| Hi Grader Guy, well worded response and some of it is accurate. It is true that the Cleanfix fan blades are cupped in the correct direction both in standard and reverse pitch. I can tell you that to the best of my knowledge Flexxaire has never had a problem with insufficient reverse flow and prefer to optimize performance in the default airflow direction. Also, it should be known that the Cleanfix fan has to use skinny or narrow blades, and those come with considerable drawbacks.
Thanks,
Rob | |
