Diffusers and Return Grilles

American Louver offers a variety of diffuser and return grille variants tailored to meet diverse HVAC needs. The diffuser variants include the Cone and Plaque designs, each serving specific airflow distribution requirements. On the other hand, return grilles come in several variants, including filter, eggcrate, and perforated options, providing flexibility for different filtration and airflow management preferences.

More Durable

Constructed from engineered polymers, Stratus diffusers and return grilles guarantee longevity. They resist rust, corrosion, fading, and yellowing, while scratches remain inconspicuous. With no need for painting or repainting, they maintain their integrity over time and are resistant to bending. Additionally, their mildew-resistant properties ensure optimal hygiene.

Easy Installation

American Louver’s diffusers and return grilles are engineered with practicality and durability in mind. The diffusers feature an extra-tall neck for compatibility with standard duct and damper sizes, and their drop and damage-resistant design ensures longevity. Additionally, both the diffusers and return grilles are 50% lighter than metal alternatives and are crafted with rounded edges to prevent any risk of cut fingers or sharp edges. The return grilles are designed for effortless maintenance, with a hinged grille face that allows for quick and easy filter changes, ensuring optimal air quality. They are also easily removable for cleaning purposes and are compatible with commercial dishwashers, making upkeep a simple task.

Peak Performance

Despite their lightweight construction, Stratus diffusers and return grilles deliver airflow consistency comparable to metal counterparts. They possess antistatic properties and resist sweating, ensuring optimal airflow management. Additionally, they are flame-resistant, with fire-rated versions available for enhanced safety.


With a consistent smooth finish, Stratus diffusers and return grilles offer an attractive aesthetic for any space. They are more dimensionally stable than traditional metal diffusers and return grilles and are virtually indistinguishable from metal once installed, ensuring seamless integration with existing décor.
