The INTERNAL and EXTERNAL CATEGORY of the fan can be different accord-
ing to the different risk AREA INSIDE or OUTSIDE the fan.
The basic rule between the INTERNAL and EXTERNAL category is as follows:
- For fans that are not fully ducted, consider the same CATEGORY of the fan.
- For fully ducted fans but in closed or poorly ventilated environments, consider
the same CATEGORY of the fan.
- For fully ducted fans, in environments that are not closed or closed but poorly
ventilated, one different CATEGORY between INTERNAL or EXTERNAL of the
fan can be considered.
