Abstract
An air intake system (20) for a utility vehicle engine (16) is provided. The system comprises an air filter module (21) having a pre-filter (22) upstream of a main filter (24) wherein the pre-filter serves to extract dust from the air stream. The system further comprises a fan module (32) which is dedicated to deliver a scavenging vacuum which sucks said dust through a scavenger vent (28) in the pre-filter. The fan module (34) is secured to the air filter module (21). By providing a dedicated fan for extracting the dust from the system the reliance on the engine exhaust to provide the vacuum is removed. Furthermore, the securing of the fan module to the air filter module reduces the number of components on the vehicle assembly line.
