In the field of automotive filters, Topas is THE test expert for reliable testing of all kinds. This applies to the testing of air intake filters, oil mist separators, cabin interior filters and exhaust gas filters (GPF).

With our versatile test systems, you are able to test general air filters, high-efficiency HEPA and ULPA filters and also gas turbine filters in various test routines.

By means of various analyses, we provide you with the parameters that matter to you: differential pressure behaviour, gravimetric separation efficiency, fractional separation efficiency or dust loading capacity of the filter.

For the characterisation of aerosols, we have developed technologies for sampling, sample conditioning, and sample analysis.

With our technologies, you create customized calibration aerosols that you need as a device or aerosol technology manufacturer, as a provider of smart home systems, as a sensor developer or as a calibration laboratory.

We develop devices for the generation of defined aerosols for your studies and experiments, regardless of the source material – powder, liquid, solution, or suspension.

With our technological solutions, you can produce, monitor, and modify coating aerosols according to your specifications.

With modular and smart preparation and analysis technologies, we support you in material characterisation and parameter determinations such as deagglomeration behaviour, particle size distribution, particle concentrations or coarse grain

We support a wide range of specific applications with our reliable technology, ranging from hoover testing to solar cell dusting.
