SunnCamp Swift Air SC 390 – Inflatable Caravan Porch Awning
Extra-Wide Touring Air Awning • Spacious Living Area • Premium Inflatable Comfort
390cm Wide Design | Air Volution Multi Inflation Technology | ACE-TECH 150D Fabric | Enhanced Storm Stability Package
The Swift Air SC 390 is designed for touring caravanners who require a larger outdoor living area while maintaining the convenience of a lightweight inflatable awning. With its generous 390cm width and practical 240cm depth, it creates a spacious extension to your caravan, perfect for relaxing, dining, storing equipment, or entertaining guests on-site.
Built using SunnCamp’s trusted Air Volution Multi Inflation Technology, the awning inflates quickly and efficiently, significantly reducing pitching time compared to traditional pole systems. The durable ACE-TECH 150D fabric offers reliable waterproof and fire-retardant protection while remaining lightweight and easy to manage during transport and storage.
Large panoramic windows allow natural light to flood the interior, while the secondary mesh side panels improve airflow and help reduce condensation. The front door can be rolled up or converted into a canopy configuration (optional poles required), creating an open and inviting outdoor living space.
Unlike the smaller Swift Air SC models, the 390 benefits from three Air Storm Bars and an additional Vertical Storm Pole, providing enhanced structural stability and confidence during challenging weather conditions. The awning is also compatible with the optional Buckle-Fit Sun Canopy range, allowing you to further extend your sheltered outdoor area.
