The gearbox application is complex and needs to maintain oil cleanliness to minimize costly rebuilds and avoiding system downtime. Gearbox applications generally have high viscosity oils which can be difficult to filter. Draining and re-filling gearboxes with new oil does not always provide optimum cleanliness, there is typically residual particulate that stays in the system after draining.
Viscosity is the most important factor followed by the correct filter housing and filter. Oil temperature greatly impacts the viscosity levels. Managing these elements effectively will allow the maintenance team to reach their desired cleanliness targets quickly.
Offline filtration is a very cost effective way to drive savings. A portable filter cart can be deployed across many gearboxes providing a clear solution to maintaining system cleanliness. There are many filter cart options and they should be considered carefully prior to the requisition of a new offline filter cart system.
