Heavy Duty Engine Intake Air Precleaners


Improving productivity and extending equipment life are key operational issues which have important and direct effect on profitability. One key way to cost-effectively achieve these goals is to use turbo® Precleaners by Maradyne to protect valuable equipment and their engines. In demanding environments where dust, dirt and debris are a given, installing turbo® Precleaners on a wide range of equipment is a critical strategy to reduce downtime, increase efficiency and lower maintenance costs. No matter what industry or application, if it’s a dirty job, turbo® Precleaners can handle it. For over 40 years, American-made turbo® Precleaners have set the standard for precleaner technology in industries around the world, including construction, mining, logging, waste, agriculture and aggregates – any application where dust and debris can cause problems for engines. In fact, turbo® has become such a widely-used and accepted product that the brand name is often used as a generic term when referring to precleaners, as in, “we need a turbo® here to protect our equipment."

What sets turbo® Precleaners apart from other precleaner brands is a straight-through airflow pathway which creates less air intake restriction to optimize engine power. Engineered paddles create centrifugal force which ejects up to 85 percent of contaminants through discharge ports. This unique design effectively removes airborne debris such as dust, dirt and moisture, including particles as small as one to two microns, ultimately allowing only filtered air into the engine for maximum performance.Reducing equipment downtime and achieving maximum productivity are major benefits of turbo® Precleaners technology. With a precleaner providing efficient preseparation, the need to take equipment out of service for air filter maintenance is greatly reduced.

turbo® Precleaners users in industries from cement manufacturing to recycling have reported dramatic service life improvements, with filter change intervals going from days to weeks or even months. Maintenance is not only figured in downtime but also in material cost. By extending the life of air filters, turbo® Precleaners reduce the expense of replacement filter purchases. A recent filtration industry trend is towards air filters designed with media that cannot be cleaned but instead require complete replacement.turbo® Precleaners provides four different precleaner models designed for a wide range of equipment operating in light to severe-duty applications. From compact equipment to sweepers, crushers and surface drilling rigs, there are turbo® Precleaners available to protect a variety of machines and their engines with 15 to 1500 cfm airflow range. All high-quality turbo® Precleaners are independently tested to ISO 5011 standards, and some models are available with extended raincap, low-profile bull-nose or under-the-hood options.
