Aluminum spiral air duct

Description:

The air duct is mainly connecting air conditioner,The heat or cool water through it to get air conditioner to adjust the air flow or air temperature,to make indoor envrionment more comfortable,The air duct is installed in the end of air-conditioing system,It mainly used in marine or other bulidings such as hospital,airport,school,threater,and so on, Or anywhere need air ventilation.

The air duct is round shape,And be made of stainless steel ,It is more suitable for air conditioning than other material,It could be in high pressure and high velocity air distribution.

The duct mainly be installed on sidewall,Installed cost up to 50% less than traditional rectangular duct work,Vastly reduces air leakage and noise breakout,Reduces energy costs and simplifies air flow measurement.
