Description
Digital Air Permeability Tester
The Digital Air Permeability Tester is designed to evaluate the air permeability of fabrics by measuring the passage of air through a test specimen. Air permeability testing is used to determine how easily air passes through textile and other porous materials under specified test conditions.
Globe Tex Industries offers the Air Permeability Tester Series in different configurations for general fabric, filter and non-woven fabric, and high GSM fabric testing. The available models include GTX-AP4, GTX-DA1 and GTX-AP4 (High GSM Fabric Model).
The equipment can be selected according to the fabric type, test area, air-flow range, pressure range and testing application.
Available Models
- GTX-AP4 – Air Permeability Tester for general fabric testing
- GTX-DA1 – Digital Air Permeability Tester for filter fabric and non-woven fabric
- GTX-AP4 (High GSM) – Air Permeability Tester for high GSM fabrics
