A circular diffuser distributes supply air in a symmetrical radial pattern from a round duct connection, without needing a square-to-round transition. Specs, applications, and how to specify one.

A round plaque diffuser combines the plaque diffuser's flush, no-pattern face with a circular shape instead of square. Specs, applications, and how to specify one.

A plaque diffuser uses a flat, solid face plate rather than a grid or cone pattern, for a minimal, architectural ceiling look. Specs, applications, and how to specify one.

A grid diffuser uses a flat lattice-style face, sized to fit standard suspended ceiling grid modules. How it differs from a square diffuser and egg crate grille, plus how to specify one.

A linear curved grille follows a curved wall or ceiling line instead of running straight, keeping the linear look on non-flat surfaces. Specs, applications, and how to specify one.

A slot diffuser actively distributes supply air across a room through an engineered throw pattern, unlike a slot grille used mainly for return or exhaust. Specs, applications, and how to specify one.

A non-vision grille is built to block direct sightlines through the opening entirely, for locations where seeing through isn't acceptable. Specs, applications, and how to specify one.

A double louver grille uses two rows of angled blades for extra airflow direction control and a deeper sightline block. Specs, applications, and how to specify one.

A decorative grille uses an ornamental pattern rather than plain blades or holes, for openings where appearance matters most. Specs, applications, and how to specify one.

An egg crate grille uses an open square-cell grid for high free area airflow, most often on return and exhaust air openings. Specs, applications, and how to specify one.
