Proper maintenance of pollution control equipment ensures optimal performance and the cleanest air possible.

Some fleets that worked with Project Green Fleet in the past received a closed crankcase filtration system (CCFS). This piece of equipment requires a filter change approximately once or twice a year, or about as often as you change the oil in your vehicle.

Project Green Fleet provided two replacement filters per school bus free of charge. For more information on filter replacement, please click below on the vendor that provided your equipment
