I've been watching for a Kundig for you but few on the market.? DC for a WB takes up a lot of room.? I run a used Coral I found for $800 and added four AFF bags, 8' tall.? 7.5 hp? motor and works will with the 43" dual drum and my big old machines in storage
building, other than hauling heavy hoses around.? My ceiling height in garage shop is 11' so my blower and motor sit in the attic.? Cincinnati RBE 9 with four Wynn filters. ? I agree with Jason, the filters are not the easiest to clean but I don't run the
25" WB much.
The gray AEM were also a nice sander but they usually need more power than I have.? The SCM two head shares a 30 hp motor.? Good on amps but not ideal.? I run 120-180 and if I need something more coarse I take out the platen on the second head and leave the
settings of the two drums alone.? It is finicky work aligning both heads on a manual unit.? Dave

I currently have a franken system Oneida, upgraded a couple times over the years.? Same parts as the 5HP Smart CNC (high pressure) with dual big HEPA filters.? Runs great but if I get a big wide belt I may need more collector.? If I do I would end up with a new cyclone and fan and my own VFD setup.? So many used 43¡± wide belt sanders but few 37¡±.? I could run a 37¡± easily, maybe a two head 37¡± but not sure about a 43¡±.? Sadly I don¡¯t have enough ceiling height were my current cyclone sits to go bigger and move the collector and a bunch of duct is unappealing. ?

Joe, we are one the same page.? My comment wasn't for the pro designers but for the guy doing it himself.? I've had people send me calcs comparing 6,7,8" at the same fpm rather than the same cfm. ? I do think CV was
a factor in helping Oneida step up their game and add some design changes to the cyclone and offer more choices for the larger machine hobby types.? I still think CV should step up into that market a little more.? Bill started his design as a low cost alternative
using PVC 6" and a lower cost cyclone and motor combo.? He realized that 3 hp was too little but didn't think a full 5 hp was necessary for the type of system he was developing, it just was the next size motor available.? That need? came with the Max. ? It
was a a real benefit for those running 4" mains and flex but?? I'm assuming the Felder and MM guys are running larger equipment than most home shop guys so they can benefit from additional capacity.?

Total length of duct and diameter, angles, flex, transitions, etc.? The right design balances factors.? ?I am not a fan of the clearview but I understand his cyclone is more efficient than Oneida's.? the bigger duct for home shops became internet gospel when people were running 4" everywhere.? 4" resistance per ft is way higher than 6".
