Vacuum cleaner operation

The air speed in the suction tube must not be less
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
(7 - Fig. 4) if the level check is installed.
■ The state of the primary filter (9 - Fig. 4) and the
absolute filter (if installed) (10 - Fig. 4).
■ The state of the low compressor pressure indicator (6 -
Fig. 4).
If one of the indicators is lit, follow the instructions.

Primary cartridge filters operation

Figure 6
1. Electropneumatic device
2. Filter cartridges
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 2 ÷ 3 tenths of a
second. The shorter the time, the more energetic the
cleaning action will be.
Check the arrows on the knobs of the timer (3) for the
exact regulation.
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.

Emergency stopping

Press Stop button (5 - Fig. 4). The vacuum cleaner stops.
WARNING!
The motors and internal components of the vacuum
cleaner will still be electrically powered.
To start the vacuum cleaner, see the starting and stopping
