Cooling Fans are an integral part of transmitting equipment.

Their failure can cause equipment stress and damage depending on the length of time the failure is allowed to continue.

Premature fan failure is largely attributed to failure of the the bearing or grease within the bearing due to increased operating temperature, along with the dust and salt content of the environment within the hut.

The ideal environment for operating a transmitter fan is an enclosed hut with cooling.

Internal transmitter temperature monitoring will allow you to be notified of a fan failure.
