Airless paint sprayers do not require a compressor or turbine to push the paint out of the system. Instead, they employ high-pressure air, gas, or electricity to distribute paint throughout the surface of your product. This article explains all you need to know about the Airless Spray Painting Machine.

What is an Airless Spray Painting Machine?

Airless spray painting employs material pressure instead of air. An electric or pneumatic pump, or a gasoline engine, applies pressure to the material and drives a certain amount of material through a tip hole at a maximum pressure of 250 bars. This turns the substance into a spray.

How Do Airless Paint Sprayers Work?

  • A pump is used to increase the pressure of the paint substance to up to 250 bar before passing it via an airless spray cannon.
  • When the paint valve (gun) is opened, the paint is pushed through an aperture in the airless tip that is the appropriate size for the needs. Atomization is caused by the pressure differential between the coating material and the atmosphere.
  • The tip determines the flow rate and breadth of the spray jet.

What materials are suitable for airless paint sprayers?

Various materials can be sprayed with Airless Spray Painting Machines. We have compiled a summary of them here.

  • Paints, varnishes, lacquers, oils, and separating agents made with water or solvents
  • Synthetic resin-based paints, PVC paints
  • Primers and Fillers
  • Fireproofing and corrosion prevention paints
  • Emulsion, latex paints, adhesives, and sealants.
  • Masonry paint, roof linings, floor coatings, and silicon resin paint
  • Fillers and other very viscous materials

Benefits of Using an Airless Spray Painting Machine

Airless paint sprayers offer three significant benefits over paint sprayers that use air compressors:

  • Portability: An airless paint sprayer is more portable than regular sprayers. Airless paint sprayers are perfect for job sites and tasks that need a big surface area or are difficult to spray. 
  • Paint finish: Airless paint sprayers produce a smoother finish than other alternatives.
  • Pressure: Airless Spray Painting Machines push a steady stream of high-pressure paint through the nozzle, whereas typical sprayers require an associated compressor to produce pressure. 

Types of Airless Paint Sprayers 

Airless paint sprayers are commonly classified into three kinds based on the power source:

  • Pneumatic Paint Sprayers
  • Electric Paint Sprayers
  • Gas-powered paint sprayers

Pneumatic airless paint sprayers.

Contractors and industrial site managers like pneumatic airless paint sprayers because of the variety of nozzle sizes they may utilize. Different coatings require different nozzle diameters to be applied. 

Pros: 

  • Adaptability: Compatible with different nozzle-based equipment for contractors. 
  • Safety: Safe in dangerous situations (e.g., explosive or toxic). 
  • Versatility: Able to use a range of nozzle types and spray guns. 

Cons: 

  • Loud: The loudest choice.
  • Environment-specific: Not suitable for colder conditions (can freeze).

Electric, airless paint sprayers

Electric airless spray painting machines are an excellent choice for smaller, domestic contractors who may not require the power of a gas or pneumatic airless sprayer. 

Pros: 

  • Quiet: The quietest of all power categories.
  • Energy efficient: Lowers the cost of utilizing the paint sprayer.
  • Multi-environmental: Can be utilized in chilly conditions.

Cons:

  • Pressure: Lower PSI than the other alternatives. 
  • Battery limiting: Must be plugged in or charged. 
  • Nozzles: Use only tiny nozzles.

Gas-powered airless spray painting machine

Gas airless paint sprayers are another excellent choice for industrial contractors. However, they are restricted by explosive conditions and require licenses on some project sites. 

Pros:

  • Portability: Gas airless paint sprayers are the most portable and built-in power source.
  • Pressure: the highest PSI compared to the other power sources.
  • Power: Capable of handling the hardest jobs.

Cons:  

  • Environmentally limited: The power source is not permitted in chemical or explosive settings.
  • Permits: Permits are required on specific job locations.
