Sorting out servopneumatics
. Hydraulic pump systems cost more than air compressors, and hydraulic components must be built to withstand higher pressures, so hydraulic drives can be several times more expensive than pneumatics. Maintenance costs of pneumatics are also lower, while life expectancy of all three systems is about the same
