Square/ Round Diffusers
This round neck diffuser’s removable core makes installation and maintenance easier and has no visible mounting screws since it uses a snap-in mechanism. It ensures a tight ceiling pattern with a horizontal lip on the louvers which allows excellent mixing.
- Round inlet provided as a steel, factory-mounted square to round transition (SRM)
- Snap-in center cores can be detached and interchanged between the same size margins
- Available in standard White (WH) electrocoat finish that protects the diffuser from rust and other chemical reactions
