Festool Junkie Blog

Mr. David McGibbon from Festool recently published an article for the SysNotes newsletter from Festool. Air quality is important. You are what you breathe???? I suppose that may be somewhat of the case. With the Festool System, dust and particles are taken out of the game right at the source…the tool.

Not only do the Festool Tools provide accurate and precise work methods, they also provide for an environment that is much more friendly than what most of us that do workworking, solid-surface, floor finishing, and general fabrication are used to.

The paper used for dust collection may not seem like a big deal, however, you should read this article! Thanks David for your “always on”, helpful and cheerful attitude, and your knowledge of these truly remarkable tools.

Festool CT Dust Extractors filter dust in different stages. The first level of filtration is the filter bag. The filter bag has to fulfill very demanding duties: It has to hold back as much dust as possible (goal is 99.9%) and at the same time it has to let the air pass to create the suction. Preventing clogging in the pores of the bag is also important ensuring adequate air flow until the bag is full. The bag needs to prevent as much dust as possible from reaching the final filtration step, the main filter. The less the main filter has to filter, the longer it is going to last and the better job it can do.
The bag has to be tear proof, needs to sit secure in the dust extractor with secure connection between the bag and the dust extractor, the glued joints have to last and have to be dust proof. The bag needs reinforcements at spots with high stress. At the same time the filter bag has to have an acceptable selling price.
Does all that sound like an ordinary paper bag?
Quite a demanding job! An ordinary paper bag couldn’t do it. The Festool CT filter bags are a complex system of paper layers. It took a significant amount of time in the laboratory to develop the right bag for the CT. The engineers examined how dust flows into the bag and how maximum filtration can be achieved. They also have to prevent phenomena like the “dust cake”. In certain dust extractors the dust accumulates to a certain spot and creates a “dust cake”, a very hard piece of dust sitting in the dust bag opposite the inlet, causing the bag to tear.
There are countless hours that went into the design of the filter bag for a good reason: Proper dust extraction only works with the right filter bag.

What are the benefits of the Festool Filter Bag?
” Save Money. Main filter does not clog too fast and does not have to be replaced constantly.
” Save Time. Easy and fast way to dump the dust. Clean way to dump the dust, no clean-up.
” Healthier Work Environment. Less dust in the air.
” Longer Tool Life. Better protection for the vacuum motor in case the main filter is leaking.

Thanks again David, Talk to you soon I’m sure. I wouldn’t want you to become a “Maytag” guy!
