The speed increaser is different from the more commonly seen speed reducer. Speed reducers typically have a lower rotational speed, whereas speed increasers already have a high rotational speed at the input end, and an even higher speed at the output end.

This speed increaser is used in conjunction with a blower. Those interested are welcome to download and study it.
