Okay, I made this lovely Thien baffle for my new HF dust collector.
and my plan was to vent it to the outside, I’ve read that’s the best thing to do, especially since the HF filter bag is only good for 5 micron particles, and from what I’ve read, the most dangerous ones are in the 2-3 micron range. So I thought that if I built a cover to replace the top filter, installed a 4” port in it, that I could vent the overflow outside and there would be NO dust in the shop from the dust collector. This is what it looks like.
Here’s the problem, ( and I bet some of you are already hootin’ about what you see here ) the air pressure coming from the impeller is so powerful that I’m afraid that even if I screwed this cover in and sealed it up, that it might not hold, and that furthermore, the back pressure might damage the motor. It’s so strong that if I start the thing up and try to hold the cover down, I can’t get it down into the cannister, it’s like a hovercraft or something.
I know that people vent these things to the outside, but I’m confused as to how that can be done if the air pressure is too great to direct the flow.
Any ideas or insights will be greatly appreciated.
