One thing I have personally noticed while sanding with a Hummel sander and not using a bag is that major clumps of wood fibers collect and shoot out the Hummel. This is not good since if you roll over the clump of dust it will create a divot in the floor. So, upon seeing that issue we had to stop using our bona dustless trailer with our Hummel. The Bona trailer is far superior in dust collection to the setup Hummel provides. The bag lets way too many dust particles through and you can see a major difference. With the Bona trailer you virtually have no dust while the bag lets dust settle on the counter.
So, in light of the situation I set out on a journey to make my Hummel sanders work perfectly with our Bona trailer to get best of both worlds, perfect sanding WITH dustless sanding. While some contractors might say to just “avoid” the clumps of fibers that still leaves room for error and not a proper solution to the issue at hand. The first step I took to figure out how to fix the fiber issue was I called Hummel in Denver. Russ Watts was the point of contact. Upon talking with him It was settled I would need an Oneida Vortex.
The Oneida Vortex is a device to diffuse the extra CFM’s the Hummel generates by its massive blower. The reduction of CFM’s by throwing them out of the HEPA filter lets the vacuum have zero back pressure. The vortex then allows our Bona vacuum to properly suck up all the fiber sand not throw any onto the floor. Our Bona Trailer realyl has the best suction so with a less of a vacuum I can only imagine how much improved this setup would be.
I would fully suggest this setup for any contractor who wants to be dustless but is having fiber issues on the floor. While some hardwoods and grit’s didnt seem to produce as many fibers, it is nice to have a solution for all girts and hardwoods. I would give this addon to the Hummel a great rating as it has solved our issues. below is a video of the machine in action. The floor is a hickory floor which usually produces the most amount of fibers and as you can see there is nothing left on the floor.
