Dust Collection - help deciding best approach.

[Elaine Fraser]

I have been trying to read about dust collection and I am not sure what I should do based on finances, need and the fact that I don’t have the same selection of DC’s in Vancouver, BC. I have tried to read Bill Pentz’s site and now I’m afraid


I have a 11x20 single car garage. I have a table saw, mitre saw, router and 13” planer. I have just bought 6” pvc pipe for the main line, i will use 4” flex to the tools, these runs will be short. My planner will be on the longest length of flex at the end of the 10’ line, but the fan really blows the chips far (dewalt 735). The main line will be 10’. I am a new hobbyist and I only work on weekends. I attach a shop vac to the sander.


I looked into an Oneida V series 2 HP model, but since it needs to be shipped from the east, the cost is about $3000 cad. That is over my budget. BusyBee has 2hp cyclone on sale for about $1600, this model looks similar to the Laguna and King Industrial models. I’ve heard mixed reviews about this style of cyclone.


There is a Cantek 5 HP dual bag model on Craigslist for $350. I searched to see if anyone has done a mod with a 3 or a 5 hp DC with a XL Super Dust Deputy, but I can’t find anything other than the HF 2 HP mod. Could I get rid of the two bags and filter outside if I add the XL Super Dust Deputy? I’m concerned I may be missing something about airflow and burn out the motor. If I keep the door a jar would that be enough to replace the lost air from filtering outside?


I am concerned about footprint since the double bag, plus the Dust deputy would take up too much room, so I would only be interested in this option if I could make it smaller.


I’m driving myself a bit mad trying to determine the best option at a reasonable cost. I am interested in getting as much of the fine dust as possible which is why i am wondering about the 5 HP model (based on reading Bill Pentz site).


Does anyone have any knowledge or experience converting a 3 or a 5 hp DC? Or should I just go with the BusyBee 2 HP cyclone?


I have thought about buying in the States, but I would need to pay a second tax, and I’m not sure about duty on an Asian import.


thanks in advance.

I set up my shop in '05, with a 2hp woodsucker cyclone. Ended up replacing it with a 3hp last year, and built an outside air dump, with a blast gate so I can use my filter in cold weather. The 3hp is a huge improvement, but 5hp would be better. Cost of good equipment and piping is expensive.

[Andy Giddings]

If budget and space is an issue I would recommend getting a single stage Jet/Delta/Shopfox unit either new or used and modifying with a cyclone/aftermarket filter. Apart from HP, impeller size is going to be important and the HF unit has a smaller impeller. There are plenty of examples where people are using this setup successfully with plenty of suction and excellent filtration. Keep the main duct as big as possible until very close to the tool in question, then use a very short run of flex. Your 4 inch ports are probably going to limit the effective collection so you may want to consider enlarging where possible. Don't set up a complicated duct system with lots of gates and flex as you'll encounter significant pressure drops. A good straight run to a single machine that is switched around to whichever tool you want to use is going to maximize your collection

Hi Elaine,

With a budget in mind, the used Cantek with the XL Super Dust deputy would give you a darn good system.

Elite Tools has the XL SDD for $350 and a 17 gallon container for $150. For the container, you can easily adapt a food grade metal or plastic barrel. They can usually be had for ~ $25.

Both of the above items are oversize and are an additional $50 for shipping.

http://www.clearvuecyclones.com/ has Wynn nano filters but it will be ~ $400 by the time you get one to Canada. If you can exhaust outside, go for it. There will be very little material that escapes the cyclone.

The problem with the short/stubby style cyclones is quite a bit of material makes it into the filter. This means you will need to be vigilant in cleaning the filter regularly and emptying the bag under it.

I did a mod with a BB 2 hp/11" impeller/8 amp motor and get ~ 500 cfm with a 5" main. It is only adequate.

Their current 2 Hp/12 3/4" impeller set up goes on sale for ~ $600. That should give you somewhere around 750 CFM, that would be alright.

The Cantek motor/impeller would be heads and shoulders above either and could even be used as an ambient air filter when doing hand held routing !

I would suggest you run a main pipe the same size as the cyclone inlet and increase all your tool collection ports to at least 5".

Cheers, Don

If the Cantek 5hp was local,I'd have to show some real restraint to not snag it.And we build systems,custom rolled cyclones,impellers,yadayada.

I'd first off,not make any modifications that weren't reversible.Oh,we'd probably roll up a cyclone but,don't completely give up on a good bagger.I would go with more bags,of a smaller diam.Think a bank of 4? 12" or so bags,coming out of a manifold...hugging a wall.Quality bags can be very efficient.Wrap the whole thing in a "house".See what I mean,we'd build something with it.

And yes,venting outside,weather permitting should be on every system if at all possible.

[Don Jarvie]

Give the size of your shop I'd get the Cantek use it as is with the 2 bags. 5 hp will be plently. Then add the 4" flex hose and move it from machine to machine as needed. When you don't need the DC the hose can be stored out of the way.

I did the same thing with a 3 hp Relient. All my machine dust ports are on one side of the shop so this system works.

