Premium Fabric Material of Nanosox HVAC Duct System >>>
Ten Permeability
Nanosox HVAC duct adopts Unique micro-permeability technology - Small Permeability as 3.6 m3/m2/h (0.2 cfm/ft2) is available to strike a proper balance between anti-condensation and energy-saving, only a small percentage of airflow is permeated from fabric surface for anti-condensation, most air is discharged from precisely calculated orifice towards the targeted area in a very fast pace, which reduces energy wasting at high space.
