Dépoussiéreur, j'ai lu Bill Pentz...

Suite à ce que propose plusieurs membres, je viens de passer 2-3 heures à lire le site de Pentz puisque je veux m'acheter un nouveau dépoussiéreur et c'est assez alarmant ce qu'il raconte:

-Pratiquement aucun dépoussiéreur ou cyclone n'enlève 100% de la poussière de moins de 1 ou 2 microns
-La très fine poussière est vraiment dangereuse pour la santé
-l'idéal serait de mettre le dépoussiéreur à l'extérieur mais presque impossible pour tout le monde
-Les dépoussiéreurs avec des sacs filtre sont la pire junk (je possède un ROK de 1hp )
-même les dépoussiéreur avec des filtres solide type cannister sont faits cheaps et les fabriquants mentent sur leurs efficacité
-Les fabriquants/vendeurs boost les cfm de leurs machines alors que en vérité il faut divisé au moins par 2 les chiffres réels
-Les dépoussiéreur de types cyclone sont peu performants, 1/3 moins, tellement ils doivent tirer de l'air à cause du cyclone qu'ils sont incapables de tirer toute la poussière à la source contrairement à un dépoussiéreur avec filtre cannister ça prend donc un dépoussiéreur cyclone d'au moins 3.5hp
-Ça prend absolument une fan qui envoi de l'air vers l'extérieur avec un bon courant d'air si on travail à l'intérieur (je l'ai)
-Et j'en passe je pourrais écrire pendant longtemps...

Bref pour mon cas à moi, vu que j'ai une petite shop je branche une machine à la fois, il dit que un dépoussiéreur de 1.5hp avec une fan de 11'' est suffisant ou plus.

Il dit que les séparateurs de poussière (comme oneida ou clearvue) sont essentiels pour éviter que les gros copeaux ne viennent endommagé le filtre à l'intérieur mais ailleurs sur sont site il dit que ça restreint grandement le succion?
La je ne comprend pas? Les cyclones tirent moins mais si on prend un dépoussiéreur on doit ajouter un séparateur de poussière type cyclone pour aider?

Je voulais aller acheter le dépoussiéreur Craftex 1700cfm 2hp avec cartouche sur le dessus en spécial à 599$ mais là je sais plus. Dois-je ajouter un cyclone oneida avec port de 4'' ou non? ca vaut la peine?

merci de m'aider

il y a en fait au moins une vingtaine d'article sur Fine woodworking.

entre autres une discussion interressante sur les systèmes d'aspiration d'air ambiant...

probablement qu'il y a des mortaiseux qui on un système efficace mais malgré le fait que je peut envoyer a l'extérieur ce que je produit il y a un outil pour lequel je n'ai toujours pas trouver une solution c'est ma scie saw stop. J'ai acheté le guide autour de la lame avec la sortie d'aspirateur et c'est pas du tout efficace. J'ai essayé le système avec un bras excalibur (a mon travail) et là aussi pas satisfaisant. Je réussit a aspirer dans le cabinet mais il y a tjrs une pourssière fine autour de la lame.

Si tu relies bien le site de Bill Pentz il recommande les cyclones avec des filtreurs a cartouche de qualité avec beaucoup de pieds carrés de surface style Wynn.

Wynn n'expédie pas au Canada mais tu peux acheté leur cartouche chez Stockroom Supply au Canada

C'est quoi ton nom d'usager et mot de passe pour Fine Woodworking?

Le lien de l'article amène sur un site qui le demande....

C'est pas un document pdf.

pourtant le titre a bien pdf a la fin....

quant j'ai essayé de le mettre en fichier, on me dis que je ne peut pas mettre des dossiers pdf en dossiers joints....
je vais essayé autre chose.

quant j'ai écris qu'il y avais un débats sur les filtreurs je n'avais pas lu le commentaire de Norinox (parti pendant que j'écrivais le mien)

le débat c'est que pour certain spécialistes ces filtres peuvent causer plus de mal que de bien si il sont mal situé en aspirant l'air et la poussière vers l'usager. Donc il faut réfléchir au chemin entre le filtre et la source et s'assurer que l'on est pas entre les deux.... J'en mettrais un si je travaillas dans la cave chez moi mais c'est pas vraiment une solution.

