I have an onieda cyclone topped with a 2hp Murphy Rodgers blower. I bought it used with a tall filter bag. There are no marking on the bag. I think the blower may be an mrt-5.
How do I know if the filter is big enough for the cfm? As soon as the blower starts it pops open and is fully inflated. Should I try washing it and see if there is any difference. I did install a neutral pipe in the inlet to the cyclone which increased vacuum buy 25-30%. I get very little fine dust inside the bag.

I think it may be this bag from wynn which has no micron rating.
