Abstract
The invention provides apparatus for separating particles from a fluid flow having a cyclonic separator (,) and a fan (,) for causing the fluid to flow through the cyclonic separator (,), the cyclonic separator (,) having an inlet (,) and an interior wall having a frusto-conical portion (,) tapering away from the inlet (,), wherein the fan (,) is positioned in the inlet (,) to the cyclonic separator (,) such that fluid passing through the fan (,) is accelerated towards the interior wall (,) and thereby given sufficient tangential velocity to cause cyclonic separation of particles from the fluid flow within the cyclonic separator (,).
