Abstract

A system to remove debris from a chamber includes a debris chamber, an exhaust pipe, a debris conduit, and a tab. The exhaust pipe may direct a flow of gas into an air outlet, and include an exhaust pipe interior. The debris conduit connects the chamber with at least one of the exhaust pipe interior and the air outlet, and includes a debris conduit end disposed in at least one of the exhaust pipe interior and the air outlet. The tab includes at least three outer edges forming at least two corners, and an adjacent edge. The adjacent edge is adjacent to the debris conduit end.

         16 . The system of  claim 1 , wherein the exhaust pipe includes an exhaust pipe end having a venturi portion with a neck portion, and the debris conduit end is disposed in the neck portion. 
     
     
         17 . The system of  claim 1 , further including a housing defining a compartment; the housing including an air inlet including an air filtration system configured to filter and trap debris in the debris chamber, and the air outlet having an air outlet stack. 
     
     
         18 . The system of  claim 17 , further including an engine disposed in the compartment with an intake manifold and configured to exhaust gases through the exhaust pipe, and wherein the air inlet is fluidly connected to the intake manifold through the air filtration system.
