Anti-radon in-line duct fans are designed to mitigate radon gas in indoor spaces. Radon is a naturally occurring, radioactive gas that can seep into homes and other buildings through the ground. Anti-radon in-line duct fans work by drawing air from the basement or crawl space of a building, where radon gas is typically most concentrated, and exhausting it to the outside through a vent

Portable in-line duct fans are designed for temporary or mobile applications. These fans are typically used for spot ventilation in construction sites, workshops, and other temporary workspaces where a permanent ductwork installation is not practical.Portable in-line duct fans are lightweight and compact, and they can be easily moved from one location to another. They are typically designed to be plugged into a standard electrical outlet, and they may come with a flexible duct that can be attached to the fan for directing airflow.
