Structure :
Hose is non-insulated aluminium flexible air ducts arespecifically produced for low and medium pressure heating, cooling, ventilation, exhaust and air conditioning systems. Airtight hose is produced from multi-layer aluminium and polyester, strengthened with high tension hard steel spring wire. Hose has high elasticity and flexibility. It can be easily fitted to circular, oval or rectangular connectors. The fire resistance of hose has been tested and certified by various international bodies. In case of fire, no toxic or poisonous gases are released.

Kitchen Chimney Aluminium Air Ducts
Structure :
- Aluminium semi flexible air ducts are flexible, extendable and highly reliable for low and medium pressure air conditioning, ventilation, boiler systems and chimney liners.
- Hose is elastic, flexible and stretchable.
- Oval and circular connectors are easily installed.
- Hose is made secured using an “INTERLOCK” crimp system. “INTERLOCK” crimp systems minimize separation of the duct when it is stretched or bent.
