For the toughest environments and the harshest of weather.


The turbo® II MAX doesn’t just perform in the harshest environments— it was built for them. Leveraging our trademark “Top Down” air flow design found in our turbo® II line, the turbo® II MAX is larger and features a hexagonal screen that offers 2 TIMES the debris blocking surface area when compared to the turbo® II. And the turbo® II MAX shines in the worst of the elements— it features an extended, rugged steel “cap” over top of the unit, adding unbeatable protection from heavy rain and snow. 

Keep dirt, debris, dust, and water out of your engine. From its durable metal construction to its high efficiency and low restriction across the entire range, turbo® II MAX is designed for graders, mixers, loaders, haulers, crushers, mining machines, and more. Anywhere a high level of protection is needed and where dust, debris, and the weather conditions are a major issue, the turbo® II MAX is a must.

Signature filtration + protection from the weather

Signature design prevents micro-abrasives, dirt, dust, debris, and water from entering engine. The extended steel “cap” of the turbo II MAX is specifically designed to keep out water in heavy rain and snow conditions.

“Top Down” design, TWICE the efficiency

turbo II MAX leverages our trademark “top down” air flow design, drawing dirty air through the protective screen at the top of the unit and ejecting it out of the bottom, but with a new, larger, hexagonal-patterned screen, you get TWO TIMES the debris-blocking surface area.

700-1100 CFM

turbo® II MAX is available in Model 68, which boasts 700 – 1100 CFM. Model 46 MAX is coming soon!

3 inlet sizes available

turbo® II MAX fits inlet sizes of 6 inches, 7 inches, and 8 inches.

Self-powered and self-cleaning

Focus on work, not on maintenance. turbo® II MAX is self-cleaning and never needs external power or charging.

Prolongs engine life & blocks the weather

The turbo® II MAX precleaner prolongs the life of your engines by significantly reducing engine wear and preventing harsh external elements— including rain and snow— from reaching your engine. It’s the precleaner of choice for equipment operators in the dustiest, dirtiest, outdoor environments.

Promotes maximum engine power

turbo® II MAX promotes clean breathing of your engine, and when ventilation is clean and efficient, the engine performs at maximum potential for a much longer life.

Minimize costly down time

turbo® II Max protects your engine from rain, snow, and particulate as small as one micron, which translates to little or no down time. 

Easy install

turbo® II MAX simply clamps on and requires no complicated installation or extensive tools. From box to installed in just a minute or two.

Lifetime warranty

turbo® II MAX comes with a lifetime warranty on the high-powered, highly efficient ejection spinner.

Turbo 2 Max


The turbo® II MAX leverages our trademark “Top Down” air flow design, drawing in dirty air through the protective metal screen. The turbo® II MAX precleaner has aerodynamically designed, overlapping vanes that force incoming air to spin, causing a highly effective separation of dust and dirt from the air through centrifugal force. Debris is spun down the wall of the main chamber and into a blower chamber, where a high-powered spinner then ejects the impurities through the discharge ports on the base of the turbo® II MAX. The result is the cleanest possible air flowing into your engine. Best of all, the spinner in the base of the turbo® II MAX comes with a lifetime warranty!

Turbo 2 Max



Competitors typically use “REVERSE 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.


turbo® Precleaners are tested to industry SAE J726 and ISO 5011 standards.


turbo® II MAX is currently available in Model 68, which boasts 700 to 1100 CFM. Inlet sizes of 6-inches, 7-inches, and 8-inches available. turbo® II MAX Model 46 is coming soon!
