Laser Diode Counter Mask Particle Filtration Efficiency Tester (PFE) ISO-29463
Product Overview
The T433S 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 tester requires only suitable power and compressed air (oil-free, water-free) for operation, making it ideal for laboratory and factory environments.
The system employs particle counting methodology to measure counting efficiency using monodisperse aerosol. During testing, filter paper is secured in the fixture, and test air volume corresponds to the required filtration speed. Aerosol generated by the aerosol generator is electrostatically neutralized (PSL), uniformly mixed with filtered test air, and then introduced to the test area to penetrate the filter material.
The equipment also measures filter material resistance during testing and allows for manual flow rate adjustment.

System Components
Aerosol Generator: Utilizes 0.3μm PSL standard particles for high-concentration aerosol experiments. Emits particles ≥0.3μm (comprising over 70% of total output), providing continuous, stable aerosol generation upstream of filter material.
Stainless Steel Fixture: Provides compression and sealing for tested filter materials.
Particle Counter: Monitors upstream and downstream particle concentration to calculate filter material efficiency.
Imported Air Pump: Delivers stable test flow through filter material with minimal vibration and noise.
Differential Pressure Sensor: Measures pressure difference/resistance of tested filter material under specific test flow rates.
Electrical Control & Software: Manages equipment circuit control, operation, software calculations, data processing, upstream concentration stability assessment, operation control, and parameter settings.
