7.2. Cleaning the filter cartridges
Handycart without automatic cleaning mechanism:
The filter cartridges are reusable filters and can be cleaned. The cleaning of the filter cartridges is
carried out manually.
The degree of pollution of the filter cartridges is electronically monitored. When the maximal admissible
differential pressure value is reached, the device triggers “filter alarm” (see chapter “description of the
control elements”). Now a cleaning is necessary. If despite of the cleaning of the filter cartridge the
alarm value is not undercut anymore, the filter cartridge must be replaced. (see chapter: “Replacing the
filter cartridges”).
●
Close all front service doors in case they are open.
In case the service doors are open, dust can escape during the cleaning.
●
Open the toggle levers and remove the turbine housing.
●
Use a compressed air pistol for the cleaning. These must be connected to the external
compressed air supply of the operator.
The compressed air must be dry and oil-free. The operating pressure must be
between 1,5 and 2,0 bars.
●
Hold the compressed air pistol into the interior of the filter cartridge. Blow steadily with the
compressed air pistol into the crinkles of the filter cartridge. Clean it for at least 5 minutes.
●
Put the turbine housing back on the filter housing. Close the toggle levers.
Handycart with automatic cleaning mechanism:
The filter cartridges are reusable filters and can be cleaned. The cleaning of the filter cartridges is
automatically carried out, according to a preset time interval.
The filter unit remains in operation during the automatic cleaning. The compressed air blast is produced
in opposite direction to the intake. The cleaned dust falls downwards in the dust collecting tank.
When the maximal admissible differential pressure value is reached, the device triggers an alarm (see
chapter “description of the control elements”). If despite of the automatic cleaning of the filter cartridge
the alarm value is not undercut anymore, the filter cartridge must be replaced. (see chapter: “Replacing
the filter cartridges”).
