The NAAPT-100 Automatic Air Permeability Tester is a laboratory instrument used to measure how easily air passes through materials such as textiles, paper, and nonwovens under controlled pressure conditions.
It provides quantitative airflow measurement used to evaluate breathability, porosity, and structural uniformity.
The instrument measures:
Airflow rate through material
Pressure difference across sample
Air permeability value under standardized conditions
Output helps determine material performance in industrial and research applications.
Material sample is placed in test chamber
Sample is securely clamped to avoid leakage
Controlled air pressure is applied
Air passes through the material
Sensors measure airflow rate
System calculates permeability and displays results
Higher airflow = more breathable material
Lower airflow = denser structure
NAAPT-100 is used to evaluate how materials behave when exposed to airflow.
