Precision Control in Any Space

Every uncontrolled air leak in a cultivation facility is a direct tax on your environmental precision — and it compounds silently. Substandard flex duct collapses under sustained negative pressure, develops micro-tears at bend points, and allows conditioned air to bleed into wall cavities and interstitial spaces before it ever reaches the canopy. The result is a VPD profile that drifts zone to zone, a dehumidification system working harder than its rated capacity, and an atmospheric control strategy that looks correct on paper but fails at the plant level. Guesswork fills the gap where engineered infrastructure should be, and every hour the system runs in that condition is an hour of yield potential that cannot be recovered.

When the duct infrastructure is sealed and structurally sound, the atmospheric control ecosystem performs as designed. Inline fans move their rated CFM without compensating for leakage losses. Temperature and humidity gradients flatten across the canopy zone. CO2 enrichment stays within the cultivation envelope instead of migrating through failed duct seams. Scheduled climate transitions execute on time because the delivery pathway is not introducing uncontrolled variables. The facility operates as a closed, predictable system — and predictable systems produce consistent harvests.

The mechanism behind that reliability is a four-layer wall construction that addresses the two primary failure modes of flex duct: structural collapse and surface penetration. The inner assembly consists of heavy-duty dual aluminum foil rated fire/flame resistant, maintaining bore geometry under both positive and negative pressure. The outer assembly is dual PVC thermoplastic, which absorbs abrasion, resists cuts, and stops leakage at the wall surface before it can reach the foil layers. A continuous steel-wire spiral runs the full 300 in. (25 ft) length, preventing kinking and collapse at bends — the exact failure point where single-layer duct loses structural integrity. The tube can be shortened for specific run lengths without compromising the wall structure, and the 10 in. (25.4 cm) diameter is sized for high-volume inline fan circuits where airflow capacity is the governing design constraint. In practical terms, the AC Infinity Flexible Ducting 10" delivers a sealed, fire/flame-resistant 10 in. (25.4 cm) airflow conduit across a 300 in. (25 ft) run length with four-layer wall construction and continuous steel-wire spiral support.

Where This Belongs (and Doesn't)

This ducting is a passive airflow conduit. It does not generate, filter, or condition air. It is not a substitute for rated HVAC ductwork in pressurized plenum applications governed by local mechanical codes. Consult a licensed mechanical contractor for installations subject to building permit requirements.

How It Works

The four-layer wall architecture of the AI-DTA10 is a sequential defense system against the two conditions that cause flex duct to fail in service: mechanical penetration from the outside and structural collapse from pressure differentials on the inside. Starting from the bore outward: the first layer is heavy-duty aluminum foil — the primary airflow surface, reflective, and fire/flame resistant. The second layer is a second aluminum foil laminate, adding redundancy against pinhole formation and reinforcing the fire resistance rating. These two inner layers form the sealed airflow channel. The third and fourth layers are dual PVC thermoplastic — the outer protective shell that absorbs contact abrasion, resists cutting from duct clamp edges and structural contact points, and provides the leak-stop barrier that prevents any breach of the foil layers from becoming an open air leak into the surrounding space.

Running through the full 300 in. (25 ft) length is a continuous steel-wire spiral embedded between the inner and outer layer assemblies. This spiral is the structural element that maintains the 10 in. (25.4 cm) bore diameter under negative pressure — the operating condition of every inline fan exhaust circuit. Without it, flex duct collapses at bends and reduces effective bore area, increasing static pressure and reducing fan output below rated CFM. With it, the duct holds its geometry through tight routing paths and hard-to-reach installation points, which is the specific condition the steel-wire spiral is engineered to address. The tube can be cut to shorter run lengths for applications where the full 25 ft is not required, and the included two stainless steel 10" duct clamps provide the termination hardware needed for a sealed connection at both ends. In practical terms, the AC Infinity Flexible Ducting 10" maintains a sealed 10 in. (25.4 cm) bore across a 300 in. (25 ft) run via four-layer wall construction and continuous steel-wire spiral support, with two stainless steel duct clamps included for termination.

System Integration

• Inline Fan Pairing: The 10 in. (25.4 cm) diameter is sized for high-volume inline centrifugal fans. Match duct diameter to fan outlet diameter to eliminate reducer losses and maintain rated CFM delivery.
• Carbon Filter Connection: Use the included stainless steel duct clamps to terminate the duct at carbon filter flanges. Clamp-sealed connections eliminate bypass air that degrades odor control performance.
• Atmospheric Control Ecosystem: In facilities running AC Infinity UIS-compatible controllers, sealed duct infrastructure is the physical layer that allows fan speed modulation to produce measurable atmospheric outcomes — VPD response, CO2 retention, and temperature differential control all depend on duct integrity.
• Run Length Management: The 25 ft length can be shortened by cutting the tube at any point. Retain the steel-wire spiral at the cut end and secure with a duct clamp to maintain bore integrity at the new termination.
• Multi-Zone Routing: The steel-wire spiral allows the duct to navigate hard-to-reach installation paths — behind equipment racks, through wall penetrations, and around structural obstructions — without kinking or bore collapse.

Operator Field Notes

• Bore Integrity at Bends: The steel-wire spiral maintains the 10 in. (25.4 cm) bore diameter through bends. Do not exceed the minimum bend radius recommended by AC Infinity — over-bending compresses the spiral and reduces effective bore area even when the outer surface appears intact.
• Clamp Torque: The included stainless steel duct clamps should be tightened to firm contact with the outer PVC layer — not over-torqued. Excessive clamp force can deform the thermoplastic outer layer at the termination point and create a leak path rather than prevent one.
• Shortening Protocol: When cutting the duct to a shorter run length, use aviation snips or a sharp utility knife. After cutting, re-seat the steel-wire spiral at the new cut end and apply a duct clamp before connecting to the fan or filter flange.
• Thermal Cycling: The dual aluminum foil inner layers handle the thermal cycling typical of inline fan exhaust circuits. Inspect clamp connections at the start of each cultivation cycle — thermal expansion and contraction can loosen clamps over time in high-duty-cycle installations.
• Storage: Store compressed or coiled at the minimum diameter that does not permanently deform the steel-wire spiral. Permanent kinks in the spiral cannot be reversed and will create a static pressure restriction at that point in the run.
• Compatibility Check: Confirm fan outlet and filter flange diameters are 10 in. before ordering. Reducer couplings introduce static pressure losses that reduce effective fan output — size-matched connections are the correct specification.
