Description of TOPAS ATM 220

Aerosol generators of series ATM 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 (flter leack test of HEPA and ULPA filters), and acceptance measurements in clean rooms (according to DIN EN ISO 14644 and VDI 2083) are an essential necessity for personal security and product safety.

For such measurements the VDI 3491-2 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 oriented 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 … 0,5 µm with a calculable residence time. That does nearly not extra contaminate the filter material.

A further range of application for aerosol generators is calibration of measuring devices and visualization of air flows. That enables measurements of local velocities and flow profiles of the tracer particles by means of optical methods.

The atomizer is the key part of the atomizer aerosol generator ATM 220. It is made of high quality stainless steel and works as a two-stream nozzle, based on the injection principle. The unique feature is that the outlet points towards the wall of the glass vessel which works as the baffle plate. This particle impaction section removes coarse spray droplets and results in a particle size distribution mainly below 1 µm. Depending on the flow rate, the cut point of the impactor varies, but this has quasi no impact on the submicrometer range of the particle size distribution of the aerosol. The air is cleaned by a HEPA-filter before it is introduced to the atomizer.

BENEFITS

  • polydisperse aerosol, mainly submicron (
  • long-term stable generation of aerosols
  • adjustable particle production rate
  • integrated valve for on/off aerosol generation

APPLICATIONS

  • aerosol generation from pure liquids, solutions and suspensions
  • fractional efficency testing of filter media and filter elements
  • generation of long-term stable test and process aerosols
  • calibration and validation of particle measurement techniques
