Controlling contamination - The new engines, oils and environmental regulations are great reasons to rethink the filters you use on your equipment

摘要

Good filters and clean shop practices can add many hours, sometimes years of life, to your machines and their components. The best equipment managers have always known this. What's changed in today's environment is that the internal tolerances of components are tighter, the fluid pressures are higher, and with the emergence of new EPA-mandated low-emission engines, the internal chemistry of your power plants is changing. "We don't make anvils anymore," says Frank Scherbing, Caterpillar filter marketing. "We make watches and you have to treat them as such." "Tolerances and clearances have gotten so tight the only way to make the products live longer is through cleaner fluids," says Jim Redpath, Caterpillar contamination control manager.
