Topic tags/keywords: clearvue cyclone dust collector thien baffle

My Grizzly G0562Z 3 HP dual canister dust collector with fine, pleated filters works very well. I am considering adding a cyclone separator body to ramp up its performance. I’ve looked at three: Super Dust Deputy XL, ClearView CV1800, and from Bayshore Wholesale of Caroga, NY.

I have read reviews from happy customers for the SDD/SDD XL and the cyclone from the guy in Caroga. I have not found anyone who has added a CV1800 to an two stage DC. I have been in contact with ClearVue and they believe the CV1800 will work well with 1 HP to 5 HP two stage DC.

I’m wondering does anyone knows of a review, etc., where the CV1800 was added to an existing single stage DC?

Thanks.

WoodNDust,

I cannot speak directly to your question. I have a CV1800 Bundled system (that is, all components were bought together). Since the CV1800 is a 5 hp unit, a 3hp retrofit may not perform as my experience suggests. There are other factors that affect performance beyond the power of the fan. I assume that by performance, you specifically wish to separate out course dust from fine dust and prolong the time it takes for the filters to load with dust. By my thinking, reduced filter loading can positively impact the volume of air pulled from the machines.

I have used the CV1800 since late 2015. In that time I have cleaned the filter stack twice, even though prior to cleaning I noticed no decrease in suction and only a small decrease in outlet air velocity measured with a pilot tube/manometer installed in the outlet air stream between the impeller and filter stack. Also there was very fine little dust in the fine dust collection containing on which the filter stack sets.

The second filter cleaning was performed by blowing compressed air through the filters. My recollection is that I dislodged about 4 gallons of fine dust. During the time I collected that 4 gallons of un-separated dust I did not count the number of times I emptied the 40 gallon dust bin (guessing, maybe 10 or 15 times). Most of the work I did to generate that wood dust was from planning, sawing, shaping and sanding (the CV1800 is connected to a downdraft sanding table where I do almost all sanding). I am a hobbyist so I generate a small fraction of the dust compared to a commercial shop.

Personal experience aside, there are several factors that affect cyclone efficiency (% of small particles separated from large particles). I found this paper entitled “How to Select and Maintain a Cyclone for Maximum Performance” which discusses those factors, including cyclone design. Perhaps this paper can be of some help as you consider your options.

Thanks for sharing your experience and this link. I downloaded it and will read it over the weekend.

Keep me posted on how you go, Wood. I am in same boat as you are (dual canister 3HP Grizzly). I am seriously considering the SDD XL to replace my Thein baffle. Were you thinking of placing the motor on top of the cyclone body?

Mounting the blower on top of the cyclone is not an option for me now. The ceiling height of my shop is a little under 8’ and a full 8’ is required to make it work.

I have read several reviews of similar single stage DC being upgraded with Super Dust Deputy XL’s with good results and with the galvanized sheet metal cyclones produced in Caroga, NY. Both of these units are in the $200-$240 range, whereas the CV1800 cyclone body is $450. The issue is not so much the money as it is the performance; that is, will my set-up get much better performance with the CV1800? If so, then spending the extra dollars makes sense.

I will definitely keep you posted, Holbs.
