Flexible Air Ducts

General Properties

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

Airtight ALUAFS is produced from multi-layer aluminium and polyester, strengthened with high tension hard steel spring wire.

ALUAFS has high elasticity and flexibility. It can be easily fitted to circular, oval or rectangular connectors.

The fire resistance of ALUAFS has been tested and certified by various international bodies. In case of fire, no toxic or poisonous gases are released.

The dimensions, tolerances and mechanical resistance of ALUAFS are tested, classified & certified according to EN 13180 standard.

General Properties

SEMIAFS aluminium semi flexible air ducts are flexible, extendable and highly reliable for low and medium pressure air conditioning, ventilation and boiler systems.

  • SEMIAFS is elastic, flexible and stretchable.
  • Oval and circular connectors are easily installed.
  • SEMIAFS is secured using an “INTERLOCK” crimp system. “INTERLOCK” crimp systems minimize separation of the duct when it is stretched or bent.

General Properties

COMBIAFS-HEAVY is produced from multi-layer aluminium & polyester strengthened with high tension steel spring wire, covered with a PVC layer. COMBIAFS-HEAVY is recommended for discharging welding fumes (where high mechanical resistance is required), low and medium pressure heating, cooling and air conditioning systems.

In order to prevent condensation the surface temperature of the duct shall be kept higher than the dew point of the air surrounding it. A PVC layer on the outer surface of COMBIAFS-HEAVY acts as an insulation which makes the duct more impermeable to water and keeps surface temperature higher.

COMBIAFS-HEAVY is elastic and flexible. It can be easily fitted to circular, oval, or rectangular connectors.

The dimensions, tolerances and mechanical resistance of COMBIAFS-HEAVY are tested, classified & certified according to EN 13180 standard.
