I recently purchased a stack of QF12 (Balanced) and I wanted to know if the 'CO' icon in the middle is a sticker ... or is it etched (or similar) into the plastic? Also ... what does the icon represent? Sometimes I think CO, others CY, sometimes G.
Thanks for contacting and the video. Actually, it's a sticker in the middle of our fan, and our logo is a symbol of "CR".
