Want to Buy a 16” impeller for use with Clearvue cyclone

Want to buy a 16” impeller for a Clearvue cyclone. Needs to rotate counterclockwise when viewed from the fin side. Prefer steel, backward inclined fins. Would consider a blower assembly as well.
Clearvue sold me a cyclone and will sell me a motor, but for some reason won’t sell an impeller or blower housing. I’m currently running a 3hp motor and 14” impeller and am only drawing 11.3A/220v.
Thanks,

When I upgraded a few years back it was impossible to find just a blower assembly. I thought I was going to have to buy a complete DC and throw away all but the motor & blower. I wound up on the phone with Rikon's parts department. They had a unit damaged in shipping that they parted out fo me.
Once I had the motor & blower they sold me the largest impeller that would run in the housing as a repair part. Nice people to deal with.
I woult not buy a motor seperate from the blower for fear of mounting issues. Buy them as a unit.
Thanks for the tip, unfortunately Rikon doesn’t sell anything nearly large enough for my application. I’m trying to get to a 5hp motor and 16” impeller. The biggest they list is a 2.5hp cyclone with a 14.5” impeller that spins the opposite direction as my cyclone.
Yeah, my reply was more about the "parts department mindset" for finding components. Good luck!
I just re-read your last... why does the direction of the impeller spin matter? As I understand it, the suction is through the central, vertical pipe... essentially non-directional. Does the Clearview set up differently than other cyclones?
An impeller with backward inclined fins spins with the convex part of the fins forward. A straight blade impeller doesn’t care which direction it rotates. Clearvue uses backwards inclined impellers that rotate counter clockwise when viewed from the fin side. The output of the blower needs to be on the opposite side of the cyclone intake. You want the the impeller to rotate the same direction as the vortex inside the cyclone. Matching the rotation direction is an efficiency thing. My Clearvue cyclone has a clockwise rotation when viewed from the top—that is the intake is on the left side. This is my layman’s understanding. It makes cobbling together components that much harder…
Thanks for the explanation, I can visualize the internal rotation. It has me wondering which way mine spins... I had never given it a thought.
To take it a step further: Could there be an advantage to the airflow "stalling" to change direction at the bottom of the pipe in terms of more particles settling out to drop into the barrel? Airflow might suffer, but the filters will receive less material, so in the end it could even out. We need one of Ben's geeky pal's videos here!
That’s a good question. I read about the concept of having the impeller spin the same direction as the vortex on Bill Pentz’s site. If I remember correctly, it matters less on lower powered cyclones than it does on higher powered ones. You probably induce a lower pressure drop spinning the same direction, but as to how much I have no idea. I do know after reading that, I noticed that not one commercially available complete cyclone collector has an impeller counter-rotating the vortex. As far as people running Oneida Super dust deputies with whatever blower they have—there must be thousands rotating the opposite direction that pull dust just fine.
Speaking of cyclone pressure drop—I was shocked how much power a cyclone robs from a blower. My jet 3hp 1900 pulls 15.5 amps @240 with nothing but a 6” inlet on the blower. Add just the Clearvue (that has a 6.25” inlet) and that number drops to 11.3 amps @ 240. That’s almost 1KW of power difference. There is a reason they run those giant 16” impellers.
