Filter Efficiency Test Systems

The requirements for an automated air filter (scanner) test system has to be in accordance to EN1822-3/4/5 to identify the leakage of e.g. flat filters and HEPA/ULPA filters. Grimm has for the efficiency test special Aerosol Spectrometers permitting a fast results of the MPPS (Most Penetrating Particle Size) and other important information on particle number, size and mass. Grimm uses aerosol monitoring instruments for real-time Nano and Micro air quality studies and combines them with different aerosol generators, depending on the standard.



Various System Solutions Available

These counters and sizers can be based on the optical laser scattering method or as size-resolved Scanning Mobility Particle Sizer, which is a combination of a Condensation Particle Counter with a DMA. The test stations can on the one hand be compact and even portable with a sophisticated software package and on the other hand be a complete test stand to monitor the particle sizes and their size distribution in many different size ranges from a few nanometers up to 32 µm.



Customized filter testing systems

Depending on the dimensions of the filters under control, the lot size, the personal resources, and further conditions at the customer site, the best suitable solution for filter testing systems will be recommended.



Portable or stationary aerosol spectrometers

Today, Grimm spectrometers are worldwide in use and starting with two portable aerosol spectrometers for onsite testing up to complete stations in the field for tests and research are operated. Highest performance, quality control and German precision combined with quick customer support are our base for over 20 years of customer satisfaction.
Therefore, Grimm Aerosol is the European leader in the optical particle monitoring field and many scientific articles worldwide show users the use of our aerosol monitors in the filter industry.
