With the ECO III series, Racor engineers have revolutionized the performance of air filtration while simplifying installation and service. The engineered mounting system was designed for flexibility and convenience. The reversible base mounting bracket and included hardware mounts quickly, in any direction to frame rail or firewall. This complete mounting system eliminates the need for custom made, field-engineered and installed brackets for a significant savings of time and money. The ECO III product line is the result of collaborative efforts between Racor engineering and our customers, followed by extensive on-highway, real-world testing and laboratory certifications. Advanced materials and design features allow installation flexibility, superior performance, ease of service, and unmatched customer satisfaction. ECO III is designed for 250 to 400 horsepower engines for over-the-road vehicles, including buses and specialty applications. Because ECO III delivers high efficiency in a small overall package design, the air filtration system can be located closer to turbochargers for increased performance and frees valuable space in the engine compartment.
