Aluminum Foil For Duct

Flexible Aluminum Pipe Material is constructed of a special aluminum foil alloy that prevents corrosion and metal fatigue. Machine fabrication produces a continuous lock seam that permits the duct to be pulled open, compressed, bent, and re-bent without developing leakage. It can be used for concealed venting and eliminates the need for elbows. Various applications include dryer venting, air conditioning, fresh air intakes, heating, and exhausting

Aluminium Flexible Ducting is specifically produced for low and medium pressure heating, cooling, ventilation, exhaust and air conditioning systems.

Aluminum Flexible Air Duct made of aluminium / polyester complex incorporating an elical framework made of harmonic steel wire, insulated by a blanket with high thermoacustic power (thickness 25mm), outer anti-vapour protection by aluminized kraft paper reinforced with glass wire mesh.

The aluminum flexible duct is made of aluminium-polyester casing, reinforced with spirally wound steel wire.
Packaging: 10rm sections, squeezed to 600mm, packed into cardboard boxes.
Flexibility rate (winding diameter): Relative to a specific diameter, i.e. approx. 0.6 x diameter in mm.
Temperature range: - 20°C to + 140°C
Allowable negative pressure: Depending on duct position. For straight sections, you can assume 1/3 of transmitted pressure per diameter.
Fire classification - E.g.-1364.3/A/06/MZ
The product is also available in GREEN series characterized by low emissions of volatile organic compounds.

Features Of Aluminum Foil Duct

Semi-rigid but flexible for easy installation, Fire resistant

1. Aluminum ducting is manufactured with a helically shaped internal crimped aluminum strip.
2. The strip locks together with the aluminum foil in order to form an air tight and leak proof lock system.
3. It ensures excellent strength, making it perfect as a flexible solution for a broad range of venting requirements from low or high pressure heating, as well as for ventilation to air conditioning application.

1. For coupling and sealing pipe joints in ventilation, air condition and refrigeration system, Joining and sealing flexible air duct seams and connections.
2. For coupling and sealing boards, panels, blocks or pipe joints in implementing construction-and-assembling operations.
3. May also be used for other industrial uses requiring a tape with these characteristics and benefits.

Heat and fire resistant, highly flexible and compressible, silver tone color.
Ideal for general purpose exhaust applications including bath fans, air intakes, etc.
Widely used in Bathroom, cafes, offices, a gym, a restaurant, conference rooms, hotels, guesthouses and other indoor ventilation

• heat resistant
• impermeable
• non-flammable
• light
• ageing resistant
• UV-stable

Through self-passivation, aluminum foil also offers corrosion protection. However, in the case of external applications with contact with rain or in the nearby area of seas with salt water, aluminum foil should be varnished or protected in a different way.

Applications Of Aluminum Foil For Duct

Aluminum foil for making flexible duct jacket, air conditioning duct, semi rigid air vent duct, kitchen oil insulation hose etc

Airtight aluminum flexible ducts are produced from multi layer aluminum strengthened with high tension hard steel spring wire. It has high elasticity and flexibility. It can be easily fitted to circular, oval or rectangular connectors.

Application scenarios

Heating, Ventilation, and Air Conditioning ( HVAC systems )

High pressure voltage, medium pressure voltage, low pressure voltage central air conditioning and ventilation system.

• Extraction of solvents,
• Extraction of corrosive gas and fumes
• Low pressure application
• Transfer of hot and cold air, Air conditioning
• Vehicle suction construction
• Engine suction construction
• Exhaust fumes extraction
• Generally used for smoke and dust exhausted.
• Bathroom for air exhausting

The Dundas-Jafine Flexible Aluminum Ducts have various applications such as dryer venting, air conditioning, fresh air intakes, heating, and exhausting.

Semi-Rigid Flexible Aluminum Duct: For multiple uses - dryer, bathroom or kitchen

Aluminium Insulated Flexible Duct

Insulation Aluminum Foil Flexible duct is suitable for ventilation system of high, medium & low pressure central air-conditioning and others. It has high-performance of temperature resistance and fire-proof. The outer structure is consisted of two-layer of PET (high temperature resistance). One layer of them is electroplated with aluminum powder by high voltage static and glass fiber filament is in the middle of two-layer to consist outer structure complexly. Inner tube is made of aluminum-foil paper which is consisted of high quality aluminum alloy and PET (high temperature resistance), it is supported by steel wire of high tension spiral carbon steel.
