Test System for multiple parameter testing at filter media

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.

Standards

ISO 29463-5

ISO 29463-3

ISO 5011

EN 13274-7

Benefits

Reliable timesaving testing of gravimetric filter efficiency, dust holding capacity, differential pressure and fractional filtration efficiencyholders for test filter and backup filter separately removable, weighable without filter removal

Backup filter for protection of the flow rate unit in case of a filter breakthrough

Integrated Solid Aerosol Generator SAG 410 for feeding rates from approx. 1,5 - 20 g/h

Principle

- Flow rate unit: injector pump with a set of critical nozzles to adjust different flow rates

- Intake test air is directed through a special intake section for homogenous mixing with the test aerosol

- Test filter holding manually operable

- 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
