About This

• Efficient Airflow Ventilation – Designed with a convection shutter structure, these vents accelerate internal and external air exchange, improving indoor air quality, and creating a healthier environment for stored goods or living spaces
• Temperature & Humidity Control – Balances the temperature gradient between inside and outside. Prevents condensation build-up during winter and blocks heat waves in summer, helping maintain a constant-humidity cargo storage environment year-round
• Upgraded Structure – Heavy-duty stainless steel with a top guide eaves rainproof design. The shutters can be manually adjusted from 0°–90° for precise ventilation control according to different weather or storage needs
• Durable Materials for Harsh Environments – Made of corrosion-resistant galvanized steel with a finely perforated dustproof mesh screen, offering long-lasting performance even in salt spray, rain, or high-humidity conditions
• Flexible Multi-Point Installation – Suitable for side walls or end doors of 20ft/40ft containers. Recommended vent spacing is 2–3 meters, with 4–6 sets per container for optimal airflow and condensation prevention
