ISO-29463 Mask Particle Filtration Efficiency ( PFE ) Test Machine
The Mask Filtration Efficiency Tester is designed for testing filter materials with efficiency grades ranging from 45% to 99.9%, in compliance with international standards. This compact and lightweight testing equipment requires only suitable power and compressed air (no water, no oil) during operation, making it ideal for laboratory and factory environments.
The testing process utilizes particle counting methodology to measure counting efficiency, with recommendations for monodisperse aerosol usage. Pressure drop measurements are conducted at specified filtration rates. Test procedures involve securing filter paper in the fixture, adjusting aerosol generation, electrostatic neutralization (PSL), and uniform mixing with filtered test air before penetration testing of the filter material.

- Aerosol Generator: Produces high-concentration aerosols using 0.3μm PSL standard particles, with ≥0.3μm particles accounting for over 70% of total output. Provides continuous, stable aerosol generation for upstream filter material testing.
- Particle Counter: Monitors upstream and downstream particle concentrations to calculate filter material efficiency.
- Differential Pressure Sensor: Measures pressure difference (resistance) of tested filter material under specified test flow rates.
- Stainless Steel Fixture: Ensures proper compression and sealing of tested filter materials.
- Imported Air Pump: Provides stable test flow through filter material with energy-efficient operation and minimal vibration noise.
- Electrical Control & Software: Manages equipment circuit control, software calculations, data processing, upstream concentration stability assessment, and operational parameters.
