ABSTRACT:
A system for cleaning a particulate trap comprises locating the trap in a chamber and forcing cleaning air through the trap. The air and removed particulates is extracted from the trap towards a filter. The expelled air essentially without the removed particulates from the chamber, the removed particulates being essentially trapped in the filter. The trap is locatable about a longitudinal axis such that air is urged in a longitudinal direction through the trap. The trap is supportable on at least one rotatable roller to affect rotation about the axis. A motor and blower draws air from the chamber and an air pressure differential about the filter causes the particulate to be directed through the filter and excess air is pumped out of the blower by the motor operating the blower.
