Plastic Breather Vent

PUW Plastic Air Vents are precision-engineered components designed to provide long-lasting protection for sensitive electronic devices and enclosures in harsh environments. By enabling air exchange while blocking water, dust, and contaminants, these venting solutions significantly enhance the durability, safety, and performance of outdoor and industrial electronics.

How It Works – The Venting Principle

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.

FAQ

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.
