Robot HEPA/ULPA Filter Scanning System
Category：Filter Cartridge Filtration Tester
Introduction
Robot HEPA/ULPA Filter Scanning System. The filter scanning test system is used to determine the integral and local particle filtration efficiency and leak detection of 2-dimensional and 3-dimensional filter elements.
Due to the modular setup, different types of test aerosols such as DEHS, paraffin oil and PSL can be used. By default, optical particle counters (OPC) are used for efficiency testing and leak detection, but SMPS measurements or tests with DMA-classified aerosols in combination with condensation particle counters (CPC) can be performed as well. The initial test system is designed for HEPA/ULPA panel filters and cartridges used at moderate volume flow rates. Upon request, this setup is subject to be up-scaled to higher flow rates.
Applications
Product development and quality control of HEPA/ULPA filters
Scanning of panel filters and filter cartridges
3-dimensional scanning of V-bank filters
Standards
ISO 29463-5，ISO 29463-4
Benefits
First commercial solution on automatic 3-dimensional filter scanning
All filter sample dimensions within the robot working range can be defined by the operator
Programming of the robot done by ena-bling fast implementation of new scanning concepts
Principle
The multi-functional test setup allows integral filtration efficiency tests by using a suitable hood assembly in terms of a quick production control check. Furthermore, filters can be scanned on leak detection and local efficiency in moderate time intervals using a polydisperse test aerosol. Working stepwise with a classified aerosol, reliable MPPS curves can be determined during filter development.
