Steps to choose Panasonic Ventilating Fans.

---

1. Calculate the capacity of the room

                         Capacity of room = Width x Length x Height (Unit : metre)

2. Calculate the required air volume

                         Required air volume (CMH)  = Capacity of room x Air change rate

      3.    Compare the required air volume with the specification of fans

Example :

            Living room, Width = 3 m., Length = 3 m., Height = 2.5 m., Air change rate = 6 CMH with requirement for Ceiling Mount Type

               Capacity of room  = 3 x 3 x 2.5

                                                   = 22.5

               Required air volume (CMH) = 22.5 x 6

                                                                           = 135 CMH

               The suitable Ceiling Mount Ventilating fan is FV-24CUT3 (140 CMH)