Dust Collection for the One-Man Shop
How to get the most performance from 1-hp to 2-hp
dust collectors
BY ANATOLE BURKIN
Don't throw away the broom just yet. Even the best dust-collection system won't eliminate the need
for occasional sweeping. A good system, however, will keep the broom and your lungs from wearing out prematurely.
There are two main points to consider when choosing a dust collector. First, fig- ure out the air-volume requirements of the machines in your shop (see the chart on p. 84). Next, decide on what kind of hookups you are going to use: flexible hose, PVC pipe or metal duct.
To see what size and type of collector would best suit a one-man shop, I gathered a sampling of machines, from 1-hp single- stage units to 2-hp two-stage collectors, in- cluding one cyclone: Delta (1 hp single stage), Dust Boy (2 hp two stage), Jet (2 hp single stage), Oneida (1 hp cyclone) and SECO UFO-90 (1 hp single stage). I used the collectors with my tools, which include a 10-in. cabinet saw, a 15-in. planer, an 8-in. jointer and a 16-in. bandsaw.
The horsepower rating is a fairly reliable guide to the performance of a dust collec- tor (see the chart on p. 85). Hookups, how- ever, are everything. Too much flexible hose will rob even a big collector of pow- er. PVC pipes, in short runs, work fine with a sufficiently powered collector, 1 hp or more. Metal duct, not unexpectedly, per- forms best. Even an 8-year-old, 1-hp col-

lector can collect chips from machines 25 ft. away when hooked up to a properly designed system. Using a 1-hp collector this way may seem misguided, like putting a racing exhaust system on a subcompact car, but the experiment illustrates how you don't have to spend a fortune to get decent results. Every shop is different, of course, and your results may vary, so use my find- ings as guidelines, not absolutes.
A 1-hp single-stage collector
can handle any machine in my shop The biggest sawdust producer in my shop is a 15-in. planer. And even a 1-hp single- stage dust collector can handle that ma- chine, hooked up with about 6 ft. of 4-in.-dia. flexible hose. I borrowed a new UFO-90, same as my old collector, to see if anything had been changed. It's still the
Three styles of dust collectors
The most economical and biggest-selling dust collectors are the two-bag, single-stage models. Single stage means the dust is sucked through the impeller (fan) and dumped into the lower bag. The upper bag collects fine sawdust and lets the exhaust air back into the shop.
Two-stage collectors are the next step up. The motor and impeller sit atop a barrel. Chips enter the barrel and are directed downward, although the swirling air inside may occasionally move smaller chips up- ward. A filter bag hangs off to one side and collects the finest dust.
Two-stage cyclones are at the top of the evolutionary chain. The motor and impeller sit atop a cone-shaped canister, the cyclone, which is connected to a trash can below. Chips or other large debris enter the cyclone and swirl downward, avoiding the impeller. The longer the cyclonic chamber, the greater its effectiveness at slowing down and sepa- rating large particles. Air is filtered either by a pleated internal cartridge or by one or more felt bags hanging off to the side of the machine. Internal-cartridge cyclones use the least amount of floor space. The upper bags or cartridge filters of all collectors must be
shaken out occasionally to remove fine dust.
DANGERS OF SINGLE-STAGE COLLECTORS Debris entering a single-stage collector passes through the impeller, many of which aremadeofsteel.Evenasmallbitofmetal, such as a screw, can cause a spark when it hits a steel impeller. Dust-collector explo- sions are rare, but the potential is there. De- bris, metal or otherwise, not only makes a racket when it hits an impeller but also im- parts stress on the bearing and will shorten its life. I heard of a woodworker whose col- lector's sheet-metal housing was punctured by a screw that entered the impeller.
One way to reduce the risk of fire is to choose a single-stage collector with a plas- tic or aluminum impeller. Although the im- peller itself won't cause a spark, metal de- bris striking the steel housing may have the same effect. Steel impellers are fine, howev- er, if you avoid using the dust collector to sweep up miscellaneous debris off the floor or workbench.
SINGLE STAGE
Sawdust must first pass through the impeller (fan) before being separated.
BARREL-STYLE TWO STAGE
The larger chips entering a two-stage collector tend to drop out before they have a chance to strike the impeller.
Small, portable collec-
tors are easy to move around the shop. Make connections to
one tool at a time using a short piece of flexible hose.
same machine, rated at 650 cu. ft. per minute (cfm) by the manufacturer, but when hooked up to 6 ft. of flexible hose, it moves about 420 cfm. That's slightly less than the 500 cfm recommended for a 15-in. planer, but 90% of the time the 1-hp collec- tor can handle it because I rarely plane 15-in.-wide stock.
One-hp single-stage collectors cost about $200. Some woodworkers buy two units and station them strategically in their shop. At 82 decibels (measured at 8 ft.), a 1-hp dust collector isn't much noisier than a vac- uum cleaner, and each one takes up about 3 sq. ft. of shop space.
I also used the 1-hp collector with a PVC duct system (4-in.-dia. pipe and fittings) and measured the moving air volume at the tablesaw-jointer connection, which is
TWO-STAGE CYCLONE
The shape of a cyclone is most efficient at slowing down the speed of debris, allowing most of it to settle out before reaching the filter.

