HYDAC Standard Accumulator Charging Kit (FPU-1-250 F 2.5 G2 A3/H)

The HYDAC charging and testing unit FPU is used to charge accumulators with nitrogen or to check or to change the existing pre-charge pressure in accumulators. For this purpose the charging and testing unit is screwed onto the gas valve of the hydraulic accumulator and connected via a flexible charging hose to a commercial nitrogen bottle. If the nitrogen pressure is only to be checked or reduced, the charging hose does not need to be connected. The unit has a screw-type fitting with a built-in pressure gauge, check valve and a spindle for opening the accumulator gas valve to check the pressure.
