COOLING

Filter fans are used to provide an optimum climate in enclosures and cabinets with electrical/electronic components.

The interior temperature of an enclosure can be reduced by channelling cooler filtered outside air into the enclosure

thus expelling heated internal air. The resulting airflow prevents formation of localised hot pockets in installations

and protects electronic components from overheating.

The Filter Fan Plus series uses a new air-flap outlet technology for the air outlet and thus reaches a high degree

of airflow. A ratchet mechanism is used for mounting and provides high stability and tightness. Depending on the

application there are two systems that are available – the FPI or FPO system. The FPI system is a standard installation

with a filter fan in the lower part of the enclosure which ensures that fresh air is fed into the enclosure (airflow

direction "In"). This system consists of a filter fan and exit filter. Whereas in the FPO system, the filter fan is located

in the upper area of the enclosure to avoid heat buildups (airflow direction "Out"). The FPO system is composed of

an intake filter and exit filter fan. The Filter Fan Plus series may also be used outdoors with appropriate protective

measures or when equipped with weather proof accessories, e.g. Hose-proof Hood FFH 086.
