Sprayer FAQs Send this page to a Friend Airless spray systems atomize coating by forcing a fluid through a small orifice at high pressure. They are prized for their high production rates that can exceed 2 gallons per minute for larger models. Airless sprayers provide pressure from either a diphragm or piston pump unit driven by an electric, gasoline, or air power motors.
Some models use a hydraulic driven pump powered by electricity or gasoline power.
The hose is an integral part of the system. Its expansion and contraction provides volumetric cushioning of the fluid to provide steady paint flow at the tip. It also conducts static electricity build up back to the sprayer where it can be grounded. Many companies use one pump on a variety of models. The difference comes from the motor and powertrain with changes in horsepower or motor type.
