AFS 152/A Automated HEPA/ULPA Filter Scanning System
Automated panel-filter scanning system for local leak detection, local-efficiency measurement, integral-efficiency determination and differential-pressure testing according to ISO 29463 and EN 1822.
Model Overview
| Model | System role | Primary measurements | Standards / application fit |
|---|---|---|---|
| AFS 152/A | Automated HEPA/ULPA panel-filter scanner | Local leak detection, local and integral efficiency and differential pressure | High-throughput automated testing of panel filter elements |
Key Features
Automated scan traverse
A motorised probe scans the filter and frame with controlled speed and position.
Automatic concentration control
Dilution ratio and aerosol concentration can be adjusted according to filter class and flow rate.
High throughput
Automated procedures, acquisition and evaluation support production-oriented testing.
Accurate reproducible results
Controlled scan motion and particle counting reduce variability between operators.
Upgrade path
The automated traverse can be added to suitable existing AFS 152 systems.
Configurable reporting
User-defined reports document filter quality and measured test results.
