DSR

The DSR has been developed for use in partitions and doors where a reduction in noise transfer is required, as well as ventilation air transfer.

The DSR Transfer Grille is manufactured from high-quality aluminium extrusions with channel section cores forming a labyrinth airway lined internally with acoustic damping media. The cores are retained and matching adjustable rear border frame within a flanged frame which is fitted with a sealing gasket. DSRX units are supplied with fixed border and matching adjustable rear border frame.

DSR units will only provide acoustic isolation improvements over that of a clear aperture. DSR units may be used in series to increase transmission loss.
