The difference between pneumatics and hydraulics actually lies in the medium that is utilised to transmit power. Pneumatics use easily-compressible gas like air or pure gas. Meanwhile, hydraulics utilize relatively-incompressible liquid media like mineral oil, ethylene glycol, water, synthetic types, or high temperature fire-resistant fluids to make power transmission possible.

Because of this primary difference, some other aspects about these two power circuits also follow suit. Industrial applications of pneumatics utilize pressures ranging from 80–100 pounds per square-inch, while hydraulics use 1,000–5,000 psi or more than 10,000 psi for specialized applications.

Moreover, a tank would be needed in order to store the oil by which the hydraulic system can draw from in cases of a deficit. In a pneumatic system however, air can simply be drawn from the atmosphere then purified via a Festo Filter Regulator.
