The average life span of a fan tray assembly varies depending
on the actual environment. Environments can be classified as
follows:
Class A environment: refers to the indoor environment
where the ambient temperature and humidity are
controlled (including inhabited rooms).
Class B environment: refers to the indoor environment
where the ambient temperature and humidity are not
controlled or the common outdoor environment where
only simple shelter (such as awning) is available and the
humidity occasionally reaches 100%.
The average life spans of fan tray assemblies in different
environments are as follows:
Class A environment: 6.5 years
Class B environment: 5 years
NOTE
The previous life spans are the average values concluded based on the
test data in a lab and the theoretical model, rather than the actual
values. They are for reference only. The actual life span must be
determined based on the environment conditions of a specific area. In
