Here's an idea for handling the floor sanding dust volume. My instinct is that the Festool dust collector should be kept for more typical woodworking projects, but you can adapt this idea to a Festool dust collector if you want to keep much of the dust from the Festool collector.
Here are four options:
- Get a Rigid 16 gallon wet/dry vacuum from Home Depot for $99 and connect a Festool Anti Static hose connected to your tool. Or use a 2 inch line connected to it and the tool. (Read on, because this option will clog your Rigid canister filter rapidly);
- Put a cyclone dust collection top in between the vacuum and the tool with a garbage can or drum to catch most of the dust. See
http://www.leevalleytools.com for various cyclone tops in 2 inch or 4 inch sizes. Use a metal garbage can under the cyclone top, not a plastic can which can't handle the vacuum/air pressure without collapsing. (Ask me how I know that.) Lee Valley has I think two sizes of cyclone top for different size garbage cans/drums, in clear and black, in addition to the 2inch/4inch options.
- Put the Festool dust collector in place of the Rigid vacuum;
- Put a portable dust collector with 4 inch ports in place of the Rigid vacuum.
The trick is to pick the right cyclone lid for your needs.
So why do I say go with a Rigid vacuum and a cyclone lid? Fairly quiet and powerful vac, very well made cyclone lid. When faced with replacing three hundred pounds of wet sand in my pool filter with new filter media, I connected the Rigid vacuum with a 2 inch hose to a cyclone lid from Lee Valley Tools, which in turn connected to a two inch vac hose. I kept the sand covered with water in the filter from a garden hose, agitated the sand/water as I vacuumed it out, and every bit of the water and sand went into the cyclone/garbage can, none in the vacuum. No problem. Why not tip the filter to clean it out? It would have broken the filter elements inside the filter.
I have several Festool tools, but no Festool dust collector. I connect my tools to the Rigid vacuum which has been adequate for my needs. I've needed to put my money in tools for specific projects and a CTS is a stretch for me to justify. The TS55 sometimes blows dust that is not collected and I suspect a CTS would do a better job. The Rotex has most of the dust picked up just fine with the Rigid vacuum. The anti static Festool hose plugs right into the 2 inch port of the vac.
One last word in favor of the CTS - One of the great values of Festool sanders is in preserving the life of the sanding pads (and reducing heat?) by using efficient dust collection. If you make your money, in part, with sanding, get a CTS with adjustable air flow, not a Rigid vacuum. I'm a part time cabinet maker/wood worker, so it makes sense for me. It also makes sense to me not to connect a floor sander to a CTS, but I don't own either one.
