Engine Air: Dynamic Air Pre-Cleaners

Equipment operated in dusty environments require more periodic maintenance and experience more down time. The filter element in the air cleaner requires more frequent replacement as the level of dust increases. A plugged filter reduces power, fuel economy, and engine component life.


Racor Composite Dynamic Air Pre-cleaners (EACP series) separate solid dust and debris from the air stream before they reach the main air cleaner. They are installed in place of the rain cap, dust bowl, or aspirated precleaner (exhaust system). In some applications, they can be mounted directly to the air cleaner. Air enters through static vanes at the bottom periphery of the precleaner causing the air to spin and drive a high velocity rotor, which in turn acts as a blower that centrifugally forces dust, dirt, insects, water, and snow through a discharge port. Pre-cleaned air then flows through the outlet to the main air cleaner system and extend the life of the primary air filter from 5 to over 12 times, greatly increasing the air cleaner service interval, reducing
operating cost, and increasing equipment up-time.
