Its gonna depend on the output of the unit. The higher the btu output the higher the cfm. So basically the bigger the firebox the more cfm it can move as a general rule. This I remember from researching the inserts before I bought.
 
My insert puts out 75000 if I remember right. There are inserts and stoves with larger fireboxs that put out even more. You would have to check the websites on a few stove manufaturers and see how much cfm per btu to get an idea. Its been 3 years or so and I honestly do not remember.
