ABSTRACT:
Air intake systems having filters are useful for removing airborne particles from the air flow. When two filters are used in two separate air systems, one of the filters could become restricted before the other and require more frequent service. The subject air intake arrangement includes a balance tube connected between a first air supply and a second air supply to balance the rate at which the filters become restricted. This arrangement of components will tend to draw more air through the cleaner filter until it is restricted the same degree as the other filter.
