The Tjernlund RF Series Radon Mitigation Booster Fans are designed to improve airflow through compatible passive radon mitigation systems using 4-inch Schedule 40 PVC. Available in RF100 (100 CFM) and RF145 (145 CFM) models, the RF Series provides two airflow options to match different system requirements.

Both models feature molded 4-inch ABS inlet and outlet transitions for a streamlined inline connection, along with gasketed fan-to-housing connections for a compact, durable assembly. An attached 6-foot power cord and standard 120V plug-in operation simplify electrical installation by eliminating the need to hardwire the fan.

The RF100 delivers 100 CFM for applications requiring moderate airflow enhancement, while the RF145 provides 145 CFM for systems requiring greater exhaust capacity. Both fans are lightweight, designed specifically for radon exhaust applications, and include clearly marked airflow direction for proper installation.

Made in the USA by Tjernlund Products in White Bear Lake, Minnesota, the RF Series features a new patent-pending housing and transition design.
