Filtration is critical for most hydraulic systems, but so are the vital additives in your hydraulic oil.
Sometimes, filters can restrain these additives and end up reducing the oil’s effectiveness.
The optimal solution is to minimize the need for filtration in the first place.
The Shell Tellus range, such as the S4 VE, is specifically designed for consistent reliability and longevity while working to minimize varnish and sludge. The Tellus range utilizes Gas to Liquid (GTL) base oils which are produced from natural gas instead of crude oil, the source of many common impurities. Shell GTL base oils also offer lower density and high viscosity index to improve thermal conductivity relative to other Group III base oils.
