Mining companies and equipment manufacturers rely on turbo® Precleaners to quickly and efficiently filter out debris, moisture, and dust particles as small as one micron. Unrestricted air flow relates to maximum equipment performance and reduced downtime.


Dirt, dust, pollen, and other debris can wreak havoc for engines in logging trucks and heavy equipment. That’s why the logging industry trusts turbo® Precleaners to promote high airflow for the highest engine power needed to get the job done.

Waste Management

turbo® Precleaners keep the waste industry clean. With a fleet of vehicles and machines working year-round to process waste, power, and up-time is critical. Our product line ensures maximized uptime to your engines, which leads to significant cost and time savings for the life of your machinery.


Dirt, dust, mud, moisture, and clippings can spell disaster for agricultural machinery if not properly filtered away from your engines. For over 40 years, equipment owners, famers, and the agricultural OEMs themselves have relied on turbo® Precleaners to protect their engines.


turbo® Precleaners filter away gravel chips, dirt, dust, water, and airborne particulates from the critical engine parts in the heavy machinery and trucks used for mining and processing aggregates. Improved, clean air intake means maximum engine power, which means maximum profitability, and minimum maintenance downtime and costs.
