摘要: There is provided cyclonic separating apparatus (100) comprising a chamber (112) for separating dirt and dust from an airflow, an inlet (110) to the chamber (112) and a shroud (200). The shroud (200) comprises a wall (200) having a multiplicity of through-holes (208) forming an outlet from the chamber (112), each through-hole (208) having a width and a height, wherein the through-holes (208) have substantially rectangular cross-sections with width to height ratios in the range of 1.5:1 to 1:1.5. The rectangular cross section of the through-holes (208) maximises the available through-hole (208) area in the shroud (200). This results in a low pressure drop across the shroud (200) and reduces the amount of material required for manufacture. Further, this ratio allows the cross-sectional area of the through-holes (208) to be dimensioned to prevent larger particles of dirt and dust from passing through the through-holes (208) in the shroud (200), whilst still providing the required structural integrity.
