Fan filters 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 Fan filter 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. The 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.
