How to service the filter
Introduction
There are two kinds of filters:
•
Bag filters
•
Panel filters
This section deals with the service of both filters. The illustrations will help you decide
which kind of filter is used in your DanX unit.
Intervals
The filter must be exchanged when the pressure loss exceeds the recommended end
pressure loss, see table on page 29.
The concentration of dust in the air that passes through the filter decides the intervals.
Use the following methods to decide whether a filter needs to be replaced:
•
A filter guard (if fitted) will give a signal when the filter needs to be replaced
•
A differential pressure gauge will show the pressure loss of the filter; see table
If there is no mechanical equipment to check the pressure loss, replace the filer when
you think it necessary.
Before start
No special tools are needed.
Warning!
Do not forget to disconnect all current to the unit and the unit parts before service.
