Abstract
A filtration device for filtering air for use with a fuel vapor recovery system, the filtration device including a housing having a cover and a base. The cover defines an outlet and a plurality of inlets allowing air to enter the housing. The housing includes a plurality of internal walls defining a plurality of chambers. The plurality of internal walls define a plurality of inlets configured to direct air entering the device to flow along the inner circumference of a cylinder, thereby generating an air stream having a sufficient flow velocity such that centrifugal force forces contaminants to separate from the air.
