Automatic Air Permeability Tester NAAPT-100 – Material Airflow Analysis Equipment

What is Automatic Air Permeability Tester NAAPT-100?

Automatic Air Permeability Tester  NAAPT-100 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.

What Does Automatic Air Permeability Tester NAAPT-100 Measure?

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.

How Does Automatic Air Permeability Tester  NAAPT-100 Work? 

1. Material sample is placed in test chamber

2. Sample is securely clamped to avoid leakage

3. Controlled air pressure is applied

4. Air passes through the material

5. Sensors measure airflow rate

6. System calculates permeability and displays results

Higher airflow = more breathable material
Lower airflow = denser structure
