APPSF Adjustable Pattern, Factory Mounted Blades
Plenum Slots
The APPSF features a curved blade pattern controller with an aerodynamic design, making it ideal for handling large air volumes with low pressure drop. The diffusers have versatile blades which can be set for horizontal left or right or can also be removed for vertical airflow.
- Comes with removable and reversible curved blade pattern controller
- The blades are factory-mounted
- Blades come with an option that can be reversed in the field to change the air pattern
