Atomizer Aerosol Generators Long-term stable test-aerosol Submicron particle size distribution Adjustable particle production ATM 230 (left) and ATM 220 (right) Aerosol Generator Aerosol generators according to guidline VDI 3491 Individual device solution by use case Applications ATM 210 Aerosol Generator (left) and ATM 226 Aerosol Generator with stainless steel housing (right) The products of the ATM series are used to generate test aerosols with defined properties (VDI 3491). The technological and design solutions of the ATM ensure a high consistency of particle size distribution and particle concentration. The generated aerosol is highly reproducible. Filter testing Aeorosl research, i. e. for inhalation studies, toxicological experiments or for environmental research Calibration of measuring instruments Flow visualisation Cleanroom validation Pump built in Compressed air Quality assurances as well as health and safety aspects require regular testing of filters, the certification of safety cabinets, and testing and validation measurements of clean rooms. 1 10 100 1000 Filter area [m²] tested with 1.000.000P/cf at 0,45m/s Chart of scanable filter area using various ATM aerosol
Open the catalog to page 1Atomizer Aerosol Generator ATM 220 with Diffusion Dryer suitable for generation of Calibration Aerosols Device Designs Depending on the application the individual device models differ in their technical implementation of this operating principle. The ATM 220 is powered by compressed air and is therefore particularly suitable for use in the lab or on the filter test stand. The ATM 226 has an internal compressor, thus being suitable for mobile use for example for validation measurements in clean rooms. The stainless steel casing can be cleaned very easily. The generators of the ATM series...
Open the catalog to page 2Aerosol Generators for High Particle Production Rates ATM 241 Operating Principle For the ATM 241 series, a new nozzle type has been developed (patented). Compressed air is blown through a thin ring slit into the liquid to be nebulised. Shear forces acting between air jet and the liquid at the circumference of this so-called ring slit nozzle form the droplet aerosol. The resulting aerosol stream is fed directly into the aerosol liquid (Laskin-mode). Inertial effects prevent big droplets from leaving the liquid. Venturi effect causes droplets to be taken up by air stream Larger particles are...
