AC Infinity Flexible Four-Layer Ducting 25' Long – Durable Aluminum Ventilation Ducting

The AC Infinity Flexible Four-Layer Ducting 25' Long is a durable and versatile ventilation duct designed for grow tents, indoor gardens, hydroponic grow rooms, HVAC systems, exhaust fans, dryers, heating and cooling applications, and air circulation systems.

Built with a rugged four-layer construction, this flexible ducting combines heavy-duty aluminum foil with protective PVC thermoplastic to resist leaks, tears, and cuts. An internal spiral steel-wire structure helps the duct retain its shape while remaining flexible enough to bend around corners and reach difficult installation areas.

Each 25' roll can be shortened to the required length and includes two stainless steel duct clamps sized to match the selected duct diameter, making installation with inline fans, carbon filters, exhaust systems, and ventilation fittings easier.

Available in 4", 6", 8", 10", and 12" diameters, AC Infinity Flexible Four-Layer Ducting provides a practical solution for ventilation systems ranging from compact grow tents to larger grow rooms and HVAC applications.

Durable Four-Layer Construction

The AC Infinity flexible duct features four protective layers for greater durability than basic single-layer ducting.

Its construction combines:

• Dual heavy-duty aluminum foil inner layers
• Dual PVC thermoplastic outer layers
• Internal spiral steel-wire reinforcement

The aluminum interior helps create a flexible airflow pathway, while the thermoplastic exterior protects the inner material from cuts, punctures, tears, and air leakage.

This multi-layer construction makes the ducting well suited for environments where ventilation equipment may be moved, adjusted, or repeatedly handled.

Heavy-Duty Aluminum Interior

The inner portion of the ducting uses heavy-duty aluminum foil designed to withstand airflow associated with ventilation, heating, and cooling applications.

AC Infinity describes the aluminum layer as fire/flame-resistant, adding durability when transferring warmer air through a ventilation system.

The smooth, flexible construction makes the duct suitable for connecting equipment such as:

• Inline duct fans
• Carbon filters
• Exhaust systems
• Intake systems
• HVAC equipment
• Dryer exhausts
• Air circulation systems

Protective PVC Thermoplastic Exterior

The aluminum interior is protected by an outer layer of PVC thermoplastic.

This protective exterior helps shield the ducting from:

• Cuts
• Tears
• Abrasion
• Punctures
• Air leakage
• General installation wear

The added exterior protection is especially useful in grow tents and equipment rooms where ducting may contact tent frames, shelving, walls, ventilation ports, or other equipment.

Flexible Spiral Steel-Wire Structure

An internal spiral steel wire runs through the ducting to support its shape while maintaining flexibility.

This reinforced construction allows the duct to bend and curve through installations where rigid ductwork would be difficult to use.

The flexible design is especially useful when routing ducting:

• Around grow tent frames
• Through ventilation ports
• Around corners
• Above grow equipment
• Between inline fans and carbon filters
• Through attics or utility areas
• Into equipment cabinets
• Through difficult-to-access spaces

The steel-wire structure helps maintain the duct opening while still allowing it to compress, extend, and bend as required.

25' Length for Flexible Installation

Each roll provides 25' (300") of flexible ducting, giving installers plenty of material for both short and extended ventilation runs.

You can cut and shorten the duct to match the installation.

This allows a single roll to be adapted for applications such as:

• Short fan-to-filter connections
• Grow tent exhaust routes
• Intake ventilation
• Longer air-transfer runs
• Multiple custom duct sections

The generous 25' length provides more installation flexibility while reducing the need to join several shorter pieces.

Includes Two Stainless Steel Duct Clamps

Each AC Infinity 25' flexible duct includes two stainless steel duct clamps matched to the selected duct diameter.

These clamps can be used to secure the ducting to compatible:

• Inline fans
• Carbon filters
• Flanges
• Duct adapters
• Exhaust ports
• Ventilation fittings

A properly secured duct connection helps keep the ventilation system stable and can reduce unwanted air leakage around connection points.

Ideal for Grow Tent Ventilation

The AC Infinity Four-Layer Flexible Ducting is especially well suited for grow tent ventilation systems.

You can use it to connect an inline fan to a carbon filter and route warm or stale air away from the cultivation area.

Common grow-room applications include:

• Exhaust ventilation
• Intake ventilation
• Carbon-filter connections
• Inline fan installations
• Heat removal
• Air circulation
• Grow-room air transfer

Its black exterior also provides a clean appearance that integrates well with many indoor growing and ventilation systems.

Connect Inline Fans & Carbon Filters

Flexible ducting is an essential component in many inline fan and carbon-filter systems.

A typical ventilation configuration may include:

Carbon Filter → Inline Fan → Flexible Ducting → Exhaust Point

Depending on the installation, you can adjust the fan and carbon filter positions while the flexible ducting routes airflow to or from the desired location.

AC Infinity's wide range of duct diameters makes it easy to match the ducting with appropriately sized fans, filters, flanges, and ventilation accessories.

Useful for HVAC & Home Ventilation

Although it's especially popular for grow-room ventilation, this flexible ducting also suits a range of HVAC and household ventilation applications.

Suitable applications can include:

• Heating and cooling air transfer
• Dryer ventilation
• Bathroom ventilation
• Attic ventilation
• Exhaust systems
• Air circulation projects
• HVAC duct fan systems

Its flexible structure simplifies installation in locations where rigid metal ducting may be difficult to route.

AV Equipment & Electronics Cooling

AC Infinity also identifies this ducting for use in AV and electronics cooling applications.

Flexible ducting can help route warm air away from:

• AV equipment rooms
• Equipment closets
• Server or electronics cabinets
• AV racks
• Enclosed media equipment

Paired with an appropriately sized ventilation fan, the ducting provides a convenient pathway to move heated air away from enclosed equipment areas.

Available in Multiple Duct Sizes

The 25' AC Infinity Four-Layer Flexible Ducting series is available in several diameters to suit different ventilation systems:

• 4" x 25' – Model AI-DTA4
• 6" x 25' – Model AI-DTA6
• 8" x 25' – Model AI-DTA8
• 10" x 25' – Model AI-DTA10
• 12" x 25' – Model AI-DTA12

Choose the duct diameter that matches your inline fan, carbon filter, exhaust port, or ventilation fitting.

Matching the correct duct size helps create a cleaner installation and avoids unnecessary reducers or adapters.

Easy to Cut & Customize

You can shorten the flexible duct to the exact length you need for your installation.

This makes it useful for custom ventilation layouts where standard fixed-length ductwork may not fit properly.

Before cutting, measure the required duct length and leave enough material to securely attach the duct to the fan, filter, or fitting.

Suitable for Compact & Large Ventilation Systems

Available from 4" through 12", this series accommodates a wide range of airflow systems.

Smaller sizes can work well for:

• Compact grow tents
• Small inline fans
• Equipment cooling
• Local exhaust systems

Larger sizes can be used with:

• High-airflow inline fans
• Large grow rooms
• Commercial-style ventilation
• Larger HVAC installations
• High-capacity exhaust systems

Always select ducting based on the diameter and airflow requirements of the connected equipment.
