SPRAY SYSTEM
13.4
If the impurities are ”too dry” or if they contain liquid
particles with excessive viscosity (sluggish), this
drastically reduces the self-cleaning capability and
useful life of the filter unit.
To increase the liquid content in the impurities and/or
reduce the viscosity, small liquid droplets are sprayed
from a nozzle into the air.
The liquid added must be able to dissolve the
impurities separated in the filter. Water is used for
emulsions. The spray nozzle is mounted in the inlet
duct of the filter unit.
The spray nozzle is controlled by a time relay with
adjustable pause and spray period. For instructions
on safety, installation and maintenance, see the
separate instructions for use!
A•mist
filter units can be supplied with a mounted
protective motor contactor.
The A•mist filters unit can be equipped with a
frequency converter with integrated pressure sen-
sor. The pressure sensor measures the negative
pressure before the filte runit and compensates for
clogged filter cassettes and other changes in the
system in order to maintain the air volume stable.
Please contact Absolent / your Absolent represen-
tative for more information.

the carbon
filter cassette can be placed on top of the filter unit
as an additional filter stage. In this case you need to
add a carbon filter hood (see 13.3).
The standard carbon filter cassette contains 21 kg of
adsorbent (active carbon) and has the measurements
595x595x292mm.
