2.6 Filter configurations and designation with embedded ventilation
If external air flow for cooling is not available, then the filters contain embedded ventilation, which means the
filters
contain fan
and
aux. power supply
.
The open frame filter configurations are shown in Table 12 and Table 13, if external air flow is not available
and embedded ventilation is equipped.
Table 12 FN 3440, FN 3450, FN 3452 filter configurations with embedded ventilation
Table 13 FN 3441, FN 3451, FN 3453 filter configurations with embedded ventilation
Remark:
Frame sizes A, B, C do not require air-flow for cooling hence they are not equipped with FAN and
AUX.
