5.5 Information for filter change
The frequency of the change of filter depends on the degree of pollution of the filter. If the
sealing up of the filter increases (contamination of the filter), the air capacity decreases.
For the control of the filter during the operation, the device is equipped with a
manometer.
Important: Use only authorised, faultless filter!
With filter in new state, approximately 650 Pascal are displayed on the gauge.
(Evaluated at 100 % capacity)
We recommend a filter change at about 1300 Pascal (indicator light filter monitoring is
on)
To determine which filter (main filter, bag filter or pre-filter)at a Manometer value of
about 1300Pascal, is dirty, do the following:
1. Renew the pre and bag filter and switch the device on
2. Pressure gauge value 950 - 1150 Pascal
=> continue to operate the device
3. Pressure gauge value > 1150 Pascal
=> renew the main filter
