Filter Minder® Switches

Filter Minder® Single Position Switch Indicator

Air Filter Restriction Monitoring Indicator / Switch

Single Position & Signal Indication / Threaded Mount

How It Works

The Filter Minder® Single Position Switch Indicator is a combination single position indicator and switch. The window turns red when the maximum recommended air filter restriction has been reached and a signal is sent to the filter warning light on the dash or to the engine computer to record as a diagnostics fault. The warning light locks on until the indicator is reset.

The Filter Minder® should be reset whenever the service indicator is checked to determine air filter restriction or when a new air filter is installed. Push the reset button at the end of the service indicator, and the position indicator will return to zero.

Filter Minder® Non-Locking Fuel Switch

How the Fuel Filter Restriction Monitoring Switch Works

The Filter Minder® Non-Locking Fuel Switch continuously monitors the fuel filter and tells when the filter is restricted. Triggers fuel filter warning light via the engine computer or directly to the warning light. For use on diesel suction-side fuel filters.

Filter Minder® Non-Locking Air Switch

Air Filter Restriction Monitoring Switch

Triggers Air Filter Warning Light / Non-Locking

How It Works

The Filter Minder® Non-Locking Air Switch continuously monitors the engine air filter and tells when filter is restricted. Triggers air filter warning light via the engine computer or directly to the warning light. Used for air filter monitoring on diesel, gas, and alternate fuel engines, as well as other applications where low vacuum/pressure monitoring is required.

Filter Minder® Graduated Switch

Air Filter Restriction Monitoring Gauge / Switch

Graduated / Electrical Indication / Threaded Mount

How It Works

A combination graduated indicator and switch, the Filter Minder® Graduated Switch features a position indicator that progressively fills the window as air filter restriction increases, locking at the highest restriction. When it reaches the red zone, or highest recommended restriction, it sends a signal to the filter warning light on the dash or to the engine computer to record as a diagnostics fault. The warning light locks on until the indicator is reset.
