Filter testing - ViScan
Air filter tester - ViScan (EN1822)


for particulate air filteres are defined in the European standard EN 1822-1

Tests and procedures for particulate air filters are defined in the European standard EN 1822-1, which references the international standards ISO 29463-2 to 29463-5.

Next to the reference test, a scanning method applicable to all defined filter classes, a much faster oil thread test is allowed to detect leakages.

It can be used for all filters of class H13 and H14 and for those which cannot be scanned (such as V-shaped filters).

Typically the oil thread test is performed manually with a bright light source.

We decided to take it to the next level and implement a fully automated version.

A scanning laser and computerized camera detection system detects and documents all leaks in very short time.

It provides a higher sensitivity than manual testing and automatic report generation makes it ideal for quality control.

The filter measuring set consists of 2 components.

  •   · Filter measuring device FMP 03 and
  •   · universal filter holder FH-143/149 automatic

  · Standards-compliant oil thread test according to ISO 29463-4 (formerly EN1822-4)
  · Fully automated testing
  · Applicable for filters of class H13 and H14 as well as non-scanable filters (V-filters etc.)
  •   · High sensitivity and reproducibility due to camera-based detection system
      · Optional repair-mode with live-view to fix detected leaks
      · Designed for filters up to 610×610 mm in size (other sizes on request)
  •   · Automatic documentation and report generation
