Atomizer Aerosol Generator ATM 240/L for aerosol generation from liquids, compressed air operated, high mass flow rate, ideal for PSL aerosols acc. ISO 29463

The aerosol generator ATM 240/L is used to generate a highly concentrated aerosol out of a suspension for testing air filters using polystyrene (PSL) particles.

In sensitive areas such as semiconductor and aerospace industry the testing of high efficiency HEPA filters is often not carried out with the commonly used oily aerosol substances (DEHS, PAO, etc.).

Even the smallest amounts of these substances can be stored in the filter and outgas in the application and can lead to product damages. The standard DIN EN 1822-4 describes the filter test with solid particles.
