@@TheFanUniverse u were right kdk quality is really going down i have a kdk wall fan that started to make weird sound so than i put oil in it but 2 weaks later it happened again :/. BUT old kdk are the best i found a kdk at my school it was VERY BAD ABUSED the motor sometime stop due to bearing locked up but ITS STILL ALIVE!
is the back hinge have a chance to stuck someday? is it better to choose this version with automatic hinge or other version with pull mechanical hinge?
Thanks! The grille is used to catch grease//oil boiling off pans so that it hopefully won’t make the fan itself & the wall on the output side of the fan dirty
