1. A filter cleaning system for cleaning a tubular filter element defining a central cavity and a central axis, comprising:
- a compressed air supply;
at least one pulse nozzle operatively attached to the compressed air supply and configured to direct the compressed air;
a filter element mounting structure, the at least one pulse nozzle being positioned relative to the filter element mounting structure such that an outlet of the at least one pulse nozzle is radially offset from the central axis when a tubular filter element is mounted to the filter element mounting structure; and
wherein when the tubular filter element is mounted to the filter element mounting structure, the at least one pulse nozzle is arranged in a first semicircle of a cross-section of the tubular filter element, and a target cleaning area of the tubular filter element is in a second, opposite, semicircle of the cross-section of the tubular filter element.
