10.2.- COOLING FANS
The cooling fans must operate correctly to avoid overheating in the active filter
components.
The device has high-speed cooling fans, with an estimated useful life of 40000 hours.
Nevertheless, this useful life can be shortened depending on the conditions of use (tempera-
ture, humidity, environmental pollution). In the event that the fans lose their efficiency, the de -
vice's performance will deteriorate.
The following symptoms in the filter behaviour could indicate a deterioration of the fans:

Increase in fan noise.

Increase in temperature of the device under the same environmental conditions and
load.

The
AFQm
regularly indicates a temperature alarm.

Reduction in the filtering capacity.
The set of fans must be replaced if they have exceeded their useful life or show signs of dete-
rioration. In such cases, Circutor will provide a spare part that consists of a set of fans so that
the device can be repaired quickly and easily.
For an installation with devices in parallel, all of the fans must be changed at the
same time.
