Face Mask Filter Efficiency and Leak Testing

M2045S, Corn Oil Aerosol Particle Generator Corn Oil Aerosol Generator is designed to provide respirator testing to challenge face mask filters as part of the efficiency certification process.

Face Mask filters generally provide 4/9 or higher efficiency ratings.

The Model 2045-S is a customized atomizer aerosol generator designed to produce a polydisperse distribution of Corn Oil particles between 0.4um and 0.5um at a very high rate for challenging face masks.

The 2045-S can also be set up to generate oleic acid aerosol particles, DOS and DOP (dioctylphthalate) aerosol particles.


  • Minimal double and triple charged particles with the PO210 Ionizer (USA use only)
  • High efficiency, patented atomizer to maintain a small Corn Oil droplet size
  • Consumption of oil is not wasted with fast turn on/off and fast ramp rates
  • Remote operation control permits the generator to be included in filter test systems
  • Very stable output count over long periods of operation
  • Stainless steel enclosure with superb controls
