TOPAS CFG 290
The hand-held Condensation Fog Generator
CFG 290 has been designed for use in clean
rooms and for visualisation of air flows according
to ISO 14644-3 Annex B7 and VDI 2083-3.
The fog generation in the CFG 290 is based on the
evaporation of fog fluid at about 300°C and
subsequent condensation. The fluid consists of
polyhydric alcohol and ultrapure water. Because of
the hygroscopic effect of the alcohol droplets a part
of the surrounding humidity is absorbed and
stabilized as fog droplets.
The Condensation Fog Generator generates a
very dense, highly visible fog. This cloud of fog has
a longer life in rooms. Any deposition of fog
droplets on surfaces evaporate after some time
without any residue. According to the principle this
kind of fog is sterile, non-toxic and free of oil and
The Condensation Fog Generator is designed for
mobile use. Power is supplied by a modern LiPo
The device can be equipped with various fog
distributing systems by means of a connection on
the outlet of the aerosol.
