Donaldson Co. says its full line of filter service indicators provides a cost-effective way to improve the service life of air filters used in on-road and off-road applications. The company offers a variety of devices designed to maximize filter utilization — including models designed for light, medium and heavy vehicles — that are built to resist vibration, breakage, weather, corrosion, dust and dirt.
Filter service indicators — whether electrical, visual, pressure or differential — signal when filters should be changed; these restriction measurement tools are intended to provide a dependable assessment of filter service life that is not possible by visual inspection alone. Although a filter may look “dirty,” in most cases it can go plenty more miles or hours. Attaching a filter service indicator to an air cleaner, in the ducting or remotely helps ensure the longest possible filter life and provide added engine protection.
