1. A separator for separating entrained particles from a fluid flow, the separator comprising:

  • (a) a cyclone chamber having an outer wall and a cyclonic flow region;

    (b) a fluid inlet for introducing a cyclonic fluid flow to the cyclonic flow region;

    (c) a fluid outlet for removing the fluid flow from the cyclone chamber;

    (d) a particle separation member positioned in the cyclone chamber beneath at least a portion of the cyclonic flow region, the particle separation member having an upper surface and plurality of apertures; and

    , (e) a particle receiving chamber disposed beneath the particle separation member for receiving particles passing into the particle receiving chamber through the apertures wherein the number of apertures in the particle separation member is calculated by the formula;
