Aluminum Non-insulated Duct  ( MODEL: ALU-NOD )

Non-insulated aluminium flexible ducts are specifically produced for low and medium pressure heating, cooling, ventilation, exhaust and air conditioning systems.

Airtight aluminium flexible ducts are produced from multi layer aluminium 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. In case of fire no toxic or poisonous gases are released.

 Aluminum Insulated Duct  ( MODEL: ALU-IND )

(Including Silent / Acoustic Insulated Duct, MODEL: ALU-INDS )

 (Acoustic/Silent insulated duct Punched many small hole, can absorb most of sound from airstream)

Good insulation---heat insulated.
(Absorb noise---can absorb the noise from the shaking when ventilated.)
No corrosive---not corrode the alu. pipe and metal parts.
Durability---not decay, mildew, durability.
Fire---resistance.
Practicality: suitable for the densely-populated area (such as school, supermarket, office, stadium, theater, factory...) high requietment of the enviroment area, such as hospital, laboratory, howff, bus, train, broadcasting studio.

Alum & PVC Combined Non-insulated Duct  ( MODEL: ALPV-NOD )

Aluminum & PVC combined flexible air ducts are specifically produced for discharging welding fumes and dense chemical gases where high mechanical resistance is required.

This product is produced from multi layer aluminium strengthened with high tension steel spring wire, covered with a nonflammable PVC jacket.

Aluminium & PVC combined flexible air ducts are also recommended for heating, cooling and air-conditioning systems.

An important aspect of ALPV-NOD is its non-condensing property. And they are elastic and flexible. They can be easily fitted to circular, oval or rectangular connectors.

Aluminium & PVC combined flexible air ducts are non-flammable.
