This is the fan blade and motor, as a complete assembly.
2 fans are required, and are sold individually.
This unit is made by JP Group and is manufactured in Denmark. It is not one of the cheap Chinese knock-offs found on eBay and other sites for a lesser price. Those substandard Asian units are generally, unbalanced and poorly constructed and often vibrate severely when running. As with anything in life, you get what you pay for.
MOST OF THESE FANS HAVE BALANCING WEIGHTS (CLIPS) ON THE FAN BLADES. DO NOT REMOVE THEM OR MOVE THEM FROM ONE BLADE TO ANOTHER OR YOU WILL HAVE A VIBRATION ISSUE.
The plastic fan blade is not available as a separate item.
