I have a different one, the one from clearvuecyclones, but it's on a
30 gal steel drum. It's then hooked up to a network of 2-1/2" clear
pvc piping with blast gates. What's really fun is if I forgot to open
a gate the flex hosing between the cyclone and the piping shrinks and
it will lift one end of the drum up in the air.

LOL... I have a 20' x 4" hose hose attached to my DC and if I don't need
20' I run the hose up to a hook near the ceiling. Often the hose will hang
about 4 inches above the floor and if I have the DC running the hose will
gently swing around occasionally making contact with the floor. Reminds me
of an elephant's trunk sniffing around for peanuts.

I clean the HEPA filter in the Fein every 3 months or so. Without the
cyclone it would be at least every week.

I have a Festool with dual HEPA filters and I have always used it with a
bag. I do not use a cyclone or other container to catch the debris. The
vac gets it all. I use the vac with my sanders and Domino 95% of the time
and have been using it for almost 3 years. I have yet to clean or even see
any dust on the HEPA filters. Are you using a bag with your Fein or have
you considered doing that along with the cyclone to preserve the HEPA
filters? Also in my case the bags don't seem to cut down on the flow until
they are absolutely "packed" full of debris. Oddly enough I have sanded 3
kitchens plus all of my new bedroom furniture plus numerous other projects
and cut in excess of 2000 mortises with my Domino and I am still only
working on my second 22 liter bag. I checked the bag yesterday and it is
about 25% filled.
