Description
The American Louver Stratus Cone ceiling air Diffuser is a durable, lightweight alternative to traditional metal HVAC ceiling diffusers. It features a modern cone design and a smooth finish that looks like metal once installed.
Made from strong engineered polymers, this diffuser resists rust, corrosion, fading, and mildew. Unlike traditional metal diffusers, it will not need painting or repainting. Plus, its lightweight construction makes installation easier.
Designed for standard T-grid ceiling systems, the Stratus Cone Diffuser measures 23-3/4″ x 23-3/4″ and fits common commercial ceiling applications. It is available in 6″, 8″, 10″, 12″, and 14″ duct neck sizes.
The extra-tall 2-3/8″ neck also makes installation easier. In addition, molded-in duct tabs help connect the duct system.
