Donaldson Switch Filter Minder
Being optimistic about engine performance starts with monitoring systems that actually tell the truth. The Donaldson Switch Air Filter Minder gives your setup a way to detect when airflow drops to inefficient levels. With a normally open circuit and combo-style housing, this sensor sits in line with your air filter and triggers when restriction levels exceed what’s acceptable. What’s more, the Donaldson 135578-08425 ’s compact footprint makes it easy to install on most commercial engines that rely on diesel or gasoline air filters with restriction-sensitive metrics.
