Air Supply Features of Bag Duct

Can the Bag Air Pipe Send Hot Air Down? Yes—Efficiently and Strategically

When it comes to heating large commercial or industrial spaces—such as warehouses, factories, gymnasiums, or high-ceilinged retail environments—the challenge isn’t just moving air—it’s directing it where it’s needed most. Unlike cooling, where cold air naturally sinks, warm air rises, making it difficult to distribute heat evenly across a room. This is where advanced fabric ducting systems like Saux’s bag air pipe come into play. Designed specifically for vertical air distribution, these systems ensure hot air reaches the occupied zone efficiently, reducing energy waste and improving thermal comfort.

Key Features:

• Jet Nozzle Technology: Saux holds an industry-exclusive patent on jet nozzle design that allows airflow to travel up to 7 meters vertically under 300 Pa pressure—a critical advantage in multi-story or high-clearance buildings.
• Seven Customizable Airflow Modes: From permeable diffusion to directional slit jets, each mode leverages induction principles to pull in surrounding air—up to 40 times the volume—creating powerful, efficient convection without mechanical blowers.
• Energy-Efficient Thermal Management: By delivering heated air directly to lower zones (where people are), these ducts eliminate stratification losses common in traditional HVAC setups, especially in spaces over 10 meters tall.
• High-Performance Materials: Made from flame-retardant, breathable textiles used in curtain manufacturing, the ducts offer durability, low maintenance, and excellent airflow control—ideal for both residential and industrial applications.

Saux's innovative approach goes beyond basic ventilation. The system’s core lies in intelligent airflow engineering—not just pushing air, but guiding it intelligently through dynamic pressure zones. Whether you're managing seasonal shifts between summer cooling and winter heating, or optimizing airflow in facilities with variable ceiling heights, this bag duct solution adapts seamlessly. It integrates easily with existing fan units, dampers, and controls, offering a scalable upgrade path for any facility manager looking to improve indoor climate performance.

Where It Works Best: Large open-plan areas such as aircraft hangars, distribution centers, sports arenas, exhibition halls, and manufacturing plants benefit significantly from this technology. Its ability to direct hot air downward ensures consistent temperatures at occupant level—even in structures exceeding 20 meters in height—making it a preferred choice for modern building management systems worldwide.

User Feedback Highlights: Facility managers report noticeable reductions in heating costs after installation, particularly in winter months when conventional ducts fail to deliver warmth effectively. Users appreciate the quiet operation, ease of cleaning, and visual integration with architectural interiors—no more bulky metal ductwork disrupting aesthetics or airflow patterns.

Frequently Asked Questions:

Q: Can this system really send hot air down in very tall spaces?

A: Yes—thanks to its patented jet nozzle design and induction-based airflow, the bag duct can reliably deliver heated air to lower zones even in spaces over 20 meters high, ensuring uniform thermal comfort.

Q: Is it suitable for both heating and cooling?

A: Absolutely. With seven different airflow modes—including permeable, slit, and jet configurations—it performs equally well in summer cooling and winter heating scenarios, adapting to seasonal needs without compromising efficiency.

Q: How does it compare to traditional metal ducts?

A: Unlike rigid metal ducts that create turbulence and dead zones, fabric ducts provide smooth, laminar flow while minimizing energy loss due to friction and poor air distribution. They also reduce noise and allow for better air mixing throughout the space.

This revolutionary fabric ventilation solution represents a new standard in air distribution—especially for challenging environments where traditional methods fall short. Whether you’re upgrading an existing system or designing a new one, Saux’s bag air pipe offers unmatched performance, flexibility, and value.
