Technical description

Design

The square, perforated supply air diffuser HAWK Ceiling consists of a diffuser backing box and a diffuser face. The diffuser face has perforations designed for managing high airflows. The diffuser face is hung on hinges on one side and secured by springs on the opposite side. This fastening system, called Quick Access, makes it simpler and quicker to open and close the diffuser face for installation, commissioning and cleaning.

The air diffuser is also available in a low version for installation in ceiling void where low installation height is required. The air diffuser is then supplied without any branch.

Material and surface treatment

The backing box and diffuser face are made of sheet steel. The connection branch is made of galvanized sheet steel. The interior and exterior surfaces of the air diffusers are painted.
