I was looking at the 20" and 24' fans (AMX-FAGEC20 vs AMX-FAGEC24) and the descriptions and specs make no sense. According to the descriptions/specs the 20" fan moves more air, uses less power, runs faster, and is quieter than the 24' fan. They both have the same overall dimensions although they are less than the 24' fan diameter. Can someone please straighten me out?

Answer This Question

The sizes and airflow of these two models are different.
