Is this Premium Damper standard in any of your bath fan models?
Is a non-premium damper standard in any of your bath fan models?
Thank you for your question on the model RDF1 premium radiation damper. The RDF1 is a radiation damper that can be added to numerous fans when a ceiling fire damper is required on the exhaust fan. Our ventilation fans do include a regular damper/duct connector. Please contact the Technical Service Department at 800-637-1453 for further assistance.
