<p>A fan shroud (10) is provided having an integrated aspirator (28) for use in conjunction with a pre-cleaner (50), the pre-cleaner (50) having an air intake (52), an aspirator port (54), and an air exhaust (56), and wherein a first end (18) of the shroud (10) is adapted for disposal proximal to a cooling module while a second end is adapted for disposal proximal to a fan (22), the fan shroud (10) comprising: an aspirator portal (24) in an upper surface (26) of the shroud (10); an aspirator (28) having an air intake (30) and an air outlet (32), the aspirator (28) being supported inside the shroud (10) proximal to the fan (22) with the air outlet (32) facing the fan (22). A first end of an aspirator hose (62) is connected to the aspirator port of the pre-cleaner (50) and is passing through the aspirator portal (24) and a second end of the aspirator hose (62) is connected to the air intake (30) of the aspirator (28) so that the aspirator hose (62) passes generally through a mid-section of the shroud (10), whereby the vacuum necessary for proper aspiration of the pre-cleaner (50) is accomplished by air movement, induced by the fan (22), between the air intake (52) of the pre-cleaner (50) and the aspirator (28) via the aspirator port (30) and the aspirator hose (62). <IMAGE></p> |
