MILVENT® Powertrain Vents – Reliable Protection for Critical Components

• Enhanced Component Reliability:
  The MILVENT® membrane blocks water, dust, and road contaminants, while the pre-filter captures internal oil aerosols, extending the life of motors, differentials, and powertrain modules.
• Seal Integrity Under Extreme Conditions:
  Breathable membranes balance internal and external pressures, preventing leaks, deformation, and reducing maintenance costs even under high temperatures and vibrations.
• Compliance with OEM Standards:
  Fully meets global OEM requirements for water wading, fluid containment, and environmental resilience, adaptable to diverse regional regulations.
• Streamlined Development & Reduced Costs:
  Waterproof and contaminant-resistant design prevents vent-related test failures, shortening redesign cycles and accelerating product launch.
• Flexible Installation Options:
  Snap-fit and push-fit designs accommodate compact electric drives or traditional powertrain layouts, allowing optimal positioning and simplified maintenance.
• Full Lifecycle Technical Support:
  MILVENT provides global end-to-end guidance from product selection to installation and after-sales, ensuring smooth integration and reliable operation.
