Hello,
I apologize for the confusion. In the bullet points it does say "Airflow output is on the switch side." I will see if I can update the text to make that more obvious. We only sell one version of the TW208P. You can not buy a version that has the airflow in the opposite direction. Please call us at 800-999-3267 M-F 8-4:30 to discuss the airflow direction on this fan.
Thanks,
Edit. I have added a new picture showing the airflow direction.
