<p>A cyclonic separator and fan combination is provided in which the cyclonic separator (52) comprises a cyclone body (72), an inlet (86) for introducing fluid to the cyclone body (72) in a helical or swirling manner and an outlet comprising a vortex finder (90) arranged substantially centrally of one end of the cyclone body (72). A fan (100) is arranged immediately downstream of the vortex finder (90) and the fan (100) is adapted to accept and discharge fluid having fine particulates entrained therein. This arrangement allows the dirty fan (100) to operate without the need for any additional swirl-inducing means due to the fact that the vortex finder (90) delivers to the fan (100) a flow of fluid which is already rotating.</p> |
