Abstract

An acoustic fresh air ventilator is formed in a box (1) in which one or more fans (8, 10) are located. The box is designed to be mounted to a wall (5) with an inlet and/or outlet ducting element (42, 44) extending from the box through the wall. The ducting elements are so arranged as to occupy a minimal space for reducing the size of the hole (70). The box is packed with acoustic packing materials suitably in pieces or bags (30, 32, 36, 38, 40). Conduits (20, 22, 24, 26) between the fan(s) and box sides are preferably formed by the packing material. The fan(s) is/are held in free floating suspension in the acoustic material.
