The Austrian's suck at trying to sell their dust collectorswhen they try to translate to English and going imperial at the same time. Anyways if you have the money take a look the Oneida DC's that have a Rotolock incorporated in the design. I believe they start at 5 HP. No more worries about plugging filters and having a sealed container to collect the dust. You just have to have good ceiling height.?

John, here's a screen grab from the Felder website, and matches what is in the printed catalog: Nominal air flow 853 cfm. The 1,450 is cubic meters per hour. Just wanting to get the units straight. Now, the 853 cfm is listed at ~8.8" water lift, whereas most duct collectors are marketed at closer to 2" SP, so that's where they are getting into the 1000+ cfm range, and makes the RL 160 look like it has relatively lower performance, whereas at 2" sp it looks like it's more in the 1000+ cfm range.?
I'm revisiting the Oneida collectors. I see the Dust Gorilla Pro has a HEPA filter, whereas the "high pressure" unit has 99% collection efficiency at 0.2-2 microns, so definitely not HEPA..... I'm going to see if NordFab will collaborate with me to get an appropriate sized collector to match an efficient ducting layout.?
