Description
Advantages of airless spray are:
The coating penetrates better into pits and crevices.
A uniform thick coating is produced, reducing the number of coats required.
A very "wet" coating is applied, ensuring good adhesion and flow-out.
Most coatings can be sprayed with very little thinner added, thereby reducing drying time and decreasing the release of solvent into the environment.
Care must be used when operating, as airless spray gun can cause due to the serious injury from paint ejecting from the nozzle at high pressure. Airless pumps can be powered by different types of motor: electric, compressed air (pneumatic), or hydraulic. Most have a paint pump (also called a lower) that is a double-acting piston, in which the piston pumps the paint in both the down and the upstroke. Some airless pumps have a diaphragm instead of a piston, but both types have inlet and outlet valves.
Most electric-powered airless pumps have an electric motor connected through a gear train to the paint piston pump. The pressure is achieved by stopping and starting the motor via a pressure sensor (also called a transducer); in more advanced units, this is done by digital control in which the speed of the motor varies with the demand and the difference from the pressure set-point, resulting in very good pressure control. Some direct drive piston pumps are driven by a gasoline engine with pressure control via an electric clutch. In electric diaphragm pumps, the motor drives a hydraulic piston pump that transmits the oil displaced by the piston, to move the diaphragm.
