Intended for smartphones and portable electronic devices, PE3 Series provides typical airflow of 3,300 ml/min/cm³, equalizing internal pressure, minimizing stress on seals, and eliminating transducer bias. At same time, vents protect internal electronics by serving as barrier against liquid, dust, and dirt. Units are engineered with black oleophobic membrane and gray PET nonwoven backing to minimize contrast when mounted on exterior of dark electronic devices.
