Which one? "4.6" is a 45 and "4.8" is a 47 blower (many mfgs embellish thusly)

They advertise 300+ and 400+ cfm.

Prefer 4.8 but doesn't really matter. Just want to see real world numbers not what they decide to advertise.

The "400 CFM" they advertize is ~76% of max airflow.

That would require that they operate the blower @ 2736 RPM (0.76 * 3600RPM).

Anybody know or measure the actual RPM the blower is turning ?

Hydramaster does state a maximum of 14" lift on the 4.8 model.

I assume the 400 CFM is at the highest of the 3 speeds.
