Cyclone Talk, Again · 10-27-2009, 09:31 AM

For the past 5 years I've been running a Jet 1100 dust collector in my hobby shop, and in that time I've tossed around "when" I'm going to upgrade to a cyclone system with better fine dust collection. Well, I'm back at it again ...

Cyclone talk has become similar to a religious, or political, argument. I'm fully aware that people stand on different sides of the fence, BUT I still want to hear it all again.

What I do know is that (1) fine dust collection is a must, (2) I want a system that will last me many years, (3) I'm not looking for a new project in dust collection, but rather a quick assembly, (4) 3HP minimum, and (5) I'm EXTREMELY tight on space -- but somehow always seem to squeeze it in.

After my initial research, I'm pretty much down to these ... HOWEVER I'm open to suggestions.

All this chatter had my brain rattling with questions and sent me back to the web.
I recommend you invest some time reading owner postings at Clearvue and also a re-visit to the Pence web-site.
My mind is made up. I will buy a Clearvue.

The other "fun" I've got (besides not enough room) is there is a good chance we will move in the next two years ... maybe even the next 6 months, depending on how a few things shake out. That makes me want to get something and live with an inconvenience/noise/whatever until we move ... then set it up "right". oh... the decisions...

gritz... I'll get myself back over to that site and look around.

Here's a deal on 2 Clearvues (and a bunch of other stuff too):

A good deal always gets me off the fence.

Jeremy,

I've been to the Oneida plant in Syracuse...they run a first class operation, employ local folks and all their stuff is made in the USA. I lived there from '67 to '80. Great place if you like snow...lots of snow.

They used to be just north of Oneida lake...hence the name.

Everyone I know that owns an Oneida..loves it.

Don

Thanks again for all of the feedback and opinions ... they have all helped. I'm closing in on a decision ... I'll keep y'all posted (and hopefully I'll have an opinion at some point!)

I think everything has been covered, but would like to dispel one misconception regarding discharging DC air outside. Unless you leave your DC on the entire time you are in the shop, or at least for long periods, discharging outside won't have as big impact on temp as you might think, even with a 100% turnover of the air mass. What you say?!?!?!?

The reason, air stores little of the BTUs. It is actually the mass of your shop- walls, ceilings, machines, benches, and floors, especially concrete walls or floors, that store and maintain heat or lack of it. If you change out the air, the new air quickly warms or cools to the temp of your shop mass. A prime example- a fridge or freezer- when you open an upright unit the cold air is replaced by room temp air. Close the door, and re-open it a minute or two later. Nothing defrosts, or even warms up and the inside air is as cold as the first batch that spilled out.

The one item that can be impacted is the humidity of an air conditioned shop.

I take some exception to your thoughts on air exchange Alan, If you are operating a 1500 CFM DC with exterior exhaust that means that 1500 CFM of conditioned air is leaving the shop. Whatever your heating/cooling means you are using has to work that much harder to maintain ambient temperature. Although I am well aware that building/content mass gives a flywheel effect I would be more comfortable with keeping conditioned air in the shop. Back in ancient times when I worked on kitchen ventilation systems when we installed mega sized range hoods we had to install make up air units in the kitchens to avoid overtaxing the dining area HVAC units. JMTCW.

Two different situations- you must have decent takeup air to ensure proper venting of the kitchen gases/fumes. Certainly, the ideal is to maintain a closed system in your shop, to recycle the air, but it is not necessary to maintain a comfortable temperature, except as I noted (running the DC continuously, extremes of temp and especially humidity).

Without turning on your HVAC, your shop's thermal mass (specific heat) is going to warm or cool the shop air many times over before you see much of a change in the temperature. I refer to opening the door to the refrigerator as an example- unplug the frig and check the temp inside. Then cycle the door open 30 seconds to dump the air, close it for 1 min. and do that a dozen times, then measure the temp- you will see very little change because air has a limited thermal mass as compared to the contents and cabinet. It is a matter of BTU's and specific heat. You can compute it yourself.

I am picking up the Clearvue with motor on Saturday. Let me know if you are interested in the other one without the motor.

Nice score! This guy has a lot of stuff for sale ... I had my eye on that Ridgid MSUV ... just don't think it would be worth the drive from Charlotte.

Though I started this thread with a post on the units I was considering, I expanded my view after going through this and in the end decided to buy a Shop Fox 3HP cyclone unit from North Carolina Woodworker sponsor and friend Rick at The Woodworking Source. And further along the North Carolina Woodworker friends network, another members son is an electrician and I've got him coming over this weekend to start re-wiring the shop. Now I just gotta figure out how the duct system will happen ... and how I'll pay for that! I'll keep you guys and gals posted.

Good luck with the Shop Fox Jeremy, and I'm sure that you'll be happy with it.

So where are you going to mount it, inside or out ?

The Shop Fox comes with a stand, so for now it's going to be in the corner of the shop (the only place I have any space). Until we figure out what we are doing long-term with our house (staying or moving), I can't invest anything more into the shop in that way. However, when that is all figured out I will eventually plan to get it out of the shop in a dedicated room for loud machines. I was looking at the sound produced by this machine and it's only 3db more than my current unit ... so I'll live I figure (plus I wear a head set ear protection 90% of the time)

Great, glad you have a plan in place. Many of us "need" to improve our dust collection systems and are interested in your reviews. I know you'll keep us updated on the process and provide a performance evaluation.
