Abstract

A spark arrestor and dust arrestor for same are provided. In one embodiment, the spark arrestor includes a housing having an inlet and an outlet, wherein the outlet is positioned on a dust arrestor mounting side of the housing, and a turn baffle disposed in the housing in a position that creates a tortuous flow path through the housing between the inlet and the outlet. The tortuous flow path includes a low inertia channel formed in the housing having an orientation that directs particles passing through the low inertia channel through an upper portion of the outlet of the housing, and a high inertia channel formed in the housing, wherein a downstream portion of the high inertia channel has an orientation that directs particles passing through the high inertia channel through a lower portion of the outlet of the housing.
