Why Is Durkeesox Air Duct the Preferred Choice for Food Factory Air Distribution?
Solutions for Air Supply Using Cloth Air Ducts in Badminton Halls
Three Steps to Identify the Authenticity of Durkeesox Ducts
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.
