Perforated Plate Silencing Air Distribution Box For Fresh Air System

Perforated Plate Silencing Air Distribution Box — Acoustic Plenum for Fresh Air Systems

A galvanised silencing plenum box with an internal perforated silencing plate and sound-absorbing cotton. It does the job of a distribution box and a silencer at the same time: incoming air is split across the outlets while the perforated plate and acoustic lining absorb fan noise. Dimensions and outlet arrangements are customisable.
