HYDAC Universal Charging and testing unit FPU help to charge accumulators with nitrogen. They are also useful for checking or changing the existing pre-charge pressure in accumulators.
Therefore, for this purpose, we screw the charging and testing unit onto the gas valve of the hydraulic accumulator. Then, we connect them via a hose to a commercial nitrogen bottle. If the nitrogen pressure is only to be checked or reduced, there is no need to connect the charging hose. Moreover, the unit has a screw-type fitting with a built-in gauge, check valve and a spindle for opening the accumulator gas valve to control the pressure.
What's more, HYDAC piston and diaphragm accumulators can be charged and checked without the need for adapters. Bladder accumulators, however, require an A3 adapter.
