PROBLEM TO BE SOLVED: To allow a ventilator to be corresponded to both the integral form with a panel and the incorporated form of a ceiling material by providing the casing of a ventilator main body with a surface panel having a grille part that covers the suction opening and discharge hole, respectively on the surface, and mounting an auxiliary panel removably so as to close the opening part of this surface panel. SOLUTION: In a ventilator, a surface panel part is constructed so as to be separated into an outside panel 5 and an inside panel 6 which can be removable for maintenance. The inside panel 6 has the grille part which covers a suction opening and a discharge hole, respectively, and it has an opening part 6a between both grille parts. A decorative auxiliary panel 7 is removably mounted so as to close this opening part 6a. When this surface panel is used under an integral specification, namely it is used under a standard condition (in the form of shipment), the auxiliary panel 7 is mounted to close the opening part 6a. On the other hand, when the surface panel is used under a specification of incorporating a ceiling material, the ceiling member of a setting place is incorporated into the opening part 6a for its usage. |
