Want to improve your dust collector's efficiency? Take a look at the filters! In this episode we talk about what kind of filters are best, and why- then we build a "manometer" to tell us when our filters need cleaning. (You can skip to the 8:00 mark for the manometer build details)

Mr. S. Nubs. I cut all the lumber for the "Multi-Function Router Lift" project yesterday. I couldn't help but laugh when you gave the measurement of 3 4/8" for the Upper lead screw block. I have never seen a mathematical joke before, but knowing your sense of humor I realized your wit within the instruction. Brave Mr. Nubs, bravo.
Great video Stumpy and a service to the woodworking community.
Stumpy, the best throughput for a dust collector is no filter at all. I went the HF dust collector, then added a second bag and realized just how much through put I was losing, even with the second bag. Soooooooo, I put in a cyclone, and ported the out put of the cyclone out of the shop and into a small "out house" (complete with the half moon on the door.) I had the output pipe blowing into a 30gal can with a burlap cover, and realized that even that was robbing me of CFM. So now the pipe merely dumps into the building, which also conveniently serves to tell me when the chip bin is full by blowing chips out under the door of the out house.
Yes, that is true. But not everybody can do that.
Stumpy Nubs I know, but for those who can, it is an excellent option, and one that is almost never mentioned.
Thanks for your creative solutions on behalf of the non professional woodworker.
Thanks for taking the time to entertain, err educate me about the manometer. I see me building one of these. Gotta get the most outta my HF 2HP DC!!!
Will you be building a Man-O-Meter, in the near future???
One of these days I will be able to afford a dust collection system, and will put this video to use.
What a great idea, I have a similar indicator on the radon stack, but never thought about using one to indicator the efficiency (or cloggyness?) of the dust collector. Of course, I am still using one of those 5 micron bags, trying to decide weather to upgrade the filter, or simply upgrade the unit (1 hp) to a new one (2+hp) with filter. Tks again!
Hey Stumpy, great video! You should be able to put the manometer anywhere in the shop. Because your measuring air with an open ended manometer, any distance effects should be very very small. It would be good to get it off of your filter, because you're blocking some of that surface area you made by going to filters.
Very cool idea, might have to borrow this one from you....thanks Stumpy.
Another way to prevent evaporation is to put a drop of oil to float on top of both ends of the tube.
Thanks for the info Stumpy, I've been wanting to upgrade mine for some time. Every time I turn it on and see that huge puff of dust coming from the bag I cringe. Always wondered about when to clean the pleated filter and didn't know they could be stacked. Mike
Stacking depends on the filter style. They have to be open on both ends. Single stage collectors with bag filters don't need a stack, just a single cartridge is 8X more surface area.
Enjoyable videos. Thank you. However, if you want to use the camera side shots to add variety for the viewer, then it would be a good idea to look at the side camera during those scenes. It would not be too terribly difficult to switch your position from time to time, then, when editing, you can use the appropriated scenes for a more pleasant viewing experience.
Hey! Who forgot to put a cold one on the bench for Stumpy??!! They oughta be flogged! Whoever is responsible -- Don't Let It Happen Again!! lol
Sooo...if I have an HF DC that is outside and under my house that I have plumbed through to my cyclone separator inside my shop - is is better to remove the lousy filter bag altogether and just let any fine stuff blow free (I really don't care given it is outside and under my house)? Sounds like just having the stock filter bag on there restricts performance? And btw - so far after a couple of months of use - nothing has even reached the DC (as far as I can tell) - it all gets trapped in the Super Dust Deputy. So very little will ever blow outside out of the DC. Thoughts?
Yes, I'd take off the filter bag.
Related question, I have a cyclone and a cartridge filter. But how do I clean the cartridge filter? Cleaning the old bag was pretty easy, if messy. But cleaning the cartridge escapes me, I have paddle beater on it which helps somewhat but there is a still a lot of dust stuck in there.
It depends on the filter. The ones we use from Wynn Environmental are cleaned by simply spraying compressed air on the outside. It blows all the embedded dust into the collection bag (on a single stage unit) or into the lower tray (on a cyclone), which you can then empty.
