Conducto flexible de cuatro capas AC Infinity | 25 pies de largo | 4 pulgadas

Precision Control in Any Space

Every atmospheric control system has a weakest link, and in most installations that link is the duct wall. Single-layer foil collapses under sustained negative pressure, develops pinhole leaks at flex points, and tears at the first contact with a sharp edge or fastener. Those failures are invisible until the environmental data tells you something is wrong — by which point the variance has already compounded. Guesswork and equipment that fights you are not abstract problems; they are the direct result of infrastructure that was never built to hold pressure across a full production cycle.

After deployment, the airflow path becomes a fixed, predictable variable. The duct holds its geometry under flex, seals at every clamp point, and routes from fan outlet to exhaust port without pressure loss at the wall. Atmospheric control becomes a function of fan selection and controller programming — not a daily audit of duct integrity. The installation goes in once, routes through tight spaces without kinking, and stays there.

The mechanism is a four-layer wall construction: an inner dual aluminum foil layer rated for fire and flame resistance, surrounded by a dual PVC thermoplastic outer layer that absorbs cuts and abrasion while blocking leakage at the surface. A steel-wire spiral runs the full internal length, maintaining the duct's circular cross-section under compression and flex so airflow area does not collapse when the duct is routed around corners or through confined pathways. The 4-inch (10.2 cm) diameter is dimensionally matched to standard inline duct fan collars and carbon filter flanges, and the 300-inch (25 ft) total length provides sufficient run for most single-zone installations without a splice. In practical terms, the AI-DTA4 delivers a sealed, four-layer airflow conduit across a 25-foot run at 4-inch diameter, with two stainless steel clamps included for immediate termination at both ends.

Where This Belongs (and Doesn't)

This ducting is a passive airflow conduit. It does not generate, filter, or condition air. All electrical connections, fan mounting, and filter integration must be performed in accordance with the equipment manufacturer's specifications and applicable local mechanical and electrical codes. Cannafull Spectrum Solutions does not provide installation services.

How It Works

The AI-DTA4 wall is built in four discrete layers, each performing a separate structural function. The innermost layer is heavy-duty dual aluminum foil — the primary airflow surface, rated for fire and flame resistance, and responsible for maintaining a smooth bore that minimizes turbulence and friction loss along the run. Surrounding the foil core is a dual PVC thermoplastic outer layer that serves as the mechanical protection shell: it absorbs contact with sharp edges, fasteners, and rough surfaces that would puncture single-layer foil, and it seals the outer surface against leakage even when the inner foil is flexed repeatedly.

Running the full internal length of the duct is a steel-wire spiral structure. This is the element that separates flexible ducting that holds its shape from flexible ducting that collapses. The spiral maintains the circular cross-section of the 4-inch (10.2 cm) bore under compression, bending, and sustained negative pressure from an inline fan. When the duct is routed through a tight corner or compressed against a wall, the wire spiral prevents the bore from flattening — which would reduce effective airflow area and increase system resistance against the fan.

The full 300-inch (25 ft) length is field-cuttable. The tube can be shortened with standard sheet metal shears or a utility knife to fit the exact run length required, eliminating excess slack that would otherwise create low points where condensate accumulates or kinks that restrict airflow. Two stainless steel 4-inch duct clamps are included, providing immediate mechanical termination at both the fan collar and the filter flange without requiring a separate hardware order. In practical terms, the AI-DTA4 delivers a four-layer, steel-wire-reinforced airflow conduit across a 300-inch run at 4 in. (10.2 cm) diameter, field-cuttable to length, with two stainless steel clamps included for sealed termination at both connection points.

Commercial Assurance

• Authorized Distribution: Cannafull Spectrum Solutions is a factory-authorized dealer for AC Infinity Inc. products. SKU AI-DTA4 ships as new, factory-sealed stock.
• Warranty: Warranty terms are governed by AC Infinity Inc. manufacturer policy. Warranty period is not specified in available source data — contact Cannafull Spectrum Solutions at support@cannafullspec.com for current warranty documentation before purchase if this is a decision factor.
• MAP Compliance: This product is sold at or above the manufacturer's advertised price of $21.99 (SKU AI-DTA4).
• Counterfeit Risk: AC Infinity products purchased outside authorized channels may be counterfeit or gray-market stock without valid warranty coverage. Purchase through authorized dealers only.
• Support: Pre-sale technical questions and post-sale support are available at support@cannafullspec.com.

System Integration

• Inline Fan Compatibility: The 4-inch diameter collar is dimensionally matched to 4-inch inline duct fans including the AC Infinity Cloudline S4, which operates at 100-240V AC / 50-60Hz, draws a maximum of 28W (21W average), pulls 1.2A, and connects via US Plug (NEMA 1-15 Type-A) with dual ball bearings for low-vibration operation.
• Carbon Filter Integration: Compatible with 4-inch air carbon filters (e.g., AC-DCF4). Secure the duct to the filter flange using the included stainless steel worm gear-style clamps for a sealed, leak-free connection.
• Clamp Termination: Both included stainless steel 4-inch duct clamps are sized for direct installation at fan collar and filter flange termination points — no additional hardware required for a two-point installation.
• Field Modification: The duct can be shortened by cutting to the required run length. Use sheet metal shears or a sharp utility knife. Cut ends should be de-burred before clamping to prevent wire spiral protrusion at the termination point.
• Ecosystem Positioning: Within a complete atmospheric control ecosystem, this ducting functions as the sealed airflow conduit between the fan, filter, and exhaust point — the infrastructure layer that determines whether the rest of the system performs to specification.

Operator Field Notes

• Measure the run before cutting. The 25-foot length accommodates most single-zone installations, but confirm your fan-to-exhaust distance before shortening. Once cut, the length cannot be restored.
• De-burr cut ends. After cutting, the steel-wire spiral will be exposed at the cut point. Run a finger along the cut edge and use pliers to tuck any protruding wire before sliding the clamp over the end — this prevents the wire from interfering with the clamp seal.
• Clamp torque matters. The included stainless steel clamps should be tightened until the duct material compresses uniformly around the collar — not until the outer PVC layer deforms. Over-tightening can crack the thermoplastic at the clamp band and create a leak point at the termination.
• Avoid sustained sharp bends. The steel-wire spiral maintains the bore under moderate flex, but a sustained 90-degree bend held under tension will eventually fatigue the wire at the bend point. Use a duct elbow fitting for hard 90-degree turns in permanent installations.
• Inspect at commissioning. Before sealing the installation, run the fan at full speed and run a hand along the full duct length to check for airflow at the wall surface. Any detectable airflow through the duct wall indicates a layer breach and the section should be replaced before the installation is closed.
• Label your runs. In multi-zone installations with multiple duct runs, label each duct at both termination points at installation time. Tracing unlabeled ducting in a fully built-out facility is a significant time cost during troubleshooting.
