Filter replacement
By mounting new filter cartridges pay attention that their gasket at the upper side lies
firm at the sheet steel of the filter chamber. A tilt of the filter cartridge result in leakage
and they suction contaminants in the clean part and consequently blow they backwards in
the outer air.
Pulse system
The Dust collector is provided with a air pulse cleaning system which increases the life of
the filter cartridges.
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 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.
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.
Advised is to take contact with Blastrac Support in order to prevent operational problems.
