Air cleaner and precleaner (typical example)
(1) Air cleaner
(2) Precleaner
(3) Cup assembly
(4) Valve
(5) Tubes The air inlet system for this machine is designed for applications with extremely heavy dust. A separate air cleaner (1) and precleaner (2) is used to filter the air for each bank of turbochargers.In order to increase the life of the air cleaner elements, a precleaner is used. The precleaner removes most of the larger particles of dust before the particles reach the elements in the air cleaner. As the air enters the upper part of tubes (5), the air must pass through vanes. The vanes cause the air to move in a fast, circular movement. Centrifugal force spins the heavier dust to the outer wall of the tubes. The dust falls down the wall of the tubes into cup assembly (3). When enough dust is accumulated in the cup assembly the dust is expelled through valve (4). The filter elements are located in the air cleaner chamber.
