Airless Filter

The filter size for airless spraying, like the nozzle size, depends on the material to be processed. The function of the airless filter is to protect the airless nozzle from clogging. In addition, the airless filter can be found as the last filter variant before the airless application and is designed to filter out possible impurities in the paint material.

The airless filters are inserted into the airless gun as follows:

  1. The red airless plug-in filter has a mesh size of 200 meshes and is therefore very fine. It is used for low-viscosity materials such as oils, varnishes and release agents.
  2. The yellow airless plug-in filter has a mesh size of 100 meshes and is considered to be fine. These airless plug-in filters are used for low-viscosity emulsion and latex paints and anti-rust paints, primers and fillers.
  3. The white airless plug-in filter has a mesh size of 50 meshes and is therefore used for higher-viscosity materials such as roof coatings, corrosion protection, latex and emulsion paints.

Airless filters are used directly in the airless spray gun in airless paint sprayers.

An airless paint sprayer is used for the efficient surface coating of small and large projects and is therefore widely used by tradespeople, painters and varnishers, carpenters and joiners, and in similar trades.

Airless paint sprayers can be used to apply a wide range of different materials, from water- and solvent-based paints, facade paints, emulsions, rust protection paints, primers and fillers to heavy materials such as airless spray fillers.

The airless method thus offers users a very wide range of applications.

What is an "airless process"?

The airless paint spraying process involves a pump (e.g. piston pump/diaphragm pump) pressurising the material to be processed, pumping it through the high-pressure hose to the airless gun and finally to the airless nozzle, where it is atomised.

Since no additional air is required for atomisation, this is referred to as the "airless (airless) spraying process".

Which materials are suitable for application using an airless paint sprayer?

Airless paint sprayers can be used to process a wide range of low to high viscosity materials. This depends on the performance of the corresponding device.

The following materials, among others, can be processed using the airless paint spraying method:

  1. water-based or solvent-based 1 and 2-component paints
  2. primers
  3. primers
  4. stains
  5. fillers
  6. Interior and exterior emulsion paints, such as facade paints
  7. latex paints
  8. corrosion protection
  9. Airless spray putty and roof coating materials
