Gas hydraulic airless sprayer power comes from a gas engine to start the hydraulic motor that drives the fluid section. The benefit of using gas hydraulic airless sprayers is it has greater performance in pressure and flow rate.

Air motors are used for producing continuous rotary power from the compressed air system. These boast number of benefits over electric motors. 

The difference between high-pressure airless and air sprayers is the principle of air atomizing spray. High-pressure airless sprayers use pressure to atomize the paint sprayer, so the spray gun doesn’t need to rely on compressed air to assist in atomizing the paint.
