This C-90A C-90B side panel can be used for the left or right side. Overall measures 16 x 22 inch.
The C90 panels have loose plastic granules inside. Friedrich tells us the granules are from the manufacturing process. Customers have reported the fan vibration causes the granules to rattle. Our panels are genuine Friedrich and they all have a few loose granules.
This C-90A C-90B panel is a different color than the early C-90 (manufactured prior to 1995).
