Automatic Filter Scanner for Testing of HEPA and ULPA Filters acc. to EN 1822-4

For the first time in India, AAF brings EN1822 Scan tested HEPA & ULPA filters.
A & ULPA filters.

AAF stands committed to build world class products for its respective market. India is a major manufacturing hub for pharmaceutical manufacturing for India as well as USA and other export markets. The cleanroom classification calls for a leak free HEPA filer every time it is validated. A factory test confirming to site test protocol as per EN1822 is a must. EN1822 require full filter auto scan testing in the factory. AAF India has shown its commitment by investing in an auto scan filter test machine to ensure each one of the HEPA/ULPA filter confirms to specific test requirement of EN1822and test it at MPPS.


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. The in-built program calculates the allowable particle on downstream of HEPA. A 3D test report demonstrating the number of particles detected by the scan probe.                   

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 articles 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.

      • Automated test protocols acc. to EN1822-4
        (ISO29463-4, ISO14644-3, IEST-RP-CC034

      • Automatic test report generation as a proof of
        quality in the filter manufacturing – even for
        the low-cost filter scanner version with
        manual testing

      • Flexible “plate in plate” adapter solution for
        different filter dimensions

      • Automatic adjustment of dilution and aerosol
        generation depending on filter class, flow rate

      • Customized data or test protocols possible

      • Convenient control and data acquisition
        software AFS150Win

      • Quality control and assurance in filter

      • For automated testing of high-efficiency air
        filters according to EN 1822-4 (scan-test),
        EN 1822-5 (local penetration and air velocity)
        and EN 1822-3 (fractional efficiency of filter
        media; with additional module AFS 153)
