This is a 12x12-inch linear slot diffuser made of solid extruded aluminum with an electrostatic white finish. It works as both a supply and return vent in ceilings, walls or floors, and its directional dampers throw air in a 90-degree spread or to one side. Airflow Sciences tested it to ASHRAE-70 and ISO 3741 standards, with 293 CFM at 9.8 ft/s effective velocity. It suits remodelers and builders who want a clean architectural look instead of a stamped steel grille, though it is a non-filter model and costs more than basic vents.

This is a 12x12 white modern AC vent cover, also known as a linear slot diffuser. It has a clean, architectural look and is meant to be decorative rather than structural. It can be used as a supply vent cover or a return vent cover in ceilings, walls and floors.
The cover is made from solid extruded aluminum with welding and finished in electrostatic paint. The paint resists dust, which makes it easy to clean. Decorative directional dampers send air out in a 90-degree spread, and they can be adjusted to one side or the other.
On a floor, the cover is not designed to support weight, and adding weight is not recommended. When used as a return vent cover, set it to the full open position or remove the directional dampers. It is a non-filter model. Its performance was tested to ASHRAE-70 and ANSI S12.51/ISO 3741 standards by Airflow Sciences Corporation.
