Condensation Fog Generator 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.

Visualization of airflows in rooms and airconditioning systems
Particularly suitable for use in clean rooms
Visual leak tests of systems and components
General use as test aerosol or challenge
aerosol, e.g. for filter testing
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 grease.
The Condensation Fog Generator is designed for
mobile use. Power is supplied by a modern LiPo
battery.
The device can be equipped with various fog
distributing systems by means of a connection on
the outlet of the aerosol.

Specifications
Technical Data
Details
The outstanding feature of the CFG is a special
evaporator ensuring the fog generation in a very
short time (few seconds only) after triggering the
fog output.
The heating power is applied only for the actual
time of generation. No stand-by heating is required
due to the short reaction time. This technology
provides a long battery life and a long period of use
in mobile operation.
Due to an innovative new solution (utility model
protection) it is possible to immediately stop the
production of fog, without re-evaporation.
The fog outlet of the injection probe is equipped
with a separator where the condensate droplets
from the injection probe as well as very large
droplets of the fog are deposited. Thus, an
unnecessarily high amount of fog fluid in the test
room is avoided.
In the fog distribution system the CFG 290 can
create sufficient overpressure to ensure uniform
outflow from several openings into the
environment.