at the end of about 25 ft. of pipe and hose. At that distance, because of increased re- sistance, the air volume drops to under 300 cfm, less than recommended for wood- working tools. In reality, however, one can live with that. But if I'm face-jointing wide boards, the collector can't always handle the volume, and chips jam the jointer's dust port. Maybe 80% of the time it works okay.
When I hooked up the 1-hp collector to a newly installed metal duct system, with my tools in the same configuration as be- fore, I was really surprised. The air volume was back up to 360 cfm, very acceptable. Then I hooked up my old 1-hp collector, which is outfitted with oversized felt bags (available from Oneida Air Systems) that improve airflow and capture fine dust (see
the story below), and I measured almost 400 cfm. That's a significant gain.
A hp collector can be hooked up to longer runs of hose or duct

not have any trouble removing chips, even with a long (12-ft.) run of hose. Delta rates its hp collector at 1,200 cfm, a number that is derived in a lab, not under real shop conditions (for more on manufacturer specs, see the story on the facing page). Hooked up to a 6-ft. run of 4-in.-dia. flexi- ble hose, I measured about 500 cfm with the Delta and 470 cfm using an Oneida Air Systems hp cyclone collector. Cyclones and two-stage collectors have slightly more internal air resistance; hence the low- er cfm reading. That's about what you can expect from any hp collector hooked
up to 4-in.-dia. hose.
I also hooked up the hp collectors to
two machines running simultaneously. Per- formance ranged from good to so-so, de- pending on how much sawdust was being spit out by my tools. The best way to direct maximum airflow to the tool being used is to attach a blast gate to each hose.
Hooked up to a PVC duct system (a run of about 25 ft. of pipe), both the Delta and Oneida collectors captured most of the sawdust when running one tool.
A hp Delta collector costs about $350. A two-stage unit such as the Oneida costs almost twice as much. Penn State Indus- tries also sells a cyclone collector. (For more on the advantages of two-stage col- lectors vs. single-stage units, see the story on p. 83.)
Both hp collectors performed excep- tionally well when connected to metal duct and used with one tool at a time. With two blast gates open, the air volume dropped and was insufficient to operate two big ma- chines at once.
The larger-volume bags or canisters of hp collectors hold a lot of material, about 30 gal. worth, which means fewer trips to the compost pile, a big advantage over the 1-hp machines that hold about
Measurements were taken with a dial-gauge manometer (a pressure gauge) and pitot tube. The chart at right compares the performance of a few dust collectors when using hose, PVC pipe and metal duct.

