风扇盘，CFR

Feature: Roof fan plate for mild steel semi-compact and combinable floor standing enclosures.

Advantage: Up to six ventilation fans can be mounted within the roof plate providing forced ventilation into the enclosure. The roof plate is mounted in combination with the ventilation roof plate, CVR, providing a degree of protection of IP31.

Benefit: The enclosure can be cooled in incremental steps depending on the number of ventilation fans installed. The forced ventilation provides a high cooling capacity which is a good solution in environments when the ambient temperature is 10o or more, under the enclosure's desired internal temperature.

Comment: The roof fan plate must be mounted in combination with the ventilation roof, CVR. It is recommended to also install exhaust filters in the bottom of the enclosure to let air circulate properly. The cut-outs must be covered by either ventilation fans, DFN, or cover plates, DFC, depending on the amount of cooling required.
