摘要

The two-channel duct (1) is particularly intended for movement of air in air-conditioning installations. The duct is subdivided into two separate channels (3, 4) by a flexible, air-impermeable diaphragm (2) arranged in a medium plane of the duct and secured (5) to two opposite walls thereof. The diaphragm may consist of a sound-attenuating material.
