Meltblown Nonwoven Particulate Filtration Efficiency Tester

Product Overview

The T433S mask filtration efficiency tester is designed for testing filter material efficiency in the 45% to 99.9% grade range, following international standards. This compact and lightweight tester requires only suitable power and compressed air (no water or oil) during operation, making it ideal for laboratory and factory environments.

The testing process utilizes particle counting methodology with monodisperse aerosol to measure counting efficiency. Filter paper is secured in the fixture, and test air volume corresponds to required filtration speed. Aerosol generated by the aerosol generator is adjusted, electrostatically neutralized (PSL), then uniformly mixed with filtered test air before entering the test area to penetrate the filter material.

The system also measures filter material resistance during testing and allows for manual flow rate adjustment.

System Components

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