7.2 MAIN FILTER CLEANING 

 

 

The  Lavina  V20E  uses  jet  pulse  manual  filter  cleaning.  One  cycle  of  filter  cleaning 
takes  10  to  20  seconds,  depending  on  the  vacuum’s  operator.  The  filter  must  be 
cleaned  as  the  vacuum  gauge  goes  to  red  or  if  there’s  low  suction.  If  the  suction 
performance is still not improved after a cleaning cycle is applied, the filter must be 
replaced with new one.  

 

In fig. 7.2 you have the vacuum’s working position (valves 1 and 2 are opened and 3 stays closed). To 
clean the main filter, follow the steps below in the exact order: 

1

st

. Close the valve 2.  This prevents the turbine to suck air through the filter chamber, which 

immediately frees the dust in there, causing it to fall into the longopack plastic bag. This step is very 
important and should not be skipped as it drastically helps in the subsequent filter cleaning. 

 

2

nd

. After discharging the filter chamber, reopen the valve 2 and close the valve 1. This creates a 

vacuum in the filter chamber, indicated by the pressure gauge (fig. 3.1) as it goes to red (-0.2 to -0.24 
bar). 

3

rd

. With the filter chamber under vacuum, open and close the valve 3 - 

3 to 5

 times to clean the 

filter. Allow 

1-2

 seconds between each valve opening to build up vacuum in the chamber again. This 

can also be verified via the pressure gauge. Once complete, return to the normal operating position 
as shown in figure 7.2.
