2 Stage Dust Collector Selection

Thanks! these look like the best, spec wise.  A little lower on the CFM listed, but that is probably because they are just being more honest, I can't see why a 5hp motor would pull less CFM than the 2-3's the other products have.
 
I'v been doing my research on cyclone dust collectors and found the same issue....specifically with JDS.  There 3HP is something like 2300 cfm while everyone else is something like 1700 cfm for the same HP.  Makes me not trust JDS!  I'm still learning but from what I understand 'Static Pressure' is really important.
 
I have Oneida. I will try to get back to you soon. They will size you're shop with tools and correct CFM's. Last pipe before collector should be straight with no y's . Gates should all be connected with system that turns collector on and off with opening and closing of gate in use. MARK
 
Do a youtube search on a Thein Separator.  You can make one and they work very well.  I use a 2 hp Jet with a wynn filter (very nice filters).  I made a Thein top hat separator and put a thien baffle in my jet spin chamber.  No complaints.  Used scraps (except the plastic) to make everything. 

I'm fortunate enough to have two shops.  I have a clearview at my larger shop. I like it even more but it's quite a bit bigger than my 3 car garage where I installed the Jet system.
 
A little late on the responce. I took the time to seal ALL joints with a GE gutter and flashing clear silicone. Even on the 5 foot straights I siliconed before snapping together. I used wide sweep 90's and in some cases adjusted them to 45's and used two to make the 90. This even gives a more gradual sweep. I get excellent dust pickup. Does it get it all? NO.   MARK
 
thanks jmarkflesher  . i was starting to think that my dc system that im building at the moment might have too many bends and be too long.
i did my 90 degree turns with 45degree fittingsand a short length of pipe in between.
hopefully there will be enough cfm left to run the tools
 
I started out using a remote control to turn the dc on and off. Mine runs on 220 volts. I burned out two contactors in 4 years. I now use a interrupter at the power source which has a continuous loop to all blast gates. Each gate has a window security magnet. When the gate is opened it trips the power to on at the source. MARK
 
about to pull the trigger on clearvue max (as opposed to the CV1800; to be more scalable for growth and an employee later down the road).

That's ~$2k.  (The lesser model is ~$300 cheaper).

I know I could build my own...with about $2k worth of parts and labor O_o and possibly miffing things up, I'm probably not going to do that.

This is without putting in ducting and blast gates and installation and wiring up.

Yes, I'm complaining, the most important tool in my shop is my dust collector (Festool vac included) and they are EXPENSIVE.

No wonder so many woodworkers suffer from dust exposure
...its shell out $2k+ ($2k just for the collector, then the ducting, then the collector by Festool so you can use the Festoys outside of the shop) or else?

+ I'll probably be getting an air cleaner...as no matter WHAT system you have, there is always dust created from other stuff you end up doing in the shop...

OUCH...

But I have a 15 month old boy; it's all worth my health and his right?

i neglected dc for too long.
no side affects thank god .
now i bit the bullet and ducted the whole shop out. new dc adn built a thien baffel seperater.
now there is a lot less dust in the shop. and my lungs i hope

i have jet air filter that does a great job .

I agree.  Just FWIW, I have a Dylos particle counter, and based on several months of gathering baselines in several buildings, outdoors and in my basement workshop, and based on several months of experimenting in the workshop, I think the ambient air cleaners are WAY under-rated for dust collection.  Yeah, you need to collect dust at the source, but my two Jet ambient air cleaners do an amazing job of filtering the 0.5 micron particles and everything larger.  Based on that, I don't worry as much about whether my at-the-source dust collector gets anything more than the stuff I'd otherwise have to sweep off the floor.

Yeah, I know, it's an unorthodox view of dust collection, definitely goes against the Gospel of Bill Pentz.  Go ahead, throw the rotten tomatoes  8)
