Ultrasonic Water Fog Generator AFM18 / AFM24 / AFM36

In compliance with the relevant standard ISO 14644 Part 3 Annex B7, periodically cleanroom operators are obliged to supply evidence of their actual airflow prevailing inside cleanrooms. This is achieved by mapping airflow using high purity water fog generators, for example.

The ultrasonic water aerosol/ fog AFM18 / AFM24 / AFM36 (AFM-V = Air Flow Mapper) do make use of non-contaminating purifier water to enable airflows to be visualized in cleanrooms accordingly ISO 14644-3 Annex B7.

  • Visualizing airflow patterns around equipment, tools, hallways, door entries and operators

Ultrapure Fog Machine AFM-LNG-1 / AFM-LNG-2 combined nitrogen demineralized (demi) water fog machine

The AFM-LNG series are high density, portable fog-generating systems for visualizing air flows and turbulences in semiconductor and pharmaceutical facilities. Both available fog systems provide the highest volume, density, purity and lowest pressure output of cleanroom foggers on the market.

Both systems are high-purity fog generators designed for visualizing airflows in cleanrooms. These fog generators produce a high-density fog by mixing steam with liquid nitrogen to produce small (3 µm in diameter), pure water droplets suspended in a nitrogen carrier gas. The resulting fog is highly visible and non-contaminating. The droplets leave no measureable residues when they evaporate in the cleanroom air. The foggers meet the most stringent demands of modern semiconductor and pharmaceutical cleanrooms. As the fog generators are non-contaminating, they are suitable for use in cleanrooms in operation without having to interupt ongoing production or other activities taking place in the cleanroom.
