Pulse system
The Dust collector is provided with an air pulse cleaning system which increases the life of the filter cartridges
and ensures a constant suction power. The system works by use of pressurized air, built up by a compressor
The air is leaded through a water separator to the pulse system.
The cooled air passes a control valve, which regulates the systems pressure , and then builds up pressure in
the pulse tank.
Normally the pressure in the system lies between 6 and 7 bar. The control valve is activated above 7 bar.
The safety valve mounted on the compressor is activated at approximately 10 bar.
This provision is to ensure that when there is a defect in the Control valve, the pressure in the pulse tank
remains within safe limits.
If the pressure of 7 bar is not reached, it is possible that either the filter of the water separator or the air filter
of the compressor is dirty.
If inspection of the water separator and compressor shows no abnormalities, it is possible that either there is a
leakage in the air tubing, or the control valve is defect. In that case replace the defective parts or have it
checked by Blastrac.
When there is pressure but the pulse system does not function, there might be a problem in the electrical
system which controls the pulsing system. Check the wiring and the PLC-settings.
This unit is at delivery of the dust
collector already programmed with
regard to optimal filter cleaning. If
however doubts arise about settings,
this unit can be checked. We advise to
contact
Blastrac
support in order to
prevent operational problems.
