Nice pictures, knotscott.
Manitario, Bill Pentz has is latest info on his website: http://billpentz.com/woodworking/Cyclone/
The ClearVue appears to be Pentz's design implemented. Phii Thein complains they stole some of his design
. The ClearVue is a bunch of parts connected with MDF. The parts are the plastic cyclone, a 5hp motor, a 15" or 16" impeller, and two tall filters.
They sell the parts separately-motor $375, impeller $225, cyclone $450, filters $300/$400 (either $150 or $200 each)-but the sum is high enough that it pays just to get the completed unit at $1595 or $1695 depending on the filter chosen. There is probably a hefty shipping charge on top of that, but the individual components should be light enough not to require a fork lift for unloading. Additional pieces may run a few hundred more…say $2000 total.
The Clear-Vue probably defines the upper limit of the units we have discussed here.
This is a YouTube of the ClearVue assembly, giving lots of good shots of the details:
Can an HF based unit come close? With a 20% coupon (in every issue of Circle Track magazine) the dust collector is $160. The filter from Wynn
is $150-$170 plus shipping; they shy it fits the HF without issues. You can get a cyclone to fit it for $200-$250 on eBay. Miscellaneous extra parts would probably add another $100 or so for a total of about $675.
The Grizzly 1.5 hp cyclone is about $150 more, but probably doesn't include as good a filter. The Grizzly 2hp canister with the cyclone added the same way has the HF would be about the same, but again the filter probably wouldn't be as good. The cyclones look similar but the aftermarket one looks a bit better (taller cone).
Loren, his tests are interesting but his macro probably wasn't enough to see anything in the range we are talking about. I have a bellows with reversed 20mm lens to get 10x (enough to see the pixels on a TV screen). There are bellows extensions to double that. He had a simple macro lens. 1 micro is VERY small, about 100-200x smaller than those pixels.
He did talk about the air being cleaner with air blowing through a filter. A stop at Home Depot will show the filters come in a variety of strengths. The air filtration boxes that are sold are nothing more than blowing air over a filter. and could probably be constructed inexpensively using furnace filters and a modest fan.
The runtime issue for filtration is an issue. Furnaces run intermittently based on temperature. Commercial systems run to limit CO2 buildup from occupants. That isn't a residential problem because the occupancy density is much lower and the people are often at rest. However, running the house air through the filter is important if air quality is the concern. I'm not sure if any thermostats handle it. a third party does make a cycling device
. It may be useful to have if a lot of woodworking is taking place in the house. Or the furnace fan can be left in the on position during woodworking and for a few hours afterwards.
