime a erode the fiber of the filter materials. It is clearly honestly better to use compressed air at a specific psi. But this is just my opinion based on my research of information. Common sense with basically told us that using air is less likely to damage the filter versus something physically rubbing against the fabric material. But I digress.

One last comment, do you want less noise or good at the tool fine dust extraction because unfortunately you can't have both. The noise the DE makes no matter how high that is is always masked by the machine being used so I fail to see the problem in that regard.

I have a question not pertinent to the topic, has anyone tried to order a Clearvue lately and if so what is the availability, are there long lead times?

I've been using a Harvey 700 since mid 2021 and have been satisfied with it's performance. Since my setting up my shop is still in progress I'm not going to be critical of the hose arrangement until the setup is finalized. As noted it's quiet, and effectively captures dust from my Harvey table saw and Hammer A3-31, the latter putting out large volumes of chips. Dust collection is more effective from the A3-31 than the table saw, but that's more a matter of how each dust collection on machine is configured, not the 700. It's easy to use, is mobile, and sounds an alarm when the primary bag is full. Visible in the photo is a prop under the dust port to support the weight of the three hoses and prevent the factory supplied (clear) dust port adapter from falling off.

[member=3346]dwillis[/member] I appreciate the feedback. Has you experienced any issues or gripes since you’ve been an owner? I’m just trying to grasp long term ownership benefits that aren’t really available to understand. Anything you contribute to the discussion is much appreciated.

I haven't had any issues or complaints since I've bought the 700. As I mentioned earlier I don't have the machine set up in it's final location, thus the ducts are temporary. One observation, and this is probably unique to each user, is the geometry of how the ducts will be run from the dust collector to the tools. Because the dust enters the 700 on the front of the machine, instead of on top like a "normal" cyclone arrangement, it's going to take some head scratching how to efficiently route the ducts. More than likely the 700 will reside under a cabinet and countertop that's placed against the wall, so some of the countertop will be partially blocked by either a duct coming straight from the 700, or going vertical with an elbow. But each shop is configured differently.

[member=3346]dwillis[/member] thank you. Yes agreed the only thing I could think of is to either place the unit to you could angle the run up a wall in a diagonal. Our secondly just plumb the main run near the unit and connect with a short run of flex or metal ducting to the main run. But yes everyone’s configurations shall or will be different on the basis of budget, space, and preferences based on research.
