In some cases this may be the most effective solution, but in order to get the collecyion out of it, you have to use a high quality filter, and you have to get great collection at dust collection funnel 0.93 source.

They are a great idea for improving the shop vacuum, but don't replace a dust collector connected directly to dust-producing machines. They are good at clean-up of large and medium dust, but are not generally good at capturing the really fine dust.

Some of the shop vacs have expensive HEPA filters that collect the harmful fine dust, but using the disposable HEPA filters for every day cleaning becomes expensive - the add-on cyclone approach may dramatically extend the life of the HEPA filter bags, making this a good approach. Yes, I am guilty. I couldn't bear the thought of spending enough to get a cyclone, so I bought a conventional dust collector.

The kind with a couple bags. The original system had a very good airflow, but I finally figured out why The corner of the shop with the dust collector was being caked with a layer of dust. And with a lot of dust that I could see, it was also mixing the fine dust that I couldn't see into the air for me to breathe.

The first fix was to get 0. The vendor insisted that I wouldn't have enough airflow unless I had those bags on both the top and bottom, so I installed two. System worked great for a few minutes, but then the bags plugged. The chips and dust embedded in the lower bag, and fine dust plugged the upper bag.

Lets see, woodworking for 15 minutes, then 30 minutes with a shop vac, working in a cloud of dust, trying to clean the bags enough so that they could be used again for another minutes.

Didn't make sense. The custom bag they made for my 2 hp collector is about 3 feet in diameter, and reaches my 10 foot ceiling. The bottom bag could be plastic - the air would exit through the top bag, and the accumulated chips and dust from the top would drop in the bottom bag. The performance of the large felt-like bag depends on the "cake" of fine dust on the inside of the bag, providing the fine filtering. Therefore a big bag is required to provide adequate air flow through the cake and felt.

It was a big improvement, but not the final answer. Another solution looked good, but I haven't tried A bar is often included, to knock the dust off the pleats inside the filter, but that puts substantial wear on the relatively expensive filter cartridge. Breaking news - if a baffle is installed to keep the chips away from the cartridge, like the Thein separator described below, that helps the life of the cartridge. I also learned that banging the top of the cartridge, where there are no pleats, may jar more grunge out of the filter than the paddle some systems provide to bang on the inside of the cartridge pleats.

A couple other problems with a single stage collector. First, the dust and chips go through the fan. Better hope you don't pick up a nail or screw and certainly don't use the optional "floor sweep" , because that metal piece can cause a spark when it is hit by the fan, and that spark can smolder in the dust for hours before catching fire in the middle of the night. Second, the air and grunge are blown into the filters before they drop This is sometimes called a two stage dust collector.

A high volume of fast moving air can carry heavy chips in addition to fine Dust Collection Funnel 91 dust. Air from the machines is spun around a funnel-like "Cyclone", and as the air spins around and down the gradually narrower tube, it slows, dropping the dust and chips into a bin below the first stage. With a perfect cyclone, the air stops at the instant it changes direction from around and down, to being sucked up the center, through the fan, and out.

If it stops completely, all the dust is dropped. If it just slows, the chips plus most of the dust is dropped. If there is an air leak at the bottom of the cyclone often at the seal of the trash bin the airflow is disturbed and a lot of dust remains in the air. Note that normally most of the debris is gone before it goes through the fan and into the filter.

The filter after the fan is typically a large, very fine filter, often a pleated cartridge the second stage. However, with little dust left in the airflow, there is little contamination of the filters, so the filters remain very efficient. If you have a cyclone and the filter gets plugged frequently, something is wrong with your setup - likely an air leak at the collection bin, or you should contact the vendor.

There are huge battles about different types of cyclones. Almost any circular container will drop the chips and "look good" but a slight turbulence in the air Dust Collection Funnel Data from a less than perfect shape or air leak, and the efficiency plummets - the fine dust is not dropped. The fairly tall cyclones that do the best job of dropping dust and chips don't fit within the typical small shop ceiling.

Shorter cyclones either require much higher power or become less efficient - don't separate the dangerous fine dust. Bill Pentz designed a cyclone for optimum performance and published the plans on his web site to allow woodworkers to freely no royalty build one for their personal, non commercial, use.

Parts of the design were stolen by vendors who didn't pay design royalties required for commercial use , and other parts should have been stolen - Bill can demonstrate that many of the highly regarded cyclones aren't very good at separating the very fine dangerous but invisible dust. Experts who are not trying to sell a competing product generally agree that Bill's design is excellent.

ClearVue Cyclones is the only vendor currently licensed to use Bill's design in a commercially available cyclone. The ClearVue founder, Ed Morgano, retired, and when he stopped taking orders on May 1, , I feared the death of a good company.

A couple months later July it was bought by Bushey Enterprises, three brothers, who moved the manufacturing to Seattle, with office operations in Burlington Vermont. In August manufacturing is moving back to South Carolina. Wherever they are, the business is continuing. What cyclone to buy? I have heard at least as many bad comments as good about JDS dust collectors. Penn State Industries sells the Tempest dust collectors, but they don't design and build them. Grizzly specs look good, but the user enthusiasm on the woodworking forums is not convincing - Grizzly cyclone users are happy but far less enthusiastic than users of some of the other Grizzly machines.

Shop Fox is a close corporate relative of Grizzly. ClearVue user reviews are always positive. Oneida seems to have good user reviews. All these notes are based on second-hand discussions, not on first person experience. I helped a friend with a commercial shop select and install an Oneida system.

He was very complementary about this web page until I got to the point of recommending Oneida. Bill said "Please rethink that recommendation. I think the Oneida Air System cyclones are probably the worst choice that someone can make today due to terrible separation, poor filtering and way too little airflow in all but their 5 hp and larger units. She was very complementary about this web page and the need for dust collection at the source. She goes on to say "I am sorry to see that you have given a forum to Bill Pentz and his anti-Oneida rhetoric.

I would ask that you remove his negative comments and understand that he has no foundation for them. Trying to understand the battle, I have done some more research Despite the clean appearance, he ended up hospitalized with lung and heart damage that was traced to shop dust, bad enough to require full time oxygen.

As a professor he started researching the problem as a one-time professor, I know that is a very natural thing to do. He became an expert and found most commercial designs didn't hit the target. He offered consulting services to vendors, and testing services to magazines.
