Additional Notes

The ACL640/ACL645 is AMCA certified, meeting industry standards for air performance and water penetration resistance.

The six inch depth of the ACL640/ACL645 provides greater acoustic attenuation than shallower models, making it well suited for applications with moderate noise reduction requirements. The standard straight blade offers dependable airflow performance, and the available channel and flange frame configurations give specifiers flexibility for both new construction and retrofit installations.
