Not sure how slow we’re talking. If just somewhat slower than what you’ll expect it probably is a bit gunked up. Hair and all sorts of stuff gets pulled into and wrapped around the rotor/shaft. Does the blade spin freely when off? Short of taking it apart and cleaning, I’d start with oiling the front and rear ports. Use a light sewing machine oil. Such as zoom spout. You can see the hole atop the rear part of the shaft. May be just dry. My made rite spins very fast so for it to be slow is notable. May want to open it up if oiling doesn’t rectify it. As far as pushing air, the pitch on the blades may be pretty flat.
