Functional description

The fan-and-filter unit in conjunction with the corre-
sponding outlet filter(s) is used to dissipate heat loss
from enclosures, ventilate the enclosure and protect
temperature-sensitive components. This is achieved
via the direct infeed of ambient air, the temperature
of which must be less than the admissible enclosure
interior temperature. The system is fitted into prepared
cut-outs.