There's a fair amount of misleading marketing specs on dust collectors. When an ad says a collector is rated at 1,200 cfm, what does it mean? Not much, really. Cfm stands for cubic feet per minute, a measure of the volume of air moving past a point of reference. The cfm figure needs to be put in the context of the amount of resistance, or friction, present (called static pres- sure, or SP). Air moving through duct or hose encounters resistance, just as a person would slipping down a water slide. The more bends and bumps, the slower the ride or the lower the air ve- locity and volume. Many manufactur- ers rate their machines without bags or duct attached.
While trying out a number of dust collectors, I measured their perfor- mances under real working conditions, using flexible hose, PVC pipe or metal duct in my 420-sq.-ft. shop (see the chart above). The resistance readings ranged from 3 in. to 5 in. I also mea- sured collectors hooked up to a
straight piece of 6-in.-dia. metal duct, just to get a baseline, highest-possible performance figure.
Collectors ranging in size from 1 hp to 2 hp have impellers (fans) sized from 10 in. dia. to 12 in. dia. All things being equal (motor speed and impeller design), a bigger impeller coupled with a bigger motor will move more air than a smaller pairing. There are some dif- ferences among collectors; to learn more, ask a manufacturer for an im- peller performance chart.
As soon as any collector is hooked up in the shop, performance declines in relation to the length and type of hookup. That's why smooth-walled metal duct, with wide-radius elbows and wyes, is better than PVC pipe.
Materials that affect airflow. The met- al elbow (top), which is designed for cen- tral dust-collection systems, has a gentle sweep, which lowers resistance to air- flow. Plastic PVC pipe has a tighter-radius bend and restricts airflow more. Ribbed flexible pipe also disturbs airflow, up to three times as much as metal.

half of that. A hp single-stage collector takesupabout7sq.ft.ofshopspace.Buta vertically stacked two-stage cyclone such as the Oneida takes up only sq. ft. of shop space, a big plus in a small shop. More horsepower does mean more noise; both registered 85 decibels at 8 ft. The Delta comes wired for 115 volts but can be switched over to 230 volts. The Oneida comes without cable or switch. It can be wired to run on either current.
A 2-hp unit can sometimes handle
two machines at once
Hooked up to two 6-ft. runs of 4-in.-dia. hoses, a 2-hp single-stage collector draws over 350 cfm from each port, plenty for many woodworking machines. The 2-hp two-stage Dust Boy didn't match the pow- er of the 2-hp single-stage Jet machine, al- though it has other qualities that may be preferable (see the story on p. 83). When I connected the 2-hp units to the PVC duct system, they too were robbed of consider- able power, but one machine could be op- erated at a time with satisfactory results.
When connected to a metal duct system, the Jet collector really moved a lot of air, 570 cfm at the tablesaw-jointer connection (after about 25 ft. of duct). With two blast gates open, the air volume was reduced to less than 300 cfm, still acceptable for some operations. The Dust Boy produced slight- ly lower readings but still had more than enough power to run one tool at a time in any configuration. If you regularly operate more than one machine simultaneously, it
would be wise to look at 3-hp or bigger dustcollectors.
The 2-hp machines are no noisier than the hp collectors. They cost more, how- ever. The Jet is priced at $400; the Dust Boy sells for about $650. Most 2-hp collectors come wired for 230 volts. The Dust Boy can be run at either 115 volts or 230 volts.
Choosing among the options
On the matter of choosing a dust collector, a two-stage cyclone gets my top vote. A small cyclone collector takes up less room, is easy to empty and runs very clean. For example, on all of the single-stage units, even after running them for only an hour,

fine dust appeared on the machine and in theareaaroundit.That'sbecauseit'sdiffi- cult to get a perfect seal between the bag and housing. The Oneida cyclone, outfit- ted with an internal filter, rubber gaskets and wide metal ring clamps, seals better.
Two-stage units such as the Dust Boy (Delta also makes a two-stage collector) are also nice and compact. The Dust Boy takes up 6 sq. ft. and less vertical space than most collectors. The Dust Boy (as does the Oneida) comes with a Leeson motor and cast-aluminum housing and im- peller (fan), and the sturdy plastic barrel holds a lot of debris, 55 gal. worth. Before it can be emptied, however, the heavy motor and housing must be lifted off.
Removing the lower bag of a single-stage collector is an easy matter of loosening a band clamp. The real fun begins when you try to reattach it. If you've ever had to put your pants on with an arm in a cast, you'll get the idea. The lower bag must be wrapped around the metal waist of the ma- chine and held in place before the clamp can be cinched. Some manufacturers, such as Jet, add an elastic band inside the lower bag to facilitate reattachment somewhat.
Woodworker's Supply tried to solve the lower-bag problem with a clamp-on skirt accessory. The skirt and a standard 30-gal. trash can replace the lower bag. Because the skirt remains attached to the collector's housing, it's easy to cinch the lower belt that attaches the skirt to the trash can. I just wish the skirt were made of felt rather than the more porous woven fabric. This setup
Better connec- tions. The Oneida cyclone collector's trash barrel is con- nected by a large metal ring, which simplifies reattach- ment (left).

