Con guration
The SRA di user is a smooth di user with rectangular sections on which slots are mounted
length. The number of slots is determined by air ow quantity and duct dimensions. The
slots contain 100 mm long ABS eccentric rollers or ABS nozzle rollers (black, or white). The
eccentric rollers are provided with alphanumeric guides which allow air ow pattern
adjustment across a 180°range (see page 9).
Passive ducts without slots are available in the same dimensions as the active SRAs in order
to ensure duct network uniformity.
The SRA di user is available in many dimensions (see our catalogue, page 12).
