turbo®II Patented Design

The patented metal designed turbo® II is the only metal precleaner that offers a “Top Down” air flow by drawing dirty air through the protective screen at the top of the unit. turbo® II Precleaners have aerodynamically designed overlapped vanes that force the incoming air to spin and causing 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.

Turbo II Steps

Competitors Design

Competitors typically use “REVERESE AXIAL” designs. This means that the air is drawn in through the base of the unit and then must make a “U” turn which adds restriction and reduces the power of the engine. Additional restriction to the engine will cause the need for more frequent engine filter replacements.

Model Information

turbo® II is currently manufactured in four sizes and covers a CFM range from 100 to 1100 CFM. Additionally turbo® II offers a similar model made out of high strength glass-reinforced polymer that is lighter in weight and easier to install, the turbo® III.
