Product Application : TPV Vent


In order to equalize pressure caused by temperature changes, ventilation holes need to be added to the motors, including the window motor and wiper motor that are in direct contact with external environment, as well as the starting motor and cooling motor in the engine compartment, which are exposed to long hours of severe temperature changes. However, ventilation holes weaken motors’ protection ability to a certain extent. Therefore, it is important to have venting products that not only have high IP rating but can also equalize pressure. The venting products applied to motors shall meet the following requirements:

  1. Large air permeability per unit area;
  2. High IP rating;
  3. Small footprint;
  4. Easy installation;
  5. Long service life.

IPRO TPV vent well adapts to complex working conditions due to its excellent mechanical properties and chemical stability. Compared with other forms of products, the membrane of TPV vent is protected by the injection molded parts from water droplets and harmful particles. IPRO TPV vent is a best choice for scenarios which require low IP rating and high reliability.

Key Features
  • Easy installation;
  • Press fit design and high fault tolerance;
  • 100% full inspection of WEP;
  • Large air permeability.
