More about Squirrel Cage blowers:

Squirrel cage and regenerative blowers are low efficiency blowers, meaning that the output of these blowers is only about 30% of the power used to operate them. These blowers run at low pressure and low flow rates and are inefficient in removing water during blow off and drying processes. On the other hand, high efficiency Centrifugal Blowers produce more air power resulting high flow rates and pressure, which more effectively remove water from your product.
