I have been using a 5 hp Oneida Cyclone for the pass year and a half. I average about 50 gallons of debris a week, mainly from milling, not sanding. Dust and debris is pulled up and swirls around the clear flexible tube from the 55 gallon drum when there is only about 12" of material in the bottom of the drum. This happens as soon as the cyclone is turned on. Also, the debris below the clear tube, in the barrel itself, constantly swirls. The air flow diminishes fairly rapidly (about 4 weeks) after the filter is taken down and thoroughly cleaned. I have called Oneida multiple times and the response I get is "this is new, we have never heard of this before". I have tested the outside of the cyclone, barrel, and flexible tubes for leaks, and have none. I have talked to other Oneida 5 hp Cyclone owners and heard similar issues. I recently talked with a shop owner who has a Torit/Donaldson Cyclone and he told me that this is not normal. Is this normal or just a design issue with this cyclone? Is there a way to stop the dust from being pulled up from the bin and prematurely plug the filter?
