Ultimately, you'll need to match your extractor to the machine, and port size is a good indicator of what you'll need in terms of an extractor.
Typically, CT-type extractors will be suitable for tools with 50mm ports and smaller. So, a CT-36 will keep up with a 2-1/4hp router just fine.
That being said, a 6-8" jointer will likely have a 4"+ port, so you'll want a dust collector with a 4"+ inlet.
One option I haven't seen discussed here is the
Oneida Mini-Gorilla. When I was first getting my Shop set up, I was using a CT-style vac for my portable tools, and a Mini-Gorilla to serve my machines with larger CFM requirements. While it doesn't match the high static pressure of the SuperCell, it was sufficient to keep up with the following machines:
-- Dewalt DW735 thickness planer (4" port)
-- Hammer A3-41 16" jointer/planer (5" port)
-- KF700 sliding table saw/shaper (5" port)
-- LT14SUV 14" bandsaw (dual 4" ports)
-- 3hp router in a Incra router table with CleanSweep collection hood (4" port)
-- 16" wide belt sander (4" port). This particular machine was the outside extreme of what the Mini-Gorilla could keep up with, and required frequent filter cleanings (on account of the extremely fine dust), but it carried me until I could bump up to the RL160 I'm currently using. I'm a little surprised this machine only has a 4" port, it seems like it would be better served with a 5" or even a 6" port, as a 4" port really chokes down the available CFM....
The attraction of the Mini-Gorilla is that it doesn't take up much floor space, and is easy to wheel around the Shop. I was using a 10' length of 5" hose and it worked fine. I did try a 15' length of 5" hose and saw a noticeable decline in performance, so I'd recommend sticking with the 10' length of 5" hose, and just move the extractor from machine to machine as needed.
Anyways, the Mini-Gorilla served me well for several years. The only down sides are:
-- When I moved to larger machines like the 16" jointer/planer and the shaper, I would fill the 22 gallon tub quickly, sometimes several times in an hour depending on what I was processing. Not necessarily a problem for hobby use, but when "time is money" it was getting expensive to stop every 20 minutes to empty the tub.
-- This extractor really isn't suitable for any kind of meaningful central ducted system. As my pace of work increased, I needed a central ducted system, so I bumped to the RL-160, which has a 100 gallon capacity, higher static pressure, and a 6" port which is better suited to a central system.
