Air Distribution Grilles, Louvres and Diffusers

Circular Ceiling Diffusers

Circular ceiling diffuser, circular cone ceiling diffuser or duct mounted diffusers, are capable of a high aspiration rate and have the capacity to handle large volumes of air at relatively low sound levels for supply and extract applications, making these diffusers particularly useful for installation in open plan areas such as auditoriums, airport lobbies, supermarkets and factories.

Four separate model types are available, Model OD-1, Model OD-2, Model OD-10 and Model DE.

Model OD-1 is a fixed horizontal air pattern diffuser having flush inner cones. Model OD-2 is a fixed horizontal air pattern diffuser with projecting inner cones. Model OD-10 has an adjustable flat central disc for horizontal throw or vertical discharge.

Models OD-1, OD-2 are fabricated from steel whilst the Model OD-10 is constructed from a combination of both aluminium and steel. All model types are finished in White polyester powder as standard, other colours are available as an optional extra.

Model DE has a versatile inner cone providing 5 adjustment positions, where the air pattern can be altered from horizontal throw to vertical projection. In addition the inner cone is easily removed for access or cleaning.
