Powertrain vent and breather for commercial vehicles, EVs, and internal combustion vehicles.
By controlling pressure and preventing the intrusion of water and contaminants, we protect the powertrain system and achieve durability that manufacturers can trust!
In both EV and conventional platforms, the powertrain housing undergoes repeated heating and cooling, experiencing continuous pressure fluctuations (pressure cycles). Without appropriate venting mechanisms, seals may fail, moisture may intrude, and electronic components or lubricants may degrade. Donaldson's vents prevent these issues. *For more details, please download the catalog or contact us.*
