Electronic enclosures often undergo internal pressure fluctuations due to temperature changes or altitude differences. Without proper venting, this can cause:
Seal deformation and water/dust intrusion
Condensation inside enclosures
Reduced reliability of internal components
PUW vents incorporate a microporous PTFE membrane that enables airflow while blocking liquids, dust, and contaminants. This ensures pressure equalization, dry internal conditions, and extended equipment life.
High Weather Resistance
UV-resistant and anti-aging materials ensure stable performance in rain, heat, snow, and sunlight.
Robust Structural Design
Reinforced plastic construction withstands vibration, impact, and mechanical stress — ideal for automotive and industrial applications.
Long Service Life
Built for durability and reliability. With advanced sealing technology, PUW vents reduce maintenance needs and equipment failures.
OEM/ODM Customization
Supports customized designs for different thread types, plastic grades, sizes, and logo printing. Adaptable to unique product requirements.
PUW Plastic Air Vents are trusted across multiple industries where environmental sealing and pressure equalization are critical:
Automotive Electronics
Control modules, battery systems, headlights, ADAS cameras. Protect against pressure buildup, moisture, and road chemicals.
Telecommunication Equipment
Outdoor base stations, antennas, routers, signal amplifiers. Maintain stable internal pressure while preventing condensation.
Smart Home Devices
Outdoor security cameras, doorbells, smart locks. Enhanced reliability in all-weather conditions.
LED Lighting Systems
Street lights, tunnel lights, solar-powered lights. Venting improves heat dissipation and prevents lens fogging.
Industrial Control Boxes
Sensor housings, junction boxes, power inverters. Prevent corrosion and overheating in harsh working environments.
Surveillance & Monitoring Systems
Enclosures for outdoor CCTV, wildlife cameras, environmental sensors. Critical for clear imaging and uninterrupted monitoring.

1. What are PUW Plastic Air Vents used for?
PUW plastic air vents are designed to protect electronic enclosures from water, dust, pressure buildup, and temperature-related damage. They allow air and gases to pass through while preventing contaminants from entering, ensuring internal components stay dry, balanced, and fully functional.
2. How do PUW vents work?
The vents use a microporous PTFE membrane that equalizes pressure caused by temperature or altitude changes. Air can pass through freely, but water, oil, dust, and other particles are blocked — preventing seal failure, condensation, and internal damage.
3. What industries are these vents suitable for?
PUW vents are widely used in:
Outdoor LED lighting systems
Automotive electronics
Solar photovoltaic equipment
Communication devices
Security cameras and enclosures
General industrial and electrical applications
4. What IP ratings are available?
PUW vents offer IP67, IP68, and IP6K9K protection levels — ensuring excellent water and dust resistance, even in high-pressure wash-down or submerged environments.
5. What is the operating temperature range?
The vents perform reliably in extreme conditions, with an operating temperature range from -40°C to 115°C.
6. Are the vents UV and weather resistant?
Yes. The PC (polycarbonate) body is UV-resistant and anti-aging, making it ideal for long-term outdoor use under sun, rain, or wind.
