Hydraulic System


For your convenience, filter elements are available in a variety of media and micron rating efficiencies. Filters can be selected for petroleum- and water-base fluid compatibility. Filter heads are also available in multiple inlet/outlet port sizes and by-pass valve settings.

System performance, design flexibility and product quality are reflected in Fleetguard’s diverse hydraulic filtration product line.
