Product Application : Vent Cap

Introduction

The lighting of an automobile is a crucial function of the vehicle for signaling, communication, and visibility. Depending on the function of the light (headlamps, tail lamps, fog lamps, turn signals, license plate lamps, etc.), however, they will produce different amounts of heat while in use. Most of these lights will also be in direct contact with the external environment, thus creating a need for a breathable product to equalize the pressure caused by temperature change to avoid seal breakage.
 
Fogging is another common issue for lights in automobiles. When the temperature drops below the dew point, water vapor in the air inside the light will condense into a liquid along the casing of the lights when the light is producing heat. The key to preventing this is to allow it to diffuse out of the enclosure. This involves one of the key parameters of the membrane: Moisture Vapor Transmission Rate (MVTR). Traditional breathable membrane suppliers can only provide membranes with one or two MVTRs, while IPRO offers membranes with multiple MVTR levels.
 
Vent caps are equipped with different ePTFE membranes to meet the airflow and humidity requirements of different gradients. The vent caps have a compact design that’s easier to install with a more stable protection level, making it ideal for headlamps.
 
IPRO has an experienced engineering team that can provide consulting services such as vent selection and design, right from the design stage of production.
 
Vent cap solutions provided by IPRO to the automotive industry has been recognized by many top OEMs and Tier 1 suppliers. It is conducive to good defogging and helping prolong the service life of the lamp, achieving a reduction in comprehensive costs.
