Commonly available airless spray equipment systems can be powered by a variety of means and are offered in a wide range of sizes and performance capabilities.

• Hand held cordless electric airless spray guns battery powered.
• Hand held electric airless spray guns mains powered.
• Hydraulic diaphragm mains electric or petrol powered airless spray pump equipment.
• Mains electric powered reciprocating piston airless spray pump equipment.
• Petrol engine powered reciprocating piston airless spray equipment with electric clutches.
• Hydraulic powered airless piston pumps using either electric motors or petrol powered motors to provide hydraulic power.
• Pneumatic compressed air driven reciprocating airless piston pump equipment.

Airless spray systems in any of the above categories atomise fluid or liquid including paints and coatings by forcing the fluid through a small nozzle or orifice at high pressure. As the liquid passes through the small nozzle or airless spray tip at high pressure the liquid is atomised into a fine spray. The effect is similar to restricting the flow of water from a standard garden hose by placing your finger over the end of the hose and restricting the flow of water until the water becomes a spray of water.

Never place fingers or any other body part near any outlet on an airless spray unit as the extremely high pressure can cause serious injury.
