Thanks for the formula in your other post. It’s different than other formulas I’ve used.

The Canfan RS I referred to is a centrifugal, if not someone should call out its manufacturers for false advertising.

Seems I misunderstood the definition, the air comes in and out on and axial plane but the impeller is throwing the air out like a centrifugal but its been redirected by the housing . Never really noticed that.

Yeah I have a few, though they used to be called ruck fans before rebranding for the legal market I think.
The drone bothered me after a while because im sensitive to that frequency but they are the perfect work horse and the quality of engineering is top. Last forever.

Isn’t that the worst of what we do? Once you hear it you can’t unhear it. It drives me nuts! Same as when as res does a feed or dehu turns on.
