Fabric Air Permeability Tester

The Fabric Air Permeability Tester is used to determine the resistance of textile materials to the passage of air under a specified pressure differential. During testing, the specimen is firmly clamped by a designated test head with a defined test area, and air is drawn through the fabric at a constant pressure. The air flow rate through the specimen is measured to evaluate its air permeability.

The instrument is designed according to air permeability test standards for textiles, nonwoven materials, and paper products. It provides direct and rapid test results in user-selected units, supporting reliable material evaluation and quality control.

Application

The instrument is suitable for air permeability testing of the following materials and products:

Woven fabrics

Knitted fabrics

Nonwoven textiles

Medical masks and protective textiles

Paper and paper-based materials
