I wanted a low-profile vac that could be hidden away under my table. Shop-Vacs are too large and I didn't want to source making my own. I saw FoxAlien launched this HFS vac and dimensionally it looked perfect. I personally dont use the speed control aspect of it. I feel its noisy when low, and its not that much more noisy when going to high. There's more whine as you'd expect from the higher RPMs, but its not like a world of difference in loudness. That said, I just often crank it to full and assure dust removal is at its most. I use this with an air-cooled VFD spindle. I wasn't sure how things would work with my spindle blasting air down into a dust-shoe + the vac. If that would cause any issues. So far, its been pretty good. Wood and aluminum chips got sucked up without problems. The build quality feels pretty nice. The back-door that covers up the filters has a pretty strong magnet that keeps the door shut. I feel the suction isn't too bad. It wont be as much as a shop-vac that uses 2" hose but I mean..that's a given. Anytime you go to 1.25" hose vacs, you loose some flow. Far as I'm concerned, it sucked up the materials I expect to cut. So I honestly can't complain! Very happy with this little thing. It's nice to have something just hidden away that's ready to go. I use this to keep my Vasto clean, and put an extension on the hose to clean off my lathe. I do recommend running a cyclone/dust-filter in-line. The dust collection "bag" on the HFS is pretty small. You'll fill it up fast, and plug filters up easily with fine wood dust. Cyclone filter/Seperator in between your machine & HFS aids in keeping the vac clean!