Ok thanks, I'll try giving that a go on the next rainy day :)
You want to be careful when you clean the filters, you don't want to breath in all of that dust you spent so much effort keeping out of the shop. Most particles less than 10 microns will stay suspended in the air for a long time. To give you an idea, the size of particles that make up smoke from a candle are about 0.2-10 microns.
I'm going to try and do it outside on a rainy day and wear a mask.
caskwith If you are blowing from the outside of the filter you shouldn't have to take it outside. All the dust will go inside the filter and drop into the bag below.
Cutting a hole in a duct or other place with speedy airflow is a bad idea due to bernoulli effect siphoning; you need airflow to be as slow as possible to measure pressure adequately.
So this otherwise great video needs some annotation.
Don't measure pressure around a curve, it doesn't work. You need to measure pressure on a straight section of pipe. Also, I'd recommend using an oil rather than alcohol or water. It won't evaporate quickly.
If you Google "manometer" you will see quite a lot of commercial versions with a bend. In this case, oil wouldn't work either as it would be heavier and less able to react to the low pressure of the dust collector.
I was talking about where you connected it, not the meter itself. It doesn't need to be "instant" either.
Nicholas Smerk It may appear to be connected to a curve, but it is actually connected before the curve, directly in line with the impeller.
Cool. If you measure at the curve, the way the air, or liquid flows will cause the reading to be off or not existent. I've had engineers jimmy rig stuff...ugh enough said.
Nicholas Smerk Like I said, there is no curve where it is mounted, and the curve in the tube is not an issue with this design. But I appreciate the info!
Did you get all metric up in this hut...
Is that English?
@@StumpyNubs Well since it is my second language my guess is my joking skills isnt perfected just yet :) Thank you for a great vid and an awesome chanel. I have a dewalt one stage that I am thinking of upgrading to a 2stage with a filter instead of the bag. One thing i have been thinking about (no troll) Is there a difference between clockwise and not clockwise cyclones? (thinking about how water drains in tub.) /d
How can I upgrade my filter bag, its the type that hangs on the wall. Rocklers Dust Right system. Does anyone make a filter for this type of collector?
Email Wynn Environmental and tell them I sent you. They will give you all the free info you need and if you decide to upgrade, theirs are the best filters I have found. sales@wynnenv.com
Hi Stumpy - Love your work and channel.
I wanted to ask a question as I am still rather new to woodworking and I am also in the process of setting up my shop.
I have a Rockler wall-mounted dust collector that I have mounted in a closet and it is attached to a dust collection bin and ultimately vented outside my shop.
As the unit does not use a filter, is there any means that you can recommend for me to ensure that i am gaining maximum performance on airflow?
Thank you for your time.
The Rockler collector is under powered, so the most important thing is to only hook it to one machine at a time and keep it close to the machine you are using. That means no duct work running to multiple machines.I would mount it in a central location and use their DustRight hose to connect to whatever machine I am using. That hose stretches only as long as needed for each hookup, so it helps with airflow. I don't think it would be worth the expense. Use it as is and upgrade down the road once you've gotten the tools you need first.
Stumpy Nubs Thank you sir - Much appreciated.
very clever
Everyone is worried about the semantics of what item is called what and where things should be mounted; all I can do is wonder which previous decade that shirt came from. I'm guessing the 90's.

Stumpy Nubs, you sir are well versed in all the important subjects!
References to the handicapped and nagging women is degrading. My comments are to be respectful, but these comments from you are not. Your channel is good and has one of my favorites. Please be reminded that small things like microns, a degree in a bevel, a dust nib, and a prejudiced word can make all the difference....and compound errors make a spoiled project.
... A manomeneter measures air pressure not flow. Think you need a form of anemometer.
I said when the airflow is restricted by the filter it builds up PRESSURE which can be measured by the manometer. The meter is not intended to measure AIRFLOW, just the pressure changes caused by the filter as it clogs.
Stumpy Nubs
Stumpy Can you convert the bag type dust collector to a filter. How many times can you clean a filter before you need to replace it. How do you clean the filters?
Mana Mana.. Do doooo.. Do do dooooo.
Dust filter
Love the video! If you're looking for a ready to go solution, check out our differential pressure gauges. They are just like a manometer, but display the pressure on an easy to ready dial. See here: differentialpressure.com/differential-pressure-gauge-overview/600dgc-differential-pressure-gauge/
