Grainger has contacted the product supplier and has been advised by them of the following.

The manufacturer does not offer a sound rating for this blower. The sound level will change depending on the application it is used on. This blower is designed to be mounted to equipment or ducted as well as several other applications. If you have more questions please call our HVAC tech team at 800-472-4643.
