Vehicle Cabin Air Filter Tester
Application Scenarios
The Air Filter Performance Test System is designed for comprehensive testing of automotive cabin air filters and general particulate filtration media. It is suitable for:
Automotive HVAC system filter manufacturers needing precise testing of particulate filtration efficiency.
R&D laboratories conducting filter performance development, optimization, and validation.
Quality inspection centers performing standardized certification and quality assurance tests.
Environmental control and ventilation product developers requiring accurate measurement of airflow resistance and particle capture performance.
Universities and research institutions engaged in filtration efficiency research, dust loading behavior, and airflow dynamics.
This system supports repeatable and highly accurate tests essential for product development, benchmarking, and compliance verification.
Compliant Standards
The system is fully aligned with internationally recognized standards, ensuring reliable and comparable test results:
DIN 71460-1 – Road vehicles — Air filters for passenger compartments — Part 1: particulate matter filtration tests
ISO/TS 11155-1 – Road vehicles — Air filters for occupants' compartments — Part 1: particulate filtration test
GB/T 14295-2019 – Air filters for general ventilation
GB/T 13554-2020 – High-efficiency particulate air (HEPA) filters
Compliance with these standards ensures that all tests follow uniform procedures for airflow, dust loading, particle sizing, and filtration efficiency evaluation.
