1, Aluminum Bare Flexible Duct  

  

Aluminum bare flexible duct (Aluminum non-insulated flexible duct) is specifically produced for low and medium pressure heating, cooling, ventilation, exhaust and air conditioning systems. Aluminum non-insulated flexible duct (ABD series) is produced from multi layer aluminum strengthened with high tension hard steel spring wire. It has high elasticity and flexibility.

2, Aluminum Insulated Flexible Duct    

 

Aluminum Insulated Flexible Duct is made of aluminum/polyester lining with well balanced steel spiral internal duct+(16-32)kg/m3-25mm glass wool+ aluminum/polyester external duct.
It is suitable for the densely-populated area with high requirement of the environment area, such as school, hospital, laboratory, supermarket, office, stadium, theater etc.
