How many different permeability of the DurkeeSox fabric duct system to choose? Why have that much different permeability materials? What will happen when using wrong permeability fabric material?
There are 10 different standard permeability fabric materials. Also, we can customize the permeability for some special projects. The deviation of the fabric permeability is less than 5% which is very difficult.
The DurkessSox fabric duct system with reasonable and accurate permeability is the guarantee of the effect of air conditioning. We have to use different permeability of fabric duct for different height or air flow quantity or air flow pressure or covering area, with anti-condensation and energy saving purposes to ensure the effect of air condition.
For example, a chiller with low air flow pressure, if we use the fabric duct with small permeability could result the condensation water because less airflow permeate through the fabric duct. A chiller with high air flow pressure, if we use the fabric duct with large permeability could result the energy lost greatly in high place, air pressure lost, fabric duct shaking or not bulge, also will damage the chiller because overload working.
