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.
