1. A nozzle for a filter cleaning system, the nozzle comprising:
i) a stub portion having an inlet opening and an outlet opening; and,
ii) a splitter portion positioned downstream of the stub portion along a longitudinal axis of the nozzle; wherein the splitter portion has deflector surfaces arranged to direct airflow exiting the stub portion outlet in three or more separate airstreams, each of which airstreams are directed inclined axially outwardly from the axial direction of the airflow exiting the stub portion outlet opening;
wherein the deflector surfaces directing each airstream are substantially planar, inclined surfaces and at least two of the deflector surfaces for each airstream define an airstream channel; wherein each airstream channel is of substantially the same shape and configuration as the other separate airstream channels of the nozzle; and wherein the stub portion and the splitter portion are arranged such that substantially all the airflow exiting the stub portion is deflected by the splitter portion, into one of the three or more separate airstreams.
