Filter Media Test System

Test System for multiple parameter testing at filter media, space-saving design by vertical-orientated flow channel. Performance of filter media is essentially defined by parameters such as differential pressure, gravimetric filtration efficiency and dust holding capacity.

This test bench has been designed as universal testing equipment. It combines a simple and robust setup with a manual and therefore cost efficient handling and operation. Because of its vertical test channel setup it is especially suitable for the testing of filter media according to ISO 5011.

Applications

Quality assurance of flat sheet filter media in terms of a final clearance and a receiving inspection

performance testing of filter materials during research and development stage.

- Solid aerosol generator exchangeable by different models of the series

- Control of the Solid Aerosol Generator integrated to the test rig

- Test dust dispersion by using an injector nozzle

- Suitable especially for test dusts ISO 12103-2 A2/A4

Accessories

Differential pressure measurement

Fractional efficiency measurement:
- Aerosol Spectrometer

- Aerosol Dilution System

- Sample Switching, controllable by means of software of aerosol spectrometer or via serial interface

Test Procedures

The flow rate is adjusted by a flow rate unit consisting of an injector pump with a set of critical nozzles;

The intake test air is guided through a dedicated intake section to ensure homogeneous mixing with the test aerosol;

The test filter is mounted in a manually operable filter holder;

The solid aerosol generator can be exchanged with other models of the same series and is fully integrated into the test rig control;

Test dust is dispersed into the airflow using an injector nozzle, making the system particularly suitable for ISO 12103-2 A2/A4 test dusts;

Under defined test conditions, filtration efficiency, differential pressure, and dust holding capacity are measured and recorded.

Maintenance Information

(1) Regularly inspect and calibrate the flow rate unit and differential pressure measurement devices

(2) Keep the aerosol generator and injector nozzles clean to prevent dust blockage

(3) Ensure the compressed air quality meets system requirements

(4) Clean the test channel and filter holders after each test

(5) Store the system in a clean and dry environment during long-term shutdown
