What is the expected lifespan of a depressurization fan?

The expected lifespan of a depressurization fan is generally around 11 years, which is a reasonable estimate based on both industry standards and the maintenance practices typically associated with these systems. Depressurization fans are designed to operate continuously to reduce radon levels in residential or commercial buildings, meaning they need to be durable and reliable over time.

Factors contributing to this lifespan include the quality of the fan's construction, the specifics of the environment it's operating in (such as humidity and temperature fluctuations), and regular maintenance, which can help extend the operational life. Regular checks and timely replacements of parts can also influence how long the fan will effectively work to mitigate radon levels. Ultimately, while some fans may last longer or shorter depending on different circumstances, 11 years is a commonly accepted benchmark in the field.
