The High-Efficiency Filter Test Bench is a specialized system designed to evaluate the filtration efficiency and resistance characteristics of HEPA and ULPA filters under rated airflow conditions. Utilizing DEHS aerosol and high-precision particle counting technology, the bench provides accurate MPPS (Most Penetrating Particle Size) efficiency measurements, resistance testing, and flow–pressure performance analysis. It is engineered according to European high-efficiency filtration principles to ensure reliable and repeatable results.
This test bench is suitable for performance evaluation of high-efficiency air filtration products used in cleanrooms, microelectronics, pharmaceuticals, hospitals, nuclear facilities, aerospace, biolabs, and HVAC systems.
Typical test items include HEPA filters, ULPA filters, mini-pleat filters, panel filters, and high-efficiency fan filter units (FFUs).
It is widely used in filter manufacturers, third-party laboratories, quality inspection institutes, and R&D centers requiring precise MPPS and resistance testing.
The equipment complies with or references the following standards:
EN 1822 Series, including EN1822-5 – High-efficiency air filters
ISO 29463 – High-efficiency filters and filter media
IEST-RP-CC021 – HEPA/ULPA filter testing guidelines
GB/T 6165-2008 – Testing of high-efficiency air filters
Designed based on European principles for MPPS performance testing
High-precision particle counting and DEHS aerosol distribution system
Supports full MPPS efficiency, resistance, and flow curve testing
Stable airflow control with ≤2% adjustment accuracy
Compatible with various filter sizes through interchangeable fixtures
Fully enclosed test channel ensures stability and safety
Automated data output and reporting via integrated printer
Engineered for long-term industrial and laboratory operation
