Precision Control in Any Space

Every uncontrolled leak in a duct run is a tax on every other component in the system. When airflow escapes before it reaches the canopy, the inline fan works harder, static pressure climbs, thermal gradients widen, and the environmental controller compensates in cycles that compound over time. Single-layer duct — the kind that ships as an afterthought with budget fan kits — tears at connection points, collapses under tight bends, and degrades silently behind walls and panels where no one checks until a crop cycle is already compromised. The enemy is not a single failure event; it is the slow, invisible erosion of atmospheric precision caused by infrastructure that was never built to hold.

After a properly specified duct run is in place, the atmospheric control system operates as designed. The inline fan moves its rated CFM to the intended destination. CO2 and humidity gradients stabilize because conditioned air is no longer bleeding into wall cavities or equipment bays. Maintenance cycles shift from reactive leak-tracing to scheduled inspection. The facility runs the environment it programmed — not a degraded approximation of it.

The AI-DTA4-8 achieves this through a four-layer construction architecture: an internal heavy-duty dual aluminum foil layer rated fire and flame resistant, a steel-wire spiral that maintains the duct's circular cross-section through bends and compressed routing without collapsing, and an outer dual PVC thermoplastic layer that shields the aluminum from cuts, abrasion, and mechanical contact while sealing against leakage. The 4 in. (10.2 cm) diameter and 96 in. (8 ft) length are sized for direct integration with standard 4-inch inline fan and carbon filter pairings. The tube can be shortened for custom-length applications, and two stainless steel 4-inch duct clamps are included for immediate, tool-ready installation. In practical terms, the AI-DTA4-8 delivers a sealed, fire-resistant, cut-resistant 8-foot duct segment at 4-inch diameter with four-layer wall construction and hardware included for a complete connection.

Where This Belongs (and Doesn't)

This ducting is a passive airflow component. It does not contain electrical wiring, control circuitry, or HVAC refrigerant lines. Installation must comply with applicable local building, fire, and mechanical codes. Consult a licensed mechanical contractor for installations integrated into permitted HVAC systems.

How It Works

The AI-DTA4-8 is built around a steel-wire spiral internal structure that functions as the duct's skeletal frame. This spiral maintains the 4 in. (10.2 cm) circular cross-section under compression, bending, and routing through tight or irregular spaces — preventing the flow restriction that occurs when unsupported flex duct collapses at bends. The spiral also enables the flexibility required to navigate around equipment, framing, and infrastructure without requiring rigid elbow fittings at every directional change.

Surrounding the steel-wire core, the internal layer consists of heavy-duty dual aluminum foil. This layer is the primary airflow surface and is rated fire and flame resistant, a material property that matters in installations adjacent to lighting fixtures, ballasts, or heating elements. Aluminum foil at this layer also provides a low-friction interior surface that minimizes turbulence and pressure drop across the duct run.

The outer layer is dual PVC thermoplastic. This is the layer that makes the AI-DTA4-8 a four-layer system rather than a standard two-layer flex duct. The PVC thermoplastic serves two functions: it mechanically protects the aluminum foil from cuts, punctures, and abrasion during installation and in service, and it provides a secondary seal against air leakage at any point where the aluminum layer might be compromised. The result is a duct wall that resists failure from both the inside (pressure, heat) and the outside (mechanical contact, installation stress).

The 96 in. (8 ft) length is the standard run for connecting a 4-inch inline fan to a carbon filter or exterior exhaust point in a single uninterrupted segment, eliminating the need for mid-run couplers that introduce additional leak points. The duct can be shortened with standard sheet metal shears for custom-length applications. Two stainless steel 4-inch duct clamps are included, providing the hardware necessary to complete both connection points without a separate hardware order. In practical terms, the AI-DTA4-8 delivers a four-layer, fire-resistant, cut-resistant 8-foot duct run at 4 in. (10.2 cm) diameter with steel-wire spiral support and two stainless steel clamps included for immediate installation.

Commercial Assurance

System Integration

• Inline Fan Pairing: Sized for direct connection to AC Infinity CLOUDLINE and compatible 4-inch inline fan series without reducer fittings.
• Carbon Filter Connection: Mates directly to standard 4-inch carbon filter flanges; included stainless steel clamps complete both connection points.
• Controller Ecosystem Compatibility: Functions as the passive airflow conduit within AC Infinity UIS-compatible atmospheric control ecosystems — duct integrity is a prerequisite for accurate CFM delivery to controller-managed environments.
• Length Adjustment: Can be shortened with sheet metal shears for custom-length runs; cut end should be secured with an included clamp to maintain seal integrity.
• Multi-Zone Routing: Steel-wire spiral flexibility supports routing through framing, equipment bays, and tight corners without rigid elbow fittings, reducing total connection hardware in multi-zone atmospheric control installations.

Operator Field Notes

• Clamp First, Then Seal: The two included stainless steel 4-inch clamps are sized for the AI-DTA4-8 flanges — install both clamps before powering the inline fan to confirm seal integrity under operating pressure.
• Shorten Before Routing: If the run requires less than 96 in., cut to length before routing through tight spaces — attempting to trim after routing risks kinking the steel-wire spiral at the cut point.
• Bend Radius Discipline: The steel-wire spiral maintains cross-section through moderate bends, but sharp 90-degree bends at short radius will restrict airflow regardless of duct wall construction — use a rigid elbow fitting for angles exceeding approximately 45 degrees in a single bend.
• Fire-Resistance Context: The internal aluminum foil layer is rated fire and flame resistant, not fireproof. This rating is relevant for proximity to heat-generating equipment, not for installation in fire-rated wall assemblies without additional code-compliant fire stopping.
• Outer Layer Inspection: The PVC thermoplastic outer layer is the primary indicator of duct condition — inspect for cuts, abrasion, or deformation at connection points during scheduled maintenance cycles. Outer layer damage that exposes the aluminum foil layer is a replacement trigger, not a patch candidate.
• Length Inheritance: When replacing a run, measure the existing duct length before ordering — the AI-DTA4-8 ships at 96 in. and can be shortened, but cannot be extended without a coupler that introduces an additional connection point.
