The unique medium-pressure design ejects the poppet and cap to provide a larger opening for gas to escape during an emergency situation, boosting safety and reducing the risk of damage to other battery packs. It’s so efficient, it can reduce the number of vents required on a battery pack by up to 90%.

Donaldson has expanded its dual-stage battery pack vent line with the addition of the Dual-Stage Flex battery vent. The new battery vent enables pressure relief of automotive battery packs at lower pressures, helping support the life and reliability of electric vehicle (EV) batteries.

Donaldson now offers four powertrain vents (PTV) – the Screw-Fit and three Hose-Fit Powertrain Vents – that bring standardized assembly and long vent life to vehicles operating in harsh conditions.
