AFS 150 Test System

AFS 150 Test System for automated scan testing of HEPA and ULPA filters according to ISO 29463-4 (EN 1822-4) and ISO 29463-5 (EN 1822-5)

The AFS 150 Automated Filter Scanner is designed to meet the requirements of testing air filters according to EN1822-4 = leakage test/filterscan and EN 1822-5 = integral separation efficiency test (analogous ISO 29463-4 and ISO 29463-5) with a high grade of automatisation.

Main components of the test rig for testing high efficiency particulate air filters (HEPA, ULPA) are:|air flow system with flow rate measurement and inlet filter|filter holder cabinet|upstream particle instrumentation (Aerosol Generator ATM 220, particle counter with Aerosol Dilution System DIL 550)|scanning traverse with downstream sampling probe, particle counter (optional air velocity probe)|Electrics, PLC control and Windows software

Depending on dimensions of filters under control, lot size, personell resources, and further conditions at the customer side the appropriate version of filter testing system can be chosen.

Principle

The test filter clamped in the filter holder is passed by a test volume flow and charged with a test aerosol. Leak detection and filtration efficiency measurement is performed automatically. The relevant test data and results are logged.

The system works in overpressure mode. The test air is taken from the ambient air and purified by a HEPA filter after passing through the flow measuring device. Behind the filter to be tested, the scanning traverse is located with the sampling probe of the downstream particle counter.

The data acquisition as well as the control of the entire system is done by the PC placed on a separate movable computer desk.

Throughout the whole testing process (scan) unfiltered air and clean air concentrations are measured continuously, each with a separate particle counter. On the basis of particles counted during the test on the downstream side (clean air side) of the test filter the total filtration efficiency is calculated and possible leaks graphically displayed.
