Airless Spraying Components

Airless spraying has become exceedingly popular over recent years, this is due in part to the ease of application provided by this method and also the faultless finish provided. Due to this popularity there are now numerous varieties of airless paint spraying machines available, despite this diversity at their core these systems utilise similar components.

Airless Spraying Gun Tips:

Typically, a variety of different spraying gun tips can be utilised in conjunction with a single system, as different tips offer slightly different options, e.g. how much paint is applied. Also spray gun tips are often compatible for use with a number of different systems.

Therefore, prior to undertaking a task it is imperative to ensure that the optimum spraying gun tip has been selected, in order to provide the best results. Once the optimum tip has been selected it is equally important to ensure that the tip is compatible with the system you are using. For the most part, which tip is best the task at hand will largely be determined by the type of coating which you as using. To demonstrate, small tips are best for use with lighter coats, enamels and stains, whereas larger tips are better suited for use with heavier coats, such as latex.

Over time, however, a tip will become worn producing an inferior effect and will require replacement. One way in which you can tell that a tip has become worn is through a change in the pattern of the spray.

Airless Spray Pumps and Motors:

The overwhelming majority of airless spraying systems currently available make use of a pump. This is sometimes known as either the fluid system or a lower. The pump aims to ensure that an equal flow of paint is emitted from the system, even under high pressure.

In order for the pump to function a motor is utilised, which is either electric, pneumatic (air which is compressed) or hydraulic (pressurised liquid). Of these motor types, hydraulic and pneumatic are most efficient. This is due to the fact that they utilise either an air compressor or a hydraulic pump, these two systems provide a more even pressure control. This improved level of pressure control is due to the fact that the piston in these systems moves at a uniform speed.

What Is Airless Spraying? – CJ Coatings UK

Essentially, airless spraying is where an airless mechanism splits up liquid into small droplets. This process is a form of atomisation and is achieved by forcing the liquid up through a small nozzle which is known as a “spray tip”. As this paint is pushed up through the spray tip at a high pressure, there is enough energy to break up the surface tension of the liquid, which bonds it together. Therefore, all of the paint leaves the spray tip as a high speed stream. However, when it comes into contact with the air it fragments into tiny droplets.

Airless spraying has become the preferred method of decorating as it is suitable for use of a wide multitude of substrates. Its popularity can be attributed to the wide range of benefits provided when compared with traditional methods such as hand brush painting. The benefits include:

  • Airless spraying doesn’t leave any brush marks, unlike hand painting, which can be aesthetically displeasing.
  • An airless spraying system is portable and can therefore be utilised on-site provided spray painting as and where it is required.
  • Traditional painting methods, such as brushes and rollers, can take their toll on the painter’s back, arms and shoulders. However utilising airless spraying is physically easier on the individual making it preferable.
  • Airless spraying can be utilised on wide expanses, such as roofs, claddings and ceilings, when used in this environment it can coat the surface in one quick application with far less effort required than other methods.
  • Equally, airless spraying can be used effectively on much smaller surfaces which have previously been hand painted, these areas include metal door and window frames.
  • Airless spraying provides a means of application which is versatile in its using, meaning it can be equally effectively utilised on a wide range of internal and external surfaces, including architectural metalwork and UPVC window frames.
  • With airless spraying, surfaces and items can be sprayed to any colour and a wide range of surface finishes are available, including a number of metallic paint options.
  • Any and all surface flaws can be easily covered and filled with airless spraying, meaning that dents, holes and cracks in substrates can be cost effectively and quickly repaired with an application of paint.
  • Utilising the airless technique to apply paint is twice as fast as using a paint brush, whilst it is four times faster than using a roller. Therefore, utilising this technique enables for a far greater amount of work to be completed in a shorter amount of time, thus saving money.
