Primary cartridge filters operation

3. Timer
The filtering cartridges ( 2 ) serve the purpose of filtering
the intake air. The vacuum cleaner is equipped with a fully
automatic electropneumatic device ( 1 ) to alternately clean
the filtering cartridges ( 2 ) which guarantees continuous
service; powered with a 24V rating, is complete with cyclic
timer ( 3 ) to regulate the following times:
T3 = time between one cleaning cycle and the next, set on 0
seconds;
T2 = time between one cleaning operation of the cartridge
( 2 ) and the next, set on 20 seconds;
T1 = opening time of the solenoid valve for backwashed air
exhaust into the cartridge, set at 1 tenths of a second.
The shorter the time, the more energetic the cleaning
action will be.
Factory setting should not be changed if without
consulting Blastrac.
The three solenoid valves of the electropneumatic device
control the cleaning of the relative filter cartridges.

than 20 m/s.
This state is shown by the green indicator of the
primary filter.
When using the vacuum cleaner, check:
■
The state of the max. vacuumed material level indicator
( 6 - Fig. 4) if the level check is installed.
