1065370010097 - Miller 106537 Air Cleaner Restriction Indicator

Precise Air Filter Monitoring for Industrial Engines

The Miller 106537 Informer Air Restriction Gauge is an essential maintenance component designed for Miller engine-driven welding machines. This precision instrument, often referred to as a "Filter Minder" or restriction indicator, mounts directly to the air cleaner housing or intake piping. Its primary function is to measure the vacuum depression created by the engine's induction system as air is drawn through the filter element.

As an air filter accumulates dust and debris, the restriction to airflow increases. The Informer gauge tracks this restriction, providing a progressive visual reading of the filter's condition. Unlike simple "go/no-go" indicators, this gauge allows maintenance personnel to monitor the gradual loading of the filter, enabling planned maintenance rather than reactive repairs. The device features a "lock-up" mechanism that holds the highest restriction reading even after the engine is shut down, ensuring that the operator can check the filter status during pre-start inspections.

Constructed to withstand the high-vibration and harsh thermal environments typical of industrial welding sites, the Miller 106537 ensures your equipment operates at peak efficiency. A clogged air filter can lead to significant power loss, increased fuel consumption, and excessive black smoke (in diesel engines). Conversely, changing a filter too early is wasteful and increases the risk of introducing contaminants during the service process. This gauge eliminates the guesswork, telling you exactly when the maximum allowable restriction has been reached.

The unit is equipped with a simple push-button reset located on the top or end of the housing. Once the air filter has been serviced or replaced, a quick press of the button returns the indicator to zero, ready for the next service cycle. This is a genuine Miller OEM part, ensuring perfect fitment and calibration for your specific machine's intake requirements.
