Hydraulic lines are used in industry for many purposes. Apart from automobile use, oil
filters are also used to lubricate large bearings. All of this oil needs to be filtered and the level of filtration is much more stringent than that of standard automobile filtration. In these applications many times a resin impregnated glass fiber filtration media down to even lum is used, whereas in automobile filtration it is always cellulose which has a micron rating of 50um or more. Industrial applications do not change their oil frequently as it adds to the cost changing tens of thousands of gallons of oil. This is why much higher quality
filters of BERTACCHI E FILIPPI IMPIANTI are usually used.
Hydraulic filters are used for handling petroleum-based oils, emulsions, synthetic
hydraulic fluids and lubrication oils. A high percentage of all hydraulic
system failures are caused by contaminants in the fluid. Applications include mobile hydraulic including earth moving equipment, forest industry equipment, industrial equipments and airplane towing trucks. Marine applications include lube oil hydraulic filters for ship engines, hydraulic winches, and ships' cranes. General industrial applications include die casting machines, power packs, test rigs, saw mills, mining machines, and lubrication filtration in the steel and paper industries.
