The Design

turbo® III Precleaner is made out of 33% glass-reinforced polymer (nylon 6), and is designed with the same “TOP DOWN” airflow as the turbo® II. The “Top Down” design draws dirty air through the protective screen at the top of the unit. The patented “stacked vane” forces the incoming air to spin and cause separation of dust and dirt from the air by centrifugal force. The dust and debris then spins down the wall of the main chamber and into the blower chamber where the high velocity spinner forces the dirt to the discharge ports at the base of the unit. As the velocity of the primary air stream increases, it ejects out additional dirt and debris providing the cleanest possible air to the filter element. This design offers exceptional balance between added restriction and efficiency. The new patented “stacked vane” configuration has improved the precleaner efficiency by preventing the blow-through effect common in other polymer units.

Turbo III The Design

Model Information

turbo® III is currently manufactured in four sizes and covers a CFM range from 15 to 1100 CFM.

Additionally, turbo® III is also available as an “inline” model (Flex-N-Line™) for mounting the Precleaner under the hood and allowing the engine to still draw in fresh, clean air in high dust environments.
