    Bag Style DC Owners - Clean Your Bags

    I have an old 1HP Delta Bag DC that used to take care of my whole shop. I would move it from machine to machine (I am amazed that I used to have the room to do that). It is now dedicated to my jointer.
    I improved the performance by adding an American Fabric Filter bag and converting the lower bag to a solid one. I just stuffed a lawn bag into the cloth lower bag and it’s lasted a decade.

    I was well aware that the filter bag was due for cleaning. The give-away on baggers is that the bags blow up like balloons. I know that the original bags that come with baggers do this somewhat from day one but, that is because they are a fraction of the size they should be. If your bags are taught, they are impeding airflow. They should be semi-soft to the inquiring finger but, I digress . . . . Here's a calculator for surface area to airflow.

    I had avoided cleaning the bag because I just knew it was going to be a monstrous undertaking. In fact the whole process only took about 40 minutes and was pretty easy. The bag used to be so inflated that I could nearly get a “boing” out of it if I smacked it. It now looks like this with the motor running:

    I removed the bag and used some spring clips to hold the opening shut. I shook it from top to bottom, removed the clips and dumped the spoil into the trash. I then turned the bag inside out and vacuumed it with a brush attachment. I turned it right side out, vacuumed again and re-installed the bag. The amount of airflow is dramatically increased. It seems that this little DC has nine lives and is now on number three .

    I tried cleaning my bag once, and she got all upset with me when I forced her into the shower. Never again. Took weeks for the swelling in my face to go down.

    Before I got my Wynn filter even when my HF was brand new I remember the filter bag being so taught you could play it like a a drum. I always thought that it was supposed to be like that

    It also helps that she's not Internet savvy and will never see that post.

    No worries...I'm still safe. Because, you know...800 miles.

    Back on topic though, I never realized a filter bag shouldn't be taut like a drum. That's good info to have. I had the same, albeit brief experience with the HF bag as Bob. I ordered my Wynn filter as soon as I got the DC, but I did fire it up with the bag just to see it run and feel the suction.

    I imagine that some back pressure is built into the designs. Now that mine has a nice new coat of "seasoning", it will just fully inflate. The bag does collapse back inward easily if you poke it with your finger whereas before, it was more like a balloon . With the singed felt bag, the filtering is optimal when seasoned. If left too long as I had done, the felt become permeated and if you whack the bag you will actually see a puff of dust escape. I noticed this condition an embarrassingly long time ago and just finally took care of it. The important message is that it was not a big deal like I had feared and the benefits are immediate .
