RA 5 HV3


The automatic spray gun RA 5 HVLP impresses in the HVLP spraying process by its low-mist, environmentally-friendly and especially material-saving atomisation.

Field of application
The automatic spray gun RA 5 has been designed specifically for partly or fully automated coating processes. The field of application ranges from coating and marking surfaces to metering liquids and applying bonding and identification points. Typical coating materials include lacquers, paints, adhesives, glaze coatings,enamel, parting agents, etc. The RA 5 can be operated on a spraying robot, on a linear unit or firmly attached.

Spray gun change requires no tool

  • Spray gun change requires no readjustment for reproducible coating quality
  • Adapter system, including air and material connection
  • Easy maintenance
  • Needle and needle seal easy to change
  • Locking device detaches quickly
  • No setting dimensions to be observed

Air cap fastening, fastening positions can be changed in 45° steps, intermediate positions being possible Large material cross-sections, high-viscosity media or paints can be processed more effectively.

Mode of operation
The spray gun is activated by means of compressed air. For more precise activation, for example electrically activated solenoid valves can be used. This makes it possible to achieve switching times of about 60 ms. The coating material is atomised by means of compressed air.

The automatic spray gun is available in stainless steel or PTFE-coated aluminium, as desired. The connections at the adapter can be selected to be at the bottom or behind. The complete system is available as "quick-change" or as screw-type fastening. Moreover, the spray gun can be equipped with an air nozzle fastening, a needle stroke adjustment, a circulation connection and a double control. As a standard feature, needles are made from stainless steel, but are also available in hardened stainless steel, hard-chromed stainless steel or as hard metal. A large selection of different types of jets and sizes and extensions are available. Nozzles in special size and other special technical solutions on request.
