Note that Zoom did not seem like he was actively fighting against Barry. Furthermore, after Zoom was 'depowered', Barry stated that if he began moving again his connection to the NSF would be 'resparked'.
ie. the only way to keep this version of Zoom at normal speed levels is to first depower him with the aforementioned tech, then keep him perpetually immobilized.
Professor Zoom blitzes Superman, Hal, Booster Gold and Rip Hunter -- whips up a cyclone to own Rip/Booster a little more (adding insult to injury) -- then, once he was done playing, Zoom leaves the battlefield by simply 'jumping' back into the timestream:
Zoom is learning how to manipulate the speed force in ways that make the Flashes look like idiots...
"The speed force is tied to so many things when you pull back the electrical curtain and see it for what it truly is: time. All of time. Existence moving through reality. Kinetic energy. Temporal energy. A storm of intelligence and experience that can connect me to everything and everyone":
