Air Permeability Tester
Application
It is used to quickly measure the permeability of various sheet materials such as coated fabrics, filter paper, filter materials, plastics, etc.
The instrument is used for the air permeability test of special industrial fabrics, general fabrics, knit goods, non-woven fabrics, and industrial filter paper etc. The instrument performance is compliant with the GB/T5453－97 Fabric Permeability determination and other requirements of national standards for test instruments.
With digit display, digital test parameter setting and a highly accurate sensor adopted instead of traditional water column pressure difference test method, and with a microcomputer for test data computation in stead of manual conversion, the instrument is easy in operation and has a high accuracy and efficiency.

How do you test for air permeability?
How a fabric's air permeability is tested:
- The airflow through an area of fabric is measured at a constant pressure drop across the fabric of 10cm head of water.
- The specimen is clamped over the air inlet using rubber gaskets and air is sucked through it by a pump.
