Automatic Feeding HEPA Filters Scanning Test System
The Automatic Feeding HEPA Filters Scanning Test System is a fully automated equipment designed for high-efficiency air filters (HEPA and ULPA) used in cleanrooms, semiconductor plants, pharmaceutical manufacturing, medical facilities, and precision electronics industries.
It is used to perform:
Average efficiency, local efficiency, and resistance testing of HEPA filters under rated air volume conditions.
Leakage detection through a point-by-point scanning method, precisely identifying leakage positions on filter media and frames.
Automatic feeding, testing, and sorting for large-scale production lines to achieve continuous and high-efficiency testing.
The system ensures reliable detection of micro-leakages and overall performance evaluation of filters ranging from E10 to U15 grades, in compliance with global standards.
Compliant Standards
This system is designed and manufactured according to the following international and national standards:
EN 1822-4 — High Efficiency Air Filters (EPA, HEPA, ULPA) — Part 4: Determining leakage of filter elements (scan method).
GB/T 6165 — High efficiency air filter performance test method: Efficiency and resistance.
ISO 29463 — High-efficiency filters and filter media for removing particles in air (international equivalent to EN 1822).
These standards ensure traceable, repeatable, and globally recognized test results, suitable for filter certification and quality assurance.
