SSC-AD - Slotted Swirl Diffuser
The SMARTEMP Slotted Swirl Diffuser, type SSC-AD, is a high induction radial slot ceiling swirl diffuser with manually adjustable discharge direction and pattern.
Supply air is discharged in a highly inductive swirling motion that strongly dilutes the supply air stream as it disperses into the space. Supply air direction is manually adjustable from a horizontal radial to downward vertical discharge. The air pattern may be manually set to 4-way, 3-way or 2-way blow.

Unique features include:
- Air pattern controller with pilot slot reduces pressure drop and increases capacity.
- Low pressure drop reduces fan energy.
- Air pattern vanes with off-set swivel maintain discharge velocity and throw for all discharge direction settings.
