The Dust Boy can be run at either volts or volts. From my lathe, to my jointer. This is the dust collection system I use in my small garage workshop. The longer the cyclonic chamber, the greater its effectiveness at slowing down and separating large particles. More horsepower Dust Collection Systems For Woodworking Shops Pdf does mean more noise; both registered 85 decibels at 8 ft.

At 82 decibels measured at 8 ft. 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 upward.

A filter bag hangs off to one side and collects Small Shop Dust Collection System Editor 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 separating 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. Debris entering a single-stage collector passes through the impeller, many of which are made of steel.

Even a small bit of metal, such as a screw, can cause a spark when it hits a steel impeller. Dust-collector explosions are rare, but the potential is there. Debris, metal or otherwise, not only makes a racket when it hits an impeller but also imparts stress on the bearing and will shorten its life.

One way to reduce the risk of fire is to choose a single-stage collector with a plastic or aluminum impeller. Steel impellers are fine, however, if you avoid using the dust collector to sweep up miscellaneous debris off the floor or workbench.

I also used the 1-hp collector with a PVC duct system 4-in. At that distance, because of increased resistance, the air volume drops to under cfm, less than recommended for woodworking tools. In reality, however, one can live with that. When I hooked up the 1-hp collector to a newly installed metal duct system, with my tools in the same configuration as before, I was really surprised. The air volume was back up to 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 , and I measured almost cfm. Hooked up to a 6-ft. Cyclones and two-stage collectors have slightly more internal air resistance; hence the lower cfm reading. Performance ranged from good to so-so, depending 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. A two-stage unit such as the Oneida costs almost twice as much. Penn State Industries also sells a cyclone collector. With two blast gates open, the air volume dropped and was insufficient to operate two big machines at once. More horsepower does mean more noise; both registered 85 decibels at 8 ft. The Delta comes wired for volts but can be switched over to 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. When I connected the 2-hp units to the PVC duct system, they too were robbed of considerable power, but one machine could be operated at a time with satisfactory results.

When connected to a metal duct system, the Jet collector really moved a lot of air, cfm at the tablesaw-jointer connection after about 25 ft. With two blast gates open, the air volume was reduced to less than cfm, still acceptable for some operations.

The Dust Boy produced slightly 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 dust collectors. They cost more, however. Most 2-hp collectors come wired for volts. The Dust Boy can be run at either volts or Garage Shop Dust Collection System Limited volts. 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 the area around it.

The Oneida cyclone, outfitted 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. The Dust Boy as does the Oneida comes with a Leeson motor and cast-aluminum housing and impeller fan , and the sturdy plastic barrel holds a lot of debris, 55 gal. 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. The lower bag must be wrapped around the metal waist of the machine 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.

The skirt and a standard gal. I just wish the skirt were made of felt rather than the more porous woven fabric. This setup will reduce the air volume. When an ad says a collector is rated at 1, 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 pressure, 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 velocity and volume. Many manufacturers rate their machines without bags or duct attached. Your dust collector is only as good as your filter.

I recommend getting a 1 micron filter. This is usually not the standard filter, standard is 30 microns. The 30 micron filter will filter out most of the dense stuff, but will spew out the fine dust particles into t e air.

Since your garage may most likely be attached to your house you definitely want to collect as much dust as possible. Lastly, once you have purchased a suitable dust collector, you will need to run the duct-work to each of your machines.

PVC is not a suitable material to use as static buildup may cause a spark that will explode the fine dust particles. You need to metal piping. Overall, a good dust collector is as much about convenience as it is safety. Less dust in the air is easier on your lungs so you can enjoy life longer.

It also helps keep airborne dust down in your shop which is a plus when it comes time to apply finishes. The lowest price point is not necessarily the place to start at when looking for a dust collector. Nor do you have to shell out the big bucks for a central dust collection system.
