Its innovative design is protected by an utility model and the generated aerosols comply with the requirements regarding particle size (1 ... 2 µm) and concentrations for testing oil mist separators. The design of this generator ensures a very constant particle size distribution and concentration while at the same time providing a high degree of reproducibility.

The device features the possibility to adjust the temperature of the generated aerosols and can be used on a variety of oils. Depending on the type of oil and the pressure of the carrier gas various mass flow rates can be adjusted for a set working temperature.
