Vehicle Cabin Air Filter Tester

The Vehicle Cabin Air Filter Tester is a precision instrument designed to evaluate the filtration performance of passenger compartment air filters used in automobiles. It measures particulate matter filtration efficiency, pressure drop, and dust holding capacity, providing accurate and repeatable data essential for product development, quality control, and regulatory compliance. The tester combines advanced aerosol generation, dust dispersion, and particle counting systems to simulate real-world operating conditions and capture reliable performance indicators.

Application

This tester is widely used in automotive R&D centers, filter manufacturing facilities, quality control laboratories, and third-party testing institutions. It is suitable for testing cabin air filters of passenger vehicles, commercial vehicles, buses, and specialized transport equipment. The instrument evaluates filter performance under controlled airflow, particle loading, and environmental conditions, providing insights into efficiency, airflow resistance, and dust holding capacity. It supports product validation, development of high-efficiency filters, compliance verification with international standards, and routine quality assurance in production lines.

Standards

The Vehicle Cabin Air Filter Tester is designed in accordance with the following standards:
