Eaton’s compact TWF Twinfil filter systems provide reliability, durability and efficiency to the wind turbine gearbox and its lubrication system.

The TWF Twinfil filter system relies on a combination of a 01.NR 1000 filter element available in different fineness levels and a 2-stage Twinfil filter element. The Twinfil filter element is specifically designed for wind power applications to ensure that the gearbox is never lubricated with unfiltered fluid. It couples the upper coarse filter made of stainless steel wire mesh with a nominal fineness of 25 μm with a fine filter made of 10 μm high-performance glass fiber fleece below.
