I've got a Trinco Model 36/BP2 Cabinet and a 45ORC Abrasive Separator.
This pair has never worked right, and I find it aggravating.
The separator hose attaches to the bottom of the cabinet and is supposed to remove the abrasive from the cabinet and separate the dust and debris from the abrasive. Abrasive should end up in the bottom of the separator and dust and debris in the filter bag.
What actually happens is, most of the abrasive just collects in the bottom of the cabinet, and has to be emptied out of the bottom door shown in Pic 3.
I also suspect the design of the separator is poor, as a lot of abrasive ends up in the filter bag along with dust and debris, so the cyclone action is poor.
After looking at and studying cyclone designs, it's very obvious this Trinco cyclone is not even shaped similar, which I think is an obvious reason it does not work well. Frankly, my impression is that the cyclone separator was not "designed" at all, but simply thrown together to resemble a cyclone with little engineering employed. This is obvious by the way it DOES NOT work. Another curious feature is the damper located in the inlet to the separator. I can't see any reason to have a need to cut down the flow into the separator, as it already doesn't remove most of the media from the cabinet. Another point that makes me suspect no real engineering went into this design.
The shape of the separator shown on this page is not anything like other cyclones that are proven to perform well.

I've owned this unit for years, and don't use it a whole lot, but it is frustrating when I do use it that the abrasive needs to be emptied out of the cabinet, then also what collects in the bag needs to be screened.
Extra work that should not be necessary.
My questions at this point are, what can I do to improve operation?
I am willing to modify the separator as needed to make it work as it should. For starters, I wonder if a smaller diameter hose between the separator and the cabinet would increase the velocity and help to empty the cabinet more efficiently?
I'm eager to hear any and all suggestions to get this thing working like it should. As a last resort, I'd even consider fitting a completely new cyclone of proven design if this one can't be made to work more efficiently.
Thanks for any help!
