Donaldson Expands Its Filter Indicator Technology

The company is releasing its Intelligent Filter Indicator which monitors and reports real-time data on the service condition of elements in the hydraulic filter manifolds – allowing operators to change filter elements based on performance versus time.


MINNEAPOLIS, MN – June 17, 2011 – Donaldson Aerospace & Defense, a division of Donaldson Company (NYSE:DCI), a leading, worldwide manufacturer of filtration systems and parts, launches two new filter indicators. The company is releasing their Intelligent Filter Indicator which monitors and reports real-time data on the service condition of elements in the hydraulic filter manifolds – allowing operators to change filter elements based on performance versus time. The second new product being released by Donaldson has combined a differential pressure indicator and bypass valve into one component – saving valuable space and reducing weight.

The Donaldson Intelligent Filter Indicator (IFI) is a filter element health monitoring system invented by Donaldson. This device provides electronic signals based on measurements of differential pressure and temperature to an on-board aircraft data acquisition computer. It is a rugged, fully potted unit compatible with many system fluids. Combined with a Donaldson element specific service algorithm, it allows the operator to monitor the percent of life remaining before filter element replacement. The Donaldson IFI can be sold separately or as part of a complete manifold assembly.

The Electrical Differential Pressure Indicator and Bypass Valve combines two components into one, self-contained cartridge – saving valuable space while reducing weight and cost within a manifold. The indicator is designed to provide an electrical warning signal of impending bypass. The actual bypass opening occurs at a higher differential pressure set point. The indicator will automatically reset after the valve closes. Like the Donaldson IFI, the indicator and bypass combination can be sold separately or as part of a complete manifold system.

Commenting on the company's two new indicators, Sheila Peyraud, World Wide General Manager, Donaldson Aerospace & Defense said, "Once again Donaldson has delivered liquid filtration technologies that demonstrate our advanced engineering expertise. These new indicator technologies demonstrate our ongoing commitment to creating filtration systems and technologies that deliver high standards of quality and performance to meet our customers' ever-changing needs."
