Acoustic Air Transfer Grilles

Description

For air transfer applications, the channel section core with integral noise absorption material provides an effective solution when transfer ventilation is required but noise transmission through the grille needs to be reduced.

Construction

From extruded aluminium sections with Pyrosorb acoustic infill to all blades. Screw holes in the flanges are provided as standard as there is no access through the grille to facilitate secret fixing.