[Brian Brightwell]

In my shop the cost of my dust collection system is exceeded only by the building itself. However, it is a necessity with large power tools. A wide belt sander will not work without DC.
If I was just starting woodworking I would consider going Neanderthal.

Elaine,
My shop is about the same size and setup as yours. I don't have a TS but I do have a band saw, a lathe and a drill press. The fan on my planer was broken by fragments of a broken board, so I have to use suction to control the dust (chips, mostly) from it. My main dust collector is a Jet DC-1100VX-CK (1.5 HP). I have an inexpensive shop vac dedicated (pretty much) to my router and another that switches between the lathe and the miter saw. The Jet has two inlet ports that I fitted with manual blast gates, It is shared (one at a time) between the lathe, planer and band saw. It provides plenty of CFM and is easy to clean. After two years I have barely begun to fill the first bag.

I am commenting on your question with some reservations, because I think mine is a minority view. I can only report where I came down after some years of studying this subject.

1. To leap right into it, I think that people have unrealistic expectations of cyclones. IMO they are not worth the money or the space if either resource is tight. They do not increase CFM or static pressure, they just cause the larger particles to drop out of the airstream before they get to the filter. That's nice but all it means is that you don't have to clean or change the filter or bag as often. In that perspective cyclones are a luxury for people like us. Get a canister unit with a filter that you can clean easily. If you have 220 volt service, consider a 2HP Jet like the 1200VX-CK1 It might fit your budget.

2. Sanding at the lathe is my major source of dust. The Jet and a shop vac do pretty well.

3. The miscellaneous nuisance dust sources are my biggest problem, especially hand-held routers. My simple PC390 router has no dust port. Next is the miter saw. The hookup to a shop vac gets most of the fines but I still have to sweep up sawdust (fine chips) after every session.

4. Although point-of-source collection is a key strategy, given the above, consider getting an air cleaner that you can hang from the ceiling. I had one in my previous shop and it worked wonderfully at preventing accumulations of fine dust that I had not been able or willing to collect at the source. I don't really have space for one in my present shop, but I am still considering this option.

5. The earlier point about hand tools is a good one. I use planes and card scrapers a lot and their use really cuts down on sanding time and dust.

Best wishes

Whoa!! A 5HP or even 3 for your set up is WAY way too much. A 1 1/2 or 2HP collector will work fine.
I would try to get a cannister filter or vent out side.

Don't bother with ducts. I simple setup like a centrally located collector with 4" flex to your machines will work fine.
The biggest collection issue you have is the planer. The other machines are more difficult to collect I wouldn't stress over them. You will always be doing a lot of clean up by hand around a router or miter saw.

Air filter and respirator or mask or just as important in a space this small.

I think you could have a good set up for around $4-500.

Remember Bill Pentz is all about actual fine particle dust collection, which is both impractical and unnecessary for the hobbyist. Most of us are just trying to keep from getting buried in shavings from planers and jointers. This is why every collector Clear Vue sells is 5HP.

I rely on my respirator and air filter to protect lungs, not a DC.

[Larry Frank]

I think that a 1.5 -5 hp collector with a canister filter would work well in your space. Use it with a single hose to the machine you are using.

I do not agree that fine dust collection is unnecessary....it is really important. The BEST way to control dust is at the source. Once it is in the air it will be on your clothes and hair and everything else and unless you leave your clothes in the shop, you will in your house.

As to a respirator, they work well especially if you have a good one. I do not like using one as it makes breathing more difficult as you get older. I wore one at work for many years so I understand wearing one. At work we were fit tested to make certain they worked properly.

Thanks for mentioning a dust mask. I agree that this is an important part of workshop safety. The effectiveness of a face mask is limited by the fit of the mask and how difficult it is to breathe through it. A good mask will have a flexible margin to fit well against the face, especially over the bridge of the nose, and be adjustable to fit different sizes. It should have a one-way valve to allow easy exhalation and avoid fogging eyewear. It should carry a NIOSH N90 or N95 rating (or Canadian equivalent)

Get the Cantek if it's still available. Build a Thien separator for it and vent outside. You can keep the footprint to the diameter of the barrel you use since you won't have to have space for a filter if you vent outside. A shop that small really doesn't need ductwork, just locate the DC in a central spot and use a short length of flex hose.

[John Lankers]

I think Deb's suggestion is worth considering if your electrical panel can handle it - it would be a heck of a deal.
However, since you're on the "wet" coast I don't know how venting outside would affect the RH in your shop, a dust collector can easily replace the air inside the shop in a matter of minutes.

Grizzly ships to Canada very reasonably priced. They respond to email questions prior to purchase. I went with their 3 hp cyclone and have been incredibly happy. Had an issue with the filter cleaning brush on shipping that they took care of within 2 weeks ( I had the new brush installed on the filter in under two weeks no charges) of me sending pics in an email. The performance has been amazing too. My shop is @ 26X26. I recommend ducting the system. I tried a portable single stage and flex hose before and hated it. Plan your ducting with the option to add on byplacing some wyes that are capped but can be used later. Pay the extra now go a little bigger than what you think and be done with it the first time.
