The Atomizer Aerosol Generator ATM 230 produces droplet aerosols with known properties according to the guideline VDI 3491-2.
Standards
VDI 4258-1
VDI 3491-2
ISO 21083-1
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)
Accessories
- aerosol substance DEHS
- further aerosol substances e.g. PAO (Emery 3004) on request
- upgrade kit for operation with salt solutions
