I'm trying to understand what benefit there is to doing that inside a DC unit. Shouldn't you be seperating the dust before it enters the DC blower ? After it seems pointless.

I went through this same thinking process as yourself. Spending some time researching others comments on the net convinced me that you can keep a lot of dust out of your filter cartridge (or micron bags - whatever you use). I did not have such a large DC before, I bought mine used, modified it before using, and I can say after using it, that the filter pleats are very very clean. Would they be that way if the baffle had not been installed ? I cannot say - but I was convinced by others experience with both setups, and the number of people using this modification.  Besides, the baffle is a few hours work, using scrap in the shop - whats to loose by trying ??

I had the same question. http://www.jpthien.com/smf/index.php?topic=183.msg1046#msg1046

But I went ahead and installed one anyway. Seems to work great.

I think that I have a simple plan for an air cleaner - I know I built one !!

Send me a PM if interested

            What size of hose are you running to your machine ?

^{I'm afraid I lost you on the rest of your plans.  You're thinking of adding a neutral vane to the unit?}

OK, If you look directly into the intake, it seems that the air ramp obstructs the air flow - but perhaps it will not matter - hence my question.

The neutral vane is only a thought, I appreciate your comments, perhaps it is not a good idea, and I should just try the whole thing out before I start heavy experimentation.

This is an older DC that I just picked up. It is a two Hp unit, no data on the specs about CFM etc. In fact the impeller is only 10" in diameter, and replacement impellers from the manufacturer are 11 5/8" !?
It is in excellent condition, but I have a few questions....

You see that the front view into the collector opening, the air ramp seems to be in the way, or at least, obstructing the air flow. Is this "normal" looking ?

A thought that I had, is the addition of a neutral vane to direct the air flow downward, aligning the incoming air with the ramp. Then at the end of the ramp would be the Thien separator.

Any thoughts ??
