Air intake system for power machines

An air intake system for a power machine, comprising:

• an air inlet coupled to an exterior panel of the power machine;
• a filter assembly including a filter enclosure and a filter element;
• a first air conduit coupled, and extending downwardly, between the air inlet and a top of an enclosed frame compartment of a frame of the power machine, the enclosed frame compartment supported on the frame and isolated from an engine compartment that is defined by the frame rearward of the enclosed frame compartment;
• and
• a second air conduit coupled, and extending rearwardly, between a side of the enclosed frame compartment and the filter enclosure;
• wherein the air intake system guides air flow to the filter assembly to travel along an air intake path that includes, in order, the air inlet, the first air conduit, the enclosed frame compartment, and the second air conduit, prior to entering the filter enclosure, and wherein the first air conduit extends in a substantially vertical direction relative to the power machine and the second air conduit extends in a substantially horizontal direction relative to the power machine.

A method of providing air to an engine of a power machine, the method comprising:

• drawing air into an air inlet arranged on an exterior of the power machine;
• flowing the air from the air inlet downwardly through a first air conduit coupled between the air inlet and a hollow frame member of a frame of the power machine;
• flowing the air from the first air conduit downwardly through an enclosed frame compartment of the hollow frame member;
• and
• flowing the air from the enclosed frame compartment through a second air conduit coupled between the enclosed frame compartment and an engine compartment that supports the engine at a rear end of the power machine, in alignment with a filter assembly of the engine, such that the air flows toward the rear end of the power machine and away from an operator station of the power machine, flowing the air from the air inlet to the hollow frame member along a substantially vertical flow path, relative to a side elevation perspective;
• and
• flowing the air from the hollow frame member toward the engine along a substantially horizontal flow path, relative to the side elevation perspective.
