Most Advanced Particulate Filtration Efficiency Analyzer for Air Filtration

M19 PFE-50 measures filtration efficiency and pressure drop of air-filter media. Classify to ISO 16890 and qualify HEPA/ULPA grades to ISO 29463.

Model: PFE-50 · Industry: Air Filtration

Technology principle

The M19 Particulate Filtration Efficiency Analyzer (PFE-50) measures how effectively air-filter media capture airborne particulates across the full penetrating particle-size range. An automated aerosol control system generates mono- or poly-dispersed challenge particles while synchronised upstream and downstream optical particle counters, plus differential-pressure measurement, resolve fractional and overall efficiency together with resistance. Designed for air-filtration R&D and QA/QC, the PFE-50 lets manufacturers balance capture efficiency against pressure drop and energy use, classifying media to ISO 16890 and qualifying HEPA/ULPA grades to ISO 29463 with reproducible, traceable results.

Applications

  • HEPA / ULPA panel and pleated filters
  • Cabin and automotive HVAC filters
  • Bag and pocket filters
  • Respirator and mask media
  • Vacuum-cleaner and appliance filters
  • Gas-turbine inlet filters

Key capabilities

  • Lightweight, compact and ergonomically engineered, the M19 Particulate Filtration Efficiency Analyzer (PFE-50) pairs a 15" capacitive touchscreen with enhanced pressure- and flow-control hardware, so operators run a full air filtration test sequence with minimal training and markedly shorter cycle times. Available in aluminum or stainless-steel variants, it ships with real-time remote support, USB connectivity and remote-control automation. Domestic manufacturing in India and the USA keeps maintenance cost and downtime low, and a 2-year extended warranty is available.

Frequently asked questions

What does the PFE-50 measure for air filters?

It quantifies particulate capture and resistance: Fractional efficiency across particle sizes Overall and Most-Penetrating-Particle-Size efficiency Differential pressure (pressure drop) at rated flow ISO 16890 / ISO 29463 classification data

How does it outperform manual efficiency testing?

Automated aerosol generation with synchronised upstream/downstream counting and pressure-drop logging removes operator variability, speeds testing and produces standard-ready reports.

How does the aerosol control system improve accuracy?

It: Delivers a stable, characterized challenge concentration Supports mono- and poly-dispersed aerosols (PAO/NaCl/DEHS) Correlates counts with differential pressure for true efficiency Auto-calibrates for reproducibility

What are the advantages of domestic manufacturing?

Local build delivers: Faster service and local support Reduced lead time and spare-parts availability Lower import cost and easy customisation 2-year warranty with on-site support

Can it integrate into air-filter QA workflows?

Yes — secure records, connectivity and PDF/CSV export let efficiency and pressure-drop data feed media development, grading and lot acceptance.

How does it support standards compliance?

Alignment to ASTM F2299 / F2100, ISO 16890 and ISO 29463 plus tamper-proof records keeps air-filter data audit-ready for certification and QA.