branches. The 5-in.-dia. pipes serve the biggest tools (jointer, tablesaw and plan- er), even though they all have 4-in.-dia. dust ports, which ensure good air volume to the machines. Also, you can change the dust port to a 5-in.-dia. connection for bet- ter performance. A 5-in.-dia. to 4-in.-dia. reducer is used to make the transition.
The 4-in.-dia. branches that split off the 5-in.-dia. line serve smaller tools, such as the bandsaw and router table, Blast gates are installed at each tool. The final con- nections were made with flexible hose, which allows me to move my tools around.
I used 24-gauge (mostly) snap-lock pipe, spot-welded fittings and aluminum blast gates, which are available from many companies. (Avoid lighter-gauge metal duct designed for heating or cooling systems; it can collapse under vacuum.)
A higher-quality system will employ 22-gauge spiral pipe and welded fittings, which are stiffer and more airtight,
and yes, they cost more. Quick-Fit
duct supplies from Nordfab are also premium priced, but the components go together easily and don't require duct tape or caulk.
Although individual 24-gauge compo- nents aren't that expensive (a 5-ft. run of 5-in,-dia. snap-lock pipe costs about $8), it all adds up. A very basic three-machine
will reduce the air volume (the collector "breathes" through both bags) when using the stock upper bag. With a larger upper bag, I found that the cfmreadings were not compromised. But if you happen to vacu- um up any offcuts, they will make quite a racket rattling around in a metal trash can.
Although many woodworkers, myself in- cluded, have used PVC drainpipe for duct

without mishap, experts warn against us- ing the material. The connectors (elbows and wyes) restrict airflow, and the material builds up a static charge, which may cause a spark and set off an explosion. (Running grounded copper wire inside the pipe re- duces the hazard.) Use PVC at your own risk. Metal duct and fittings are obviously better and will also last longer. I've broken
because it produces about three times the friction of metal pipe. Friction will reduce the performance of the system. All pipe seams and connections must be sealed with caulk or duct tape. Clear silicone caulk is a good choice because it's virtual- ly invisible and is easy to remove.
DESIGN HELP IS AVAILABLE
Designing the ductwork for a central dust- collection system can involve a lot of cal- culations. For those of us who skipped math class, there's help available.
• Air Handling Systems of Woodbridge, Conn., has an on-line duct calculator pro- gram (www.airhand.com). The company outlines the concepts of duct design in a four-page brochure.
• Oneida Air Systems of Syracuse, N.Y., will design a duct system free of charge for its customers (www.oneida-air.com). All that's required is a shop drawing show- ing the types and locations of woodwork- ing machines.
• Nordfab of Thomasvile, N.C., manu- facturers of the Quick-Fit line of duct and fittings, offers a free design service. The company has a downloadable program (www.nordfab.com), but you need a CAD program to run it. The company also offers a peel-and-stick shop layout kit for analog woodworkers.

Designing a central dust-collection system
Oneida Air Systems designed my ductwork, which is very typical for a one-room shop under 500 sq. ft. The ductwork begins with a 6-in.-dia. pipe connected to the collector. At the first wye
setup may be had for a few hundred dollars. A system for half a dozen tools and a floor sweep may cost $500 or more.
To help illustrate the photos in this article, an orange/black flex hose was used to make connections from pipe to tools; black flex hose, however, works fine. It's best to use a minimum of hose

mettre le cyclone et l'aspirateur dans une pièce (mettre quatre murs autour) avec des filtres hepa dans la porte....

l'aspirateur au plafond est oui fortement critiqué parce que ça enlève la poussière oui mais ca peut pas aspirer suffisamment pendant que tu travailles pour que tu respire moins de poussière. La solution de Norinox de sortir quant tu fais de la coupe intense est aussi ce que je fais. Pendant ce temps je laisse mon système central pour faire évacuer l'air. Probablement un bon aspirateur au plafond avec filtre hepa ferais la même chose.

l'autre approche c'est de n'acheter que des outils (sableuse, scie, toupie,) qui permets d'attacher un boyau a un aspirateur avec des filtres hepa. J'ai du festool.... mais je suis certain que de bon outils (d'autres fabricants) sont efficace avec un bon aspirateur qui part avec l'outil.
