Product Description

The AG-461E Digital Air Permeability Tester is designed for measuring the air permeability performance of filter media and other breathable materials. It supports an air permeability range of 0.2–12826 mm/s, test pressure of 0–4000 Pa, and multiple test areas including 5, 20, 38, 50, and 100 cm².

This model helps manufacturers evaluate filter paper, filter cloth, non-woven fabric, membrane, and other porous material permeability before production or quality approval. With automatic testing, computer control, 11 nozzles, English display, RS232 output, real-time curve display, and statistical analysis functions, it is suitable for laboratory testing and routine filter material quality control.

How the Machine Works

Sample preparation → Filter media, non-woven fabric, industrial filter paper, filter cloth, membrane, or other breathable material is prepared according to the required air permeability testing method.

Test area selection → The operator selects the suitable test head area according to the sample structure, material type, and required testing standard.

Pressure setting → The tester applies the required test pressure within the 0–4000 Pa range to create airflow through the material sample.

Air permeability measurement → The instrument measures airflow performance and calculates the air permeability value with automatic testing and pressure sensing control.

Data display and analysis → The test software displays results, real-time curves, and statistical values such as maximum, minimum, average, and CV for quality control records.
