Air permeability tester price is competitive. The whole testing procedure gets completed in below steps. This is often referred to as uncontrolled ventilation. According to these test methods the airflow through a given area of fabric is measured at a constant pressure drop across the fabric.

Fabric air permeability is a nature of air passing through fabric normally under the situation that two sides of fabric exist pressure difference that is to say it is speed that airflow vertically goes through fabric in a prescribed test area pressure drop and time whose unit is mm s or m s. Place the specimen on the specimen fixing plate i. Air permeability can be measured by using distinct test protocols for example astm d 737 and iso 9237. Air tightness also known as air leakage air infiltration or air permeability testing is a quick non invasive procedure put in place to measure the total air lost through leaks in the building fabric.

The volume of air passed per second through per unit area of the fabric is called air permeability of fabric.
