ATM 230

Atomizer Aerosol Generator ATM 230 for aerosol generation from liquids, compressed air operated, high mass flow rate

The Atomizer Aerosol Generator ATM 230 produces droplet aerosols with known properties according to the guideline VDI 3491-2.

The ATM 230 is designed as a serial instrument with an external compressed air supply. The liquid reservoir is arranged within the housing.

The ATM 230 provides a high aerosol output. Its design and technical solution warrants highly constant particle size distributions as well as particle concentration with high reproducibility.

The ATM 230 is able to aerosolise various liquids, for example PAO (Emery 3004), DEHS, salt solutions, PSL-standards suspensions.

Benefits

  • polydisperse aerosol, mainly below 1 μm (DEHS)
  • excellent stability in generation of particle size distribution and particle concentration
  • suitable to produce PSL aerosols
  • by variation of the nozzle pressure, the particle production rate can be adjusted in a wide range

Applications

  • testing of HEPA and ULPA filters and filter media
  • acceptance tests of large cleanroom facilities
  • visualisation of air flows (tracer particles)

The atomizer is the core component of the ATM 230. It is made of high quality stainless steel and works as a two-stream nozzle, based on the injection principle. The atomizer is equiped with a impaction plate that serves for removal of coarse droplets.
