This is the filter housing.Hello Heimlaga, nice set up ... do you still have the cyclone plans you can send me please ? I couldn't find it on Bill's website - a lot of the links are now 404... no, I 've just found it. Doh.
Can you show us your filter set up too, if you don't mind ?
Although it's not nice to hear that you have such troubles it does help to keep my own in perspective.
Thanks for the link to the calculator, very good of you... but man, now my head is spinning... gas pipelining is soo much easier than that ventilation. I will try it again when I've had more sleep.
The link above is one pete ( inspector ) sent me a while back....
My impeller is aluminium! Mind you, I'd have to be unlucky to get metal going up the chute, i dont run iffy timber through the machines, so it would only be if a bit of metal were imbedded in a tree as it grew.....
At the longest run from the motor+impeller I'd guess I would have had about 8m of ducting (up a wall, along the ceiling, and back down) and then 1m of 100mm hose. Even at that length it could "steal" a 1" (25mm) cube of wood and pull it along the ducting. Granted that system did not have a cyclone, which would reduce the flow quite a bit.Thanks.. Bill says minimum of 14" but it's on the right track.
I received similar shipping estimates a few years ago from Oneida when I asked about the Super Dust Deputy XL. The lowest cost just for shipping was about $1,000 for UPS because the item was too large to be mailed through the US Post Office. I bought the SDD XL from Toolovation in the UK and paid about £20 for shipping to Germany.I'm asking myself same questions as @Togalosh but with slightly less urgency as my new workshop won't be ready until next year. Just got quote from DeAnn at ClearVue for shipping to UK: $1400 economy, $2600 priority. Just to be clear these are shipping costs only and exclude the goods themselves and customs charges. Shipping cost is the same regardless of whether you opt for plastic or metal ClearVue system. But DeAnn points out shipping costs very variable in the age of covid.
Option C will certainly work, but everything sucked up by the extractor will pass through the impeller blades before going to the bags. For small dust particles, this shouldn't be a problem, but large chunks of wood could damage the impeller blades or get wedged between a blade and the housing. The cyclone does reduce the efficiency a little, but it separates most of the dust and all of the larger pieces sparing the impeller and filter.I have no metalwork skills but I have been thinking of (a) handing Bill Pentz plans to metalwork shop; (b) making Bill Pentz cyclone from plywood coated with glass and epoxy; (c) forget cyclone idea and install 2-3 bag bog standard extractor with 30 micron bags in outside shed.
(C) not seeming such a bad option as my understanding is that removing cyclone reduces power required to achieve CFM, I think 3hp instead of 5, which has other benefits
Thanks, will do. Not sure if article covers it but will need to know extra horsepower required to drive it ..,Josh - consider also a Thien Baffle (J. Phil Thien's Cyclone Separator Lid w/ the Thien Cyclone Separator Baffle). They're significantly easier to build, and may be a solution to the problems with option C that Mike's pointed out.
That's a more difficult one, as that information seems to be lacking for the Thien Baffle (vs cyclones). Certainly it will drop the airflow, and I don't think they separate as well as a cyclone. However, they're easier to build, and if the separation is good enough to not eject visible dust then if you're venting outside you might not need the filter bags (which will give you back some of the lost airflow).Thanks, will do. Not sure if article covers it but will need to know extra horsepower required to drive it ..,
They use them on the tabling of waste disposal units in commercial kitchens to stop cutlery going in.Ive been thinking about the above comments regarding metal and being sucked up off the floor etc. I guess when my system is powerful enough i will end up using it to clear sny floor mess.... so i thought about a branched downhill section of pipe and a box to collect heavier bits, but it would probably fill up quickly... a mesh guard inside would obviously block up with woodchip, but maybe a line of neodinium magnets around the mouth of the intake, or sweep it into a pile and use a big fishing magnet in the pile? ( ive got one )
