Limitless Modular Scalability
Start with a single 5.4-meter arch and seamlessly connect up to 6 units to create a cavernous, 32.4-meter continuous hall that perfectly scales to your exact requirements.
Rapid, Zero-Metal Commercial Setup
A single 8.2-meter wide arch inflates to full rigidity in just 16 minutes. No heavy steel trusses, complex crane rigging, or specialized construction crews required.
Versatile Hard-Surface Anchoring
The robust black base skirt and included water-ballast bags allow secure anchoring on asphalt parking lots, concrete plazas, or indoor exhibition halls without surface damage.
Professional Architectural Aesthetics
The crisp white shell combined with repeating arch silhouettes creates a highly polished, contemporary, and elegant visual presence that elevates brand activations.
100% Clear-Span Interior Corridor
With zero intrusive internal support legs, the tunnel offers an unobstructed, continuous corridor perfect for drive-through displays, rowed seating, or sprawling exhibition layouts.

How does the connection system between different arches ensure water and wind tightness?
The connection point uses a three-layer sealing process: a heavy-duty industrial zipper provides the primary structural link, an overlapping PVC apron flap covers the zipper track, and a final set of tension straps compresses the seam against the air-frame. This ensures a completely watertight, airtight bond between modules, even during heavy rain.
What is the function of the black base skirt on the bottom of the pavilion?
The heavy-duty black skirt serves three critical functions. First, it acts as an abrasive shield, protecting the fragile white fabric from scraping against rough concrete, gravel, or asphalt. Second, it houses reinforced loops specifically for attaching the heavy water-ballast bags. Third, it provides a low-profile, dark visual border that anchors the white structure visually to the ground.
Do the continuous arches require a blower to run the entire time?
No. Like all HAFE products, this system utilizes a closed-loop inflation mechanism. You inflate the multi-chamber frame to the recommended 155–185 Pa pressure, seal the heavy-duty air-lock valves, and detach the blower. The entire connected 32-meter tunnel complex will remain completely rigid and self-supporting for days without continuous electrical power.
How do the water-ballast bags work on an asphalt parking lot?
The water-ballast bags are made from heavy-duty, watertight PVC. You simply fill them with water on-site (using a hose or water pump) and securely strap them around the heavy-duty anchor loops hidden inside the black base skirt. The combined weight of the water-filled bags provides immense downward pressure, preventing the tent from shifting or lifting, all without needing to drill a single hole into the asphalt surface.
Can I fully enclose the open arches if the weather turns bad?
Yes. Each module is supplied with optional detachable PVC end-walls and side panels. These panel sets are designed with a matching arch silhouette and can be quickly zipped into the front and rear archways, instantly converting the open-air tunnel into a fully sealed, waterproof, and wind-tight enclosed hall.
