Dunno, in terms of just the Dyson fan, the bit implementing the main feature of the offering needs just high pressure air so it could be just as well connected to a high pressure air feed. The fact it comes integrated with a turbine that has a blade means there IS a blade included with the product, but it's kind of an implementation detail that could be implemented some other way. The engineer in me wants to read this "omg they have invented an efficient bladeless turbine" but that's not really what this is about.
