    Maintenance & Safety Measures

    As an electric device, a duct fan surely has some safety measures. So here, I have added this maintenance and safety guide for you.

    Maintenance Guide

    For maintenance, you have to give the extractor fan some rest. That means you should not keep the fan running for a long time. That can make the motor get hotter, and then it may burn inside.

    Safety Guide

    As this is a duct fan, its general purpose is to make the airflow through the growing place. But if the place where you put the fan is suffocated and there is no ventilation, then the fan cannot flow air. This can lead to internal problems for the fan.

    And in a suffocated area, if the motor gets hotter than average, this can also lead to accidents.

    So the two things you should do to ensure safety is not to make the fan get hotter and keep it is a place where it can pass the air thoroughly.
