Weather Resistant and Durable Inflatable Air Tent with Modular Assembly for Outdoor Events
The AirBrother 30×50m Air-Supported Membrane Building is a modular large-span prefabricated structure designed to deliver high safety standards, rapid installation, and versatile functionality across various indoor applications. Supported by a continuous internal air-pressure system of 200-300Pa, the structure requires no internal columns or conventional steel supports, resulting in a bright, open interior that can be flexibly zoned and adapted to suit varying operational needs.
| Building Size | Width 30m × Length 50m |
| Total Coverage | Approx. 1,500 m² |
| Side Clear Height | ≥ 4.5m (Customizable) |
| Center Peak Height | Recommended 9.0m - 12.0m |
| Modular Assembly | 4-5 Modules (Each ~10m - 12.5m long) |
| Main Entrance Opening | Width 4.5m - 5.0m × Height 4.2m - 4.5m |
- Membrane Material: Double-sided PVC-coated polyester fabric (Recommended 850-1100 g/m², thickness ~0.70-0.90mm)
- Target Service Life: ≥ 8-10 years
- Operating Temperature: -20°C to +60°C
- Flame-Retardant Rating: Meets EN 13501-1 B-s1,d0 / B-s2,d0 or GB 8624 B1 (B1级)
- Wind Resistance: Designed for operating wind speeds ≥ 28 m/s
- Snow Load Capacity: Roof snow load ≥ 0.50 kN/m² (with snow-pressure increase strategy)
Continuous fan-driven air supply maintains stable internal pressure with automatic control, high-wind/snow mode adjustments, and safety features.
Guarantees 100% operational safety with backup units that seamlessly maintain required pressure during primary fan failure.
Integrated emergency plan with backup power supply, UPS, and comprehensive alarm systems.
Advanced airlocks including air-lock lobby, revolving doors, and high-speed rolling doors to prevent pressure loss.
- Lighting & Hanging Interfaces: Reliable webbing and hanging points support lightweight equipment with single-point load capacity ≥ 25 kg
- Daylighting System: Industrial white or light gray exterior membrane with optional transparent/translucent roof strips
- HVAC & Fresh Air Interfaces: Reserved interfaces (DN500-DN800 round, or 600*600mm / 800*800mm rectangular) with reinforced flanges
- Emergency Exits: Minimum of 4 personnel/emergency exits optimized for fire evacuation requirements
- Anchoring System: Continuous foundation/ground beam systems with detailed reaction force estimates
- Drainage System: Continuous perimeter channels with drainage points every 10-15 meters
- Condensation Control: Double-layer membranes, thermal insulation liners, and mechanical ventilation systems
- Maximum Space Efficiency: 1,500m² of 100% column-free space for flexible interior layouts
- Rapid Delivery: Modular prefabrication allows significantly shortened construction periods
- Superior Safety & Climate Adaptation: Dedicated solutions for extreme winds, snow, rain, and temperature fluctuations
- Low Maintenance & Expandability: Modular design allows easy partial maintenance and future expansion
Ideal For: High-safety, large-span indoor venues including badminton/basketball courts, RC racing stadiums, exhibitions, and multi-purpose community centers.
To finalize the tailored proposal, please confirm:
- Intended usage scenario and functional zoning
- Final requirements for side and center height
- Local maximum wind/snow load standards
- Need for year-round HVAC, dehumidification, or heating systems
- Fire evacuation approval regulations and target budget ranges
