Precision Control in Any Space

Every uncontrolled leak in a ventilation run is a tax on every other system in the facility. Pressure drops silently — fans work harder, temperature gradients widen, humidity stratifies, and the environmental targets you set at the controller never actually reach the canopy. Standard flex duct is the weak link operators tolerate because they assume all duct is equivalent. It is not. Single-wall and low-grade dual-layer constructions develop micro-tears at flex points, delaminate under sustained negative pressure, and surrender to the mechanical abrasion of installation and repositioning. The result is a system that fights you: you dial in the numbers, and the infrastructure bleeds them out before they arrive.

After deployment, the picture changes. Airflow reaches its destination at the volume and velocity the fan was sized to deliver. Temperature uniformity across the canopy tightens because the atmospheric control system is no longer compensating for infrastructure losses. Scheduled ventilation cycles execute as programmed — not as approximated by a leaking run. Maintenance windows shrink because the duct itself stops being a failure point. The facility operates the way it was designed to operate, and the operator stops troubleshooting infrastructure and starts managing outcomes.

The mechanism behind that reliability is a four-layer wall construction engineered specifically for sustained mechanical and thermal stress. The innermost layer is heavy-duty dual aluminum foil rated as fire and flame resistant, maintaining structural integrity under elevated exhaust temperatures. Surrounding that is a steel-wire spiral structure that prevents collapse under negative pressure and maintains the duct's circular cross-section through bends and flex points. The outer shell is dual PVC thermoplastic — two layers of cut and tear resistance that protect the aluminum core from installation damage, abrasion against framing, and incidental contact with tools and hardware. The full assembly spans 25 feet at a 12-inch diameter, ships with two stainless steel 12" duct clamps for immediate sealed connection, and carries a 2-year warranty. In practical terms, the AI-DTA12 delivers a sealed, pressure-stable 12-inch airflow pathway across 25 feet with a four-layer wall rated for fire resistance, cut resistance, and sustained negative-pressure operation.

Where This Belongs (and Doesn't)

This ducting is designed for low-pressure ventilation and exhaust applications. It is not rated for high-pressure forced-air HVAC supply plenums, gas conveyance, or any application requiring rigid duct certification. Consult a licensed mechanical contractor for installations subject to local building code or fire suppression system integration requirements.

How It Works

The AI-DTA12 is built around a four-layer wall architecture that addresses the three primary failure modes of standard flex duct: internal combustion risk, structural collapse under negative pressure, and external mechanical damage. Each layer performs a discrete protective function, and the four layers operate as an integrated assembly rather than independent materials stacked together.

The innermost layer is heavy-duty dual aluminum foil. Aluminum foil at this gauge provides fire and flame resistance, ensuring that the duct maintains structural integrity in exhaust applications where elevated temperatures from lighting, equipment, or process heat are present. Directly outside the aluminum foil core, a steel-wire spiral structure runs the full 25-foot length of the duct. This wire helix is the structural backbone of the assembly — it resists radial compression under negative pressure, prevents the duct from kinking at bend points, and maintains the full 12-inch circular cross-section that the connected fan was sized to move air through. A collapsed or kinked duct cross-section reduces effective airflow area and forces the fan to operate outside its rated performance curve.

The outer two layers are dual PVC thermoplastic. PVC at this application provides cut resistance against installation contact with framing hardware, fasteners, and tools, and tear resistance against the mechanical stress of repositioning and routing through tight spaces. The dual-layer outer construction means that a surface abrasion that compromises the first PVC layer does not immediately expose the aluminum core to further damage or create a leak path. The full assembly is field-trimmable — the tube can be shortened for specific run lengths without compromising the wall structure at the cut end. Two stainless steel 12" duct clamps are included for immediate sealed connection at both termination points. In practical terms, the AI-DTA12 delivers a 12-inch, 25-foot flexible airflow pathway with a four-layer wall rated for fire resistance, negative-pressure structural stability, and dual-layer cut and tear protection, ready for immediate installation with included stainless steel clamps.

Commercial Assurance

System Integration

• Inline and Centrifugal Duct Fans: The 12-inch diameter is sized for direct connection to AC Infinity CLOUDLINE and CLOUDREV series 12-inch inline fans, as well as compatible third-party centrifugal and mixed-flow duct fans. The included stainless steel clamps provide a sealed, slip-resistant connection at both fan collar and termination point.
• Carbon Filter Exhaust Runs: Routes filtered exhaust from 12-inch carbon scrubbers to exterior discharge points. The fire-resistant inner layer is appropriate for exhaust runs where heat from adjacent lighting or ballast equipment may elevate duct surface temperatures.
• Atmospheric Control Ecosystems: Functions as the physical airflow pathway in automated atmospheric control deployments where fan speed, cycle timing, and environmental targets are managed by a controller. Duct integrity is a prerequisite for controller accuracy — a leaking run introduces uncontrolled air exchange that no controller algorithm can fully compensate for.
• Multi-Zone Distribution: The 25-foot run length and field-trimmable construction allow a single unit to serve multiple connection points in a zoned ventilation layout, reducing the number of duct segments and connection joints required.
• AV and Equipment Cooling Runs: Compatible with rack and cabinet cooling configurations where a 12-inch supply or exhaust run is required and rigid duct cannot be routed due to spatial constraints.

Operator Field Notes

• Clamp Before You Pressurize: Both included stainless steel 12" duct clamps should be seated and tightened before the connected fan is powered. A hand-tight slip fit will hold under static conditions but will migrate under sustained airflow pressure, creating a leak at the collar joint.
• Trim to Length Before Installation: The duct can be shortened for specific run lengths. Cut with aviation snips or a utility knife at a marked point, then fold and secure the cut end before clamping. Do not leave a raw cut end unsecured against a fan collar — the wire spiral at the cut edge can abrade the fan housing over time.
• Minimum Bend Radius: The steel-wire spiral maintains cross-section through moderate bends, but sharp 90-degree bends at short radius will compress the wire helix and reduce effective airflow area. Route with gradual curves where possible, or use a rigid elbow fitting at hard corners.
• Inspect Outer Layer at Installation: The dual PVC outer layer is the first line of defense against abrasion damage. Inspect the full run length after routing for any contact points with sharp framing edges or fastener heads. Pad or reroute contact points before final installation to prevent progressive wear through the outer layer.
• Negative Pressure Confirmation: After installation, run the connected fan at full speed and walk the full duct run with your hand near all connection points and along the duct body. Any detectable airflow at a point other than the intended discharge indicates a leak that needs to be addressed before the run is considered sealed.
• Storage Between Deployments: Store coiled at a diameter no tighter than the duct's natural resting coil. Forcing the duct into a tight coil for storage can stress the wire spiral at the inner radius and create a permanent kink point that reduces cross-section in that location during the next deployment.
