Power Sources for Airless Spray Paint Guns

In this article, we will cover three of the most used mechanisms of power sources for use by airless spray guns.  It is a good idea to learn about the various types, so that it can help you make a better decision on which one is most suitable for your environment.   There are three kinds of sources: electric spray paint guns, pneumatic airless spray paint guns, and hydraulic airless spray paint guns. Here are some important points for your consideration.

  • Electric

Electric spray paint guns have an electric motor as its engine. An electric motor drives the piston in the paint pump. It is provided with a pressure sensor or a transducer which controls the starts and stops of motor as needed. Moreover, the speed of the motor can be changed through a digital control, due to how much paint the user wants to spray which result a very good control over the amount of pressure. This is the biggest advantage of these sprayers, having that various degrees of control over the amount of spray.

  • Pneumatic

In creating pressure, a pneumatic airless spray paint guns uses compressed air, which seems antithetical to the airless label that it carries. It has a pump with a piston that applies the pressure which is necessary to atomize paint. In order to create fine droplets, air spray paint guns put the air in direct contact with a stream of paint. The compressed air of a pneumatic gun instead powers the motor, which in turn drives the piston. Along these lines, this type of spray paint gun is also known as air-powered airless. This is often a good option for delivering a uniform pressure of the spray.

  • Hydraulic

This kind of airless spray paint gun uses a hydraulic pump to power the motor through the process of producing pressure via a piston or diaphragm as in electric and pneumatic models. The pressure which is resulted tends to be consistent since hydraulic pumps keep the motor moving in a constant way.  A consistent result is good of course to deliver a consistent film of pain to the designated surface.
