Use cases & applications
Dusty Construction Sites
In environments with high airborne debris, the 25 µm impregnated paper media traps fine particles before they enter the engine oil. This reduces wear on bearings and cylinder walls, extending engine life between overhauls.
Continuous-Duty Generators
For generators running 24/7, consistent oil filtration is critical. This filter maintains oil cleanliness over long intervals, helping to prevent sludge buildup and ensuring reliable power output.
Fleet Maintenance Consolidation
Workshop managers can stock one filter for multiple brands including Ammann, Argo, and Renault Trucks, simplifying inventory. This reduces the risk of stocking the wrong part and speeds up service for mixed fleets.
Off-Road Agricultural Equipment
Tractors and harvesters operating in fields face constant dust and moisture. The impregnated paper media resists water ingress while capturing 25 µm particles, protecting engines during long harvesting seasons.
