What is Airless Spray Painting?

When compared to spraying with compressed air, what is airless spray painting? To put it simply, Airless spray painting just uses material pressure without the air. An electric or pneumatical pump or petrol engine places the material under pressure and forces a defined amount of material at a maximum pressure of 250 bar through a tip bore. This transforms the material into a spray.

How do Airless paint sprayers work?

  1. A pump is used to bring the paint material to a pressure of up to 250 bar and then through an airless spray gun.
  2. When the paint valve (gun) is opened, the paint is forced through an opening in the airless tip of the right size relevant to the requirements. Atomisation is created through the pressure difference between the coating material and the atmosphere.
  3. The flow rate and spray jet width are determined by the tip.

Note:

Please note that our airless paint sprayers work with different pressures and therefore not all materials can be processed with every machine. For highly viscous materials, for example, you need a strong piston pump from the contractor range. For wood and metal paint and emulsions for example can be applied with our DIY airless paint sprayers. You can find out which machine is suitable for your needs on the DIY page Airless sprayers for do-it-yourselfers and for the trade machines on the product pages.

What is the difference between a paint roller/brush & airless paint sprayers?

Rolle

Paint roller

+ Quick cleaning
− Paint application takes longer
− Transporting of materials is hard work
− Scaffolding needs to the climbed multiple times
− Repeatedly moving material over large areas
− Masking is also required
− Low and uneven covering capacity on a dark surface
− Multiple roller applications are required to cover a dark surface

Pistole

Airless Paint sprayers

− Cleaning takes longer
+ Paint application is faster
+ Material remains on the ground
+ One-off climb with the gun and hose onto the scaffolding
+ No material moving thanks to long hose length
+ No added work for masking
+ Good and even coverage on dark surfaces
+ Even coverage on textured surfaces
