Description

SST-POROUS® Screw-in Vents

SST-POROUS® Screw-in Vents protect the reliability and service life of sealed outdoor electronic devices in harsh environments. A threaded vent and sealing ring provide secure installation and long-term pressure equalization.

Key Features

Rapid pressure equalization: Bidirectional airflow reduces seal stress and helps limit condensation
Contamination barrier: Blocks solid and liquid ingress, even after immersion
Mechanical stability: Threaded installation stays secured in housings exposed to vibration and outdoor use
Easy installation: Low-profile screw-in design for tight spaces and standard threaded ports
Protection options: IP67 / IP68 / IP69K depending on series and housing design

Typical Applications

Battery enclosures
Sensors and industrial controls
Heavy-duty equipment
Lighting enclosures
Solar energy systems
Telecommunications equipment

AutomotiveAutomotive Electronics

Main Applications:

Vehicle Lighting Systems (Headlamps, Taillamps, Fog Lamps, etc.)
Powertrain Systems and Motor Controllers
New Energy Vehicle Battery Packs and Controllers
Electronic Control Units (ECU) and Sensors
Autonomous Driving Hardware (Radar, Cameras)

Challenges & Solutions Automotive electronic devices, especially in engine compartments or under high-vibration conditions, face extreme temperature fluctuations, high pressure differentials, oil contamination, and harsh road environments, which can lead to seal failure, condensation, and reduced component lifespan.

Spider Screw-in Vent utilizes high-performance ePTFE microporous membrane with a robust threaded structure. It provides reliable pressure equalization, excellent waterproof and dustproof protection up to IP67/IP68/IP69K levels, and strong mechanical fixation. The screw-in design ensures secure installation in high-vibration environments, reduces reliance on complex sealing structures, and lowers overall costs. Custom thread sizes, shapes, and breathability rates are available.

Outdoor Electronics

Main Applications:

Outdoor Lighting (Street Lights, Tunnel Lights, Garden Lights, High Pole Lights)
Photovoltaic Inverters
Communication Base Stations (5G/4G)
Security Monitoring Cameras
Outdoor Sensors and Intelligent Electric Bicycle Systems

Challenges & Solutions Outdoor electronic devices endure long-term exposure to rain, dust, salt spray, strong winds, and drastic temperature changes, often resulting in internal pressure buildup, seal aging, condensation, and premature equipment failure.

Spider Screw-in Vent employs high-performance ePTFE microporous membrane and a durable threaded body. It rapidly balances internal and external pressure, effectively prevents water and dust ingress, and achieves IP67/IP68/IP69K protection. The screw-in installation offers strong fixation and easy maintenance, simplifying enclosure design, reducing weight and cost, while enhancing long-term reliability. Customization in dimensions and performance is supported.

Outdoor Electronics

Main Applications:

Industrial Control Equipment
Outdoor Power Cabinets and Distribution Boxes
Agricultural and Construction Machinery Electronics
Marine and Port Equipment

Challenges & Solutions Industrial and harsh-environment equipment faces vibration, heavy dust, high-pressure water spray, and extreme weather, leading to frequent sealing failures and high maintenance costs.

Spider Screw-in Vent features a rugged screw-in design combined with ePTFE membrane, delivering superior pressure balancing, high waterproof/dustproof performance (IP67/IP68/IP69K), and excellent vibration resistance. Its robust mechanical connection ensures reliable long-term protection, reduces enclosure complexity, and helps lower total ownership costs. Fully customizable solutions are available.
