Aerosol generator max. 8 bar, 250 l/h | ATM 220

Aerosol generators of series ATM 220/226 are especially for cleanroom and filter test applications for years highly appreciated by our customers. Function test at laminar flow boxes (DIN EN 12469), the qualitative test of filters for suspended matter (filter leack test of HEPA and ULPA filters), and acceptance measurements in clean rooms (according to DIN EN ISO 14644 and VDI 2083) are a essential necessity for personal security and product safety. Such measurements and checkouts need a suitable test aerosol. Compartment air or ambient air is not qualified for test aerosol because of their undefined and unsteady particle number concentration and unknown particle size distribution. Therefore VDI-directive 3491 proposes an aerosol generator for producing a test aerosol with defined characteristics, like the ATM 220. By high generated particle numbers at a particle size distribution orientated at the Most Penetration Particle Size (MPPS) of the filter the locating of leaks in the system is possible fast and safe. Using an oily aerosol substance the aerosol generator produces spherical particles mainly in the size range 0,1...0,5µm with a calculable residence time. That does nearly not extra contaminate the filter material.
