HVAC System Round Air Duct

HVAC system round air duct
Advantage:
1.Spiral duct costs less than traditional rectangular duct                                                                        
2.Spiral duct reduces HVAC system noise and cuts air leakage                                                           
3.Spiral duct simplifies air flow measurement                                                                           
 
Application:
a.Air conditioning (including high pressure and high velocity air distribution systems)
b.Ventilation (industrial & tunnel)
c.Warm air heating
d.Fume and dust extraction
e.Pneumatic conveying
f.Exhaust and air intake pipes
g.Humidification
