How loud is this fan? Is there a sone rating?

Thanks for reaching out! This model doesn’t have a published decibel rating, but it is AMCA air and sound certified and designed for low ambient noise for quieter operation. Sound levels can still vary depending on how and where the unit is installed. If you’re planning for a sound-sensitive space or want a quieter setup, feel free to give us a call and let us know what you’re trying to achieve—we’d be happy to help narrow down the best options to match your noise expectations.
