(Additiv) KEMPER Dosing Unit for Pre-coating (Additive)

E. Pre-treatment
For some filter units a one-time pre-treatment of the filter cartridges is necessary!
(Only for filter cartridges without PTFE membrane)
For some cartridges units a one-time pre-treatment of the filter cartridges is necessary!
The powder has to be superimposed onto the new filter material for these filter cartridges
and also to be compressed. You have to hold the bag with the precoating powder to the
extraction opening to extract the powder into the unit. This has to be done during operation
of the machine but before the suction ducting has been connected.
Together with the air stream the powder gets onto the filter surface.
The volume of precoating powder which is necessary can be determined according to the
filter surface of the filter cartridges inside the unit. Per mÇ filter surface you will need 10 g
precoating powder. For a filter cartridge with 12 m 2 surface you will need 120 gr for example.
For the filter surface of your KEMPER extraction and filter unit, please refer to the installation
and operation manual of the unit. Please leave the unit in operation for approximately 2 min.
after the powder has been superimposed.
You can switch off the machine then and connect the suction ducting with the inlet
connection of the filter unit. The unit is ready for operation now.
Attention: An operation of the filter unit without adding precoating powder
can result in damages to the filter cartridges.
