Abstract
Apparatus (10, 110, 210, 310) for separating particles from a fluid flow comprises an upstream cyclonic separator (12, 112, 212, 312) and a plurality of downstream cyclonic separators (26, 126, 226, 326) arranged in parallel with one another. Each of the downstream cyclonic separators (26, 126, 226, 326) projects, at least in part, into the interior of the upstream cyclonic separator (12, 112, 212, 312). This arrangement provides a compact and economic apparatus which is particularly suitable for applications such as vacuum cleaners.
