"通气管系统" can be translated into English as "ventilation pipe system" or "breather pipe system".
Ventilation pipe system is a more general term that refers to a system of pipes used for ventilation purposes, which can include the removal of stale air, introduction of fresh air, or equalization of pressure, as in the case of some plumbing or storage tank systems.
Breather pipe system specifically emphasizes the function of allowing air to enter or exit a container or system to maintain pressure balance, which is a key aspect of certain types of vent pipes, such as those on storage tanks.
In the context of plumbing or storage systems, both terms can be appropriate, depending on the specific function and design of the system. If the focus is on maintaining pressure balance within a container, "breather pipe system" might be more precise. If the system is more broadly concerned with ventilation, "ventilation pipe system" would be the more suitable choice.
