Filter Minder® Visual / Mechanical Indicators & Gauges

Filter Minder® Air Pressure Gauge

How It Works

The graduated pressure gauge monitors the crankcase oil recovery filter and other low pressure applications. The position indicator progressively fills the window as filter restriction increases, locking at the highest restriction. The filter should be changed when the position indicator reaches the red zone.
