Its hard to imagine this hasnt been covered already, so just ignore if so.
But shouldnt the blower go BEFORE the cyclone, and not after?
Blowers can push more than pull, so any pressure drop through the cyclone would be handled better by putting the blower in between the equipment and the cyclone (and as close to the machine as possible - to where it 'T''s off to other machines) - to put as much of the pressure drop on the outlet side of the blower.
(yes, there is convenience of mounting the blower right to the cyclone)
I wonder how much effect this would have? Maybe the cyclone itself is negligible pressure drop?
