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 hoses and connectors for leakage and check electrical
wiring for damages.
Advised is to take contact with Blastrac Support in order to prevent operational problems.
