HYDAC offers youcomponents for servicinglubricants for heavy dutytransmission systems.In addition to the singleand change-over filterhousings, the filter rangealso includes thenecessary filter elementswith low pressure drop,ensuring long-lastingand fault-free operation.

The quality of HYDACcomponents guaranteesthe correct functionand increases the lifeexpectancy of your systemsand machines.The filter range includescomplete filter systemswith or without automaticback-flushing. They extendthe service life, improvethe quality of the fluidto be filtered and reduceproduction costs.In mining and tunnelling, hydraulic props

and shields support the wallsof the cavity against the rock pressure.This electrohydraulic construction protects menand machines from underground risks.HYDAC’s filtration products protectthese high-quality products from breakdown,ensuring fault-free and safe operation.We provide you with filter designs tailoredspecifically to the demands of your operation,e.g. self-advancing support,central HFA recovery, etc.
