Abstract (en)
A cyclone (42) located upstream of the filter element (56) includes a dip (or riser) pipe (48) connecting them (42, 56). The filter element is above the cyclone and in a variant, the pipe (48) widens like a funnel, above the cyclone. More than one cyclone may be included. A mechanical cleaning system is provided for the filter; this is electrically- or pneumatically operated. The cyclone design is elaborated and claimed separately.
