7. Which external fan suits my three-phase motor?

The external fans are precisely adapted to the IEC standard motors. The designation of the external fan cover therefore corresponds to the engine size. These are as follows: BG 63, BG71, BG 80, BG 90, BG100, BG112, BG132, BG160, BG180, BG200, BG225, BG250, BG280 and BG315. If the fans are used for other engine brands, new mounting holes often have to be drilled.

External fan (multivoltage) can be operated single-phase and three-phase. Available from size 63 to 132.

The external fan can only be operated in three phases. Available from size 160 to 315.
