The OB type opposed blade damper is offered as a standard method of flow control or equalisation and is suitable for use with the majority of grilles and diffusers within the Brooke Air range. Dampers are normally supplied ready fixed to the air terminal when specified, but can also be supplied separately for duct mounted applications.
OB Dampers are available in sizes ranging from 100mm x 50mm to a maximum of 1200mm x 450mm. Sizes larger than this are supplied in multiple sections.
