This was my response to Cobb's contentions:
After reading the over-view analysis of the featured vacuum motor, in my experience in manufacturing, I feel compelled to point out a few key aspects which would be tied to and seriously considered whenever selecting a particular motor and its' "performance".
1. Any extractor is more than the sum of its' components, period. (I believe long ago, this was a patented phrase of the honorable Lee Stockwell)
2. Another big "variable": The above spec's, etc...does not incorporate another key aspect called: "design", ( most commonly over-looked in this industry). This is why one race car may over take another because of its unique incorporated design, rather than the power of the motor-----and performance ---(side note: 2 different aspects here, btw).
3. Example: A 200 hp engine on a tractor is much different than a 200 hp engine in an automobile. Again, both were designed for a much different purpose and performance, and so is the design of that engine too.
4. When "comparing" air watts over another vacuum motor, we must be careful and consider: Sealed bearings; position of the bearing to alleviate the effects or contact of water ingress; internal fan blade design; rpm's; amp. draw; life of motor (brushes,etc) which all relates to a much greater value to the operator.
Hopefully this information will help some when deciding what would be their best buy and value.
