In a sheet separating apparatus, for example an automated teller machine (ATM) in which banknotes are removed one by one from a stack (12) of banknotes, includes a vacuum pump (32), and suction unit (10A,B,C,D) connectable alternately between a vacuum enable port (30) of the vacuum pump (32) when a note is picked from the stack (12), and a vacuum release port (42) of the pump (32), when the note is released from the suction unit. Pre-filtered air from the vacuum pump (32) is therefore partially recycled, and dust is substantially excluded from the system.

Sheet separating apparatus for removing sheets one-by-one from at least

An enclosure (12) for electrical equipment (14) includes a fan mounted on an interior surface of the enclosure (12) and adapted to blow air outwardly from the enclosure (12) through a grille (24). The grille (24) includes a plurality of sets (90-96) of short, wide elongated slots, each set (90-96) having its slots disposed perpendicular to a radial direction of the fan hub (44) passing through the slots. The enclosure material between the slot sets (e.g. 90, 92) overlies struts (50) forming part of the support for the hub (44) carrying the fan blades. The construction provides low noise from air blown through the slots, while maintaining robust grille construction.
