Abstract
A spin tube assembly for an engine air cleaner is provided. The spin tube assembly includes a housing, a spin tube panel, a plurality of spin tubes and at least one constrictor. The plurality of spin tubes are supported on the spin tube panel in parallel relation to one another. Each spin tube of the plurality of spin tubes includes a helical element causing air entering the spin tube to rotate such that particles within the air are moved by centrifugal action outwardly against a wall of the spin tube. At least one spin tube of the plurality of spin tubes has a constrictor upstream from the helical element thereof. The constrictor causes a localized restriction of air entering the at least one spin tube compared to the spin tubes without constrictors. Methods of use and configuration are also provided.
