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. Put the safety pin in the highest hole of the hinge
bracket, see figure below. This prevents that the top cover collapse during filter replacement.
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 is 5 – 5.5 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 5 bar is not reached, it is possible that there is a leakage in the pneumatic circuit 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.
