Durable Waterproof Inflatable Air Tent Portable Shelter with Easy Inflation

Featuring a fully prefabricated design with a clear span of 30 by 50 metres, the AirBrother Air-Supported Membrane Building delivers a safe, rapidly deployable enclosure for diverse indoor activities. An integrated pressurisation system, operating continuously at 200-300Pa, supports the entire membrane envelope without internal columns or traditional steel frameworks, offering an unobstructed, naturally illuminated volume that can be easily subdivided to suit specific usage requirements.

The dome utilizes high-grade architectural membrane materials, ensuring longevity and safety across extreme climates.

• 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. The system includes automatic pressure control, high-wind/snow mode adjustments, maximum safe pressure limits, overpressure relief devices, and low-pressure alarms.

To guarantee 100% operational safety, the system employs an N+1 redundant fan configuration. If any primary fan fails, backup units seamlessly maintain required pressure while triggering an automatic alarm.

Integrated with a comprehensive emergency plan:

• Backup power supply / generator interface
• UPS (Uninterruptible Power Supply) for control power
• Audible/visual alarms and clear personnel evacuation protocols

To prevent rapid pressure loss during entry, the main entrance utilizes advanced airlocks. Options include:

• Air-lock lobby / Buffer lobby
• Revolving doors / High-speed rolling doors / Double-door system

Reliable webbing and hanging points are reserved on the inner membrane to support lightweight equipment.

• Single-point load capacity: ≥ 25 kg
• Applications: LED lighting systems, lightweight HVAC ducts, cable management, and display installations

The exterior membrane (industrial white or light gray) balances natural lighting with heat reflection. Optional transparent or translucent daylighting strips can be integrated into the roof or upper sides for enhanced illumination.

Reserved interfaces (DN500-DN800 round, or 600×600mm / 800×800mm rectangular) are equipped with reinforced flanges and rainproof structures for easy connection to environmental control systems.

A minimum of 4 personnel/emergency exits are recommended, optimized for local fire evacuation and safety requirements.

• Anchoring System: Uses continuous foundation/ground beam systems, clamping grooves, and anchoring rails—strictly excluding temporary sandbags as the main method. The supplier provides detailed reaction force estimates and civil works preparation guides.
• Drainage System: Continuous perimeter drainage channels with drainage points set every 10-15 meters.
• Condensation Control: To prevent moisture in winter/humid environments, the structure supports double-layer membranes, thermal insulation liners, mechanical ventilation, and anti-dripping designs.

AirBrother ensures full compliance with international structural standards (EN 13782, EN 1991-1-4/1-3) and Chinese standards (CECS 158, T/CECS 1323, GB 50009, GB 55001).

• Design Documents: Floor plans, section drawings, module division plans, and anchoring layouts
• Technical Documents: Material data sheets, flame-retardant test reports, structural calculation summaries, and wind/snow load descriptions
• Quotation Documents: Itemized pricing for membrane modules, doors, fan/control systems, packaging, and optional extras (HVAC, etc.)
• Logistics Data: Packaging sizes, total gross weight, CBM volume, and container compatibility

• Maximum Space Efficiency: 1,500m² of 100% column-free space for flexible interior layouts
• Rapid Delivery: Modular prefabrication allows for significantly shortened construction periods and faster operational launch
• Superior Safety & Climate Adaptation: Dedicated solutions for extreme winds, snow, rain, and temperature fluctuations
• Low Maintenance & Expandability: Modular design allows easy partial maintenance. Interfaces are pre-reserved for future expansion, lighting, and brand displays

To finalize the tailored proposal, customers are advised to confirm:

1. Intended usage scenario and functional zoning
2. Final requirements for side and center height
3. Local maximum wind/snow load standards
4. Need for year-round HVAC, dehumidification, or heating systems
5. Fire evacuation approval regulations and target budget ranges
