Meltblown Cloth Filtration Efficiency Tester for NaCl Oil Aerosol Particle Testing

The Meltblown Cloth Filtration Efficiency Test Equipment is a precision aerosol testing system designed to characterize the particle filtration performance of meltblown nonwoven materials, filter media and other air filtration products under controlled laboratory conditions.

The system uses an aerosol generation module to produce a stable test aerosol and passes the aerosol through the test specimen under a controlled airflow. Upstream and downstream particle concentrations are measured to evaluate the filtration performance of the material.

Both sodium chloride (NaCl) aerosol and oil-based aerosols can be supported, making the system suitable for different filter-media evaluation requirements. Optional aerosol media include DOP, DEHS, paraffin oil and corn oil.

A precision airflow-control system, aerosol generator, photometer and integrated vacuum pump work together to provide a stable testing environment. Temperature and humidity can also be monitored during testing to improve test repeatability.

The equipment features a touchscreen HMI, convenient specimen clamping, automated test operation and data recording, while optional PC software can be used for expanded data management and analysis.

This aerosol filtration efficiency tester is suitable for laboratory evaluation and quality-control testing of filter materials where particle filtration performance needs to be measured under controlled airflow and aerosol conditions.

• Meltblown nonwoven fabric
• Filter media
• Air filtration materials
• Respiratory protection filter materials
• High-efficiency filtration media
• Nonwoven filtration products
• Industrial filter materials
• Laboratory-developed filtration media
• Filter material R&D and quality inspection

It can be used in filter-material manufacturers, R&D laboratories, third-party testing laboratories, universities and industrial quality-control departments.

The equipment generates a controlled aerosol and introduces it into the test airflow. The test specimen is mounted in the dedicated fixture, allowing the aerosol to pass through the specified test area.

The system monitors the aerosol concentration and airflow conditions while measuring the particle concentration associated with the filtration process.

The basic testing process can be summarized as:

Aerosol Generation → Airflow Stabilization → Sample Loading → Aerosol Penetration → Particle Concentration Measurement → Filtration Performance Evaluation

The controlled aerosol generation and precision flow regulation help provide consistent test conditions for comparative evaluation of different filter materials.

• High-Precision Airflow Control: The system provides an airflow range of 0-100 L/min with an accuracy of approximately ±1%, helping maintain stable airflow conditions during filtration testing.
• Dual Aerosol Testing Capability: The system can generate both saline and oil-based aerosols, with optional aerosol media available for different testing applications.
• Controlled Particle Characteristics: The aerosol generation system provides controlled particle-size characteristics, supporting repeatable particle filtration evaluation.
• Integrated Photometer: A dedicated photometer is included for aerosol concentration measurement, forming an integrated measurement chain with the aerosol generator and airflow system.
• Built-In Vacuum Pump: The integrated silent vacuum pump provides stable suction and exhaust operation without requiring a separate external vacuum source in the standard configuration.
• Touchscreen Operation: The touchscreen control interface provides convenient operation and monitoring of test parameters.
• Easy Sample Installation: The dedicated test fixture allows the filtration specimen to be mounted securely and efficiently, reducing setup time between tests.
• Data Recording & Optional PC Connectivity: Test data can be recorded by the system, while optional PC software connectivity can be provided for applications requiring additional data storage, analysis or reporting.
