Characteristics of the unit
OFX en(us) Page 19 / 52
BeWa OFX 3796731 en-us 2014-03-31.doc 2014-03-31
Characteristics of the unit
The filtration unit OFX serves as a portable service unit for filling and draining
hydraulic systems. Due to the maximum permitted operating pressure of up
to 45 bar, also supply circuits of hydrostatic transmission drives and work
hydraulics in a closed circuit can be filled and vented.
The handy design and light weight make it ideal for service calls on mobile
machines (e.g. construction, agricultural and forestry machinery, municipal
vehicles).
Existing contamination and air pockets, for example after repairs, are
specifically removed before commissioning in a very short time.
The filtration unit is suitable for:
Flushing and bleeding of hydraulic systems
Filtered oil change during maintenance
For filling preloaded hydraulic systems with filtrated, cleaned fluid.
For filling hydrostatic drives after service or repairs.
