Filter Minder from Donaldson

Wireless monitoring system ensures optimum air filter maintenance on heavy-duty engines

DONALDSON Co. Inc., one of the leading worldwide manufacturers of filtration products and solutions, have introduced their Filter Minder wireless monitoring system for air filters on heavy-duty engines.

Following 18 months of successful field testing, the company announced at Conexpo-Con/Agg 2020 that it is now offering installation and support of this connected technology to optimize fleet maintenance practices in off-road equipment and on-road truck fleets.

Filtration efficiency is lost when filters are changed too soon but unplanned downtime and additional cost can be incurred when filters are changed too late.

To address this issue, Filter Minder wireless sensors and receivers send filter performance data to the Cloud and predictive analytics are used to inform users when their filters are approaching the end of their optimal life.


System components can be installed on equipment in minutes, without hardwiring or an additional cellular device.

‘The Filter Minder wireless monitoring system has been tested in real-world conditions on a wide range of diesel engine air filters,’ said Nate Zambon, director of Filter Minder at Donaldson.

‘Maintenance managers can now make informed air-filtration maintenance decisions about when to conduct maintenance and maximize the life of a filter, instead of changing filters based upon time or distance intervals.’

In a major expansion of Filter Minder’s monitoring capability across equipment platforms, Donaldson are now field-testing their easy-to-install wireless fuel and hydraulic filter restriction monitoring, as well as engine oil condition monitoring.

It will be the first time wireless Internet of Things (IoT) technology has been tested across major air and fluid filtration applications on heavy-duty equipment, with the benefit of optimizing fluid and filtration maintenance, driving down total cost of ownership and increasing equipment uptime.

‘We invite fleet managers to participate in these important tests of fuel, hydraulic and lubrication monitoring,’ said Mr Zambon. ‘With these game-changing applications, we are building Filter Minder into a comprehensive suite of off- and on-road filtration monitoring that integrates into the existing telematics and fleet-management infrastructure.’

Data from the Filter Minder wireless monitoring system is accessible to users via the MyGeotab dashboard. Donaldson recently announced integration with Geotab, a global leader in IOT and connected transportation.
