I suspect the Nederman is not a really good choice for a hobby level shop. It doesn't have a lot of static pressure capability. This limits it's performance for smaller port equipment. It also makes cyclone choice more difficult.
I like to compare fan curves and see how they match up with various system curves, so this is how I compare the three options that have been discussed here:
You can see that for 8" class ports the Nederman does really well. For 6" they're all about the same. For the small ports the VFD on the SDG is able to spin up a lot more pressure and so does the best.
Most hobbyist equipment will have 6" or smaller ports so the CV or SDG would be the better choice in my opinion.
Oops, sorry about the lack of labels on the graph. That's inches water column on the vertical axis and CFM on horizontal.
