Two-stage Air Cleaners
Why an Air Intake System?
Air is a critical component of combustion for a diesel engine. If the air reaching the engine is not clean, the engine will lose efficiency and have engine wear. The engine will run longer and more efficiently with a proper air intake system that is designed to keep the engine intake air as clean as possible by removing par- ticulate matter or debris that would cause engine wear and ultimately failure.
Air entering a two-stage air cleaner is first pre-cleaned before reaching the main element. The air may either be sent through pre-cleaner tubes or cleaned by centrifugal flow around the filter. Depending on the type of pre-cleaner, the pre-cleaner removes between 75-98% of the contaminate from the air before the air reaches the main element. Two stage air cleaners are recommended for use in medium- and heavy dust environments, such as in agricultural, construction, and mining applications.

Main Element Is the filter element in the air cleaner that removes around 99,9% + of the air's dust. The air flows through the main element first. Safety Element Is an optional element that protects the engine during servicing of the main element and in case of a leak in the main element.

Safety Element
Air Cleaners in which the air goes through the inlet and directly to the main element are considered one- stage air cleaners. One-stage air cleaners are typically used where there is less contaminate in the environment, such as in on-road applications.
