The 4125 is our most powerful ionised air gun for neutralising static electricity and removing dust and other contaminants.

Built for performance

Best ionisation, best blow-off and best control for the most demanding cleaning


Full-hand trigger gives control without causing fatigue

Robust modular design

Built for a long life. All parts replaceable. Easy maintenance and repair.

The 4125 is our most powerful ionised blow-off gun for dust removal and neutralisation of static electricity.   Amongst other applications, the 4125 Air Gun is used throughout industry to clean mouldings, signs, graphics, lenses, mechanical and electrical assemblies as well as automobile painting, mirrors and windscreens.

With 5.5 – 6 kV of ionising power, the 4125 offers quiet performance and shockless operation.  The open air gun construction optimises the three essential functions:

  • External ionisation gives more static neutralisation power
  • Air nozzle amplifies compressed air by 20:1 for high thrust and cleaning efficiency with minimum air consumption
  • Ergonomic full-hand trigger for operator control without fatigue

Easy to repair and maintain, the 4125 is certified for use in cleanrooms to ISO Class 6.

The 4125 Air Gun is powered by Fraser HP Power Units which can serve from one to four guns.  Also cable tested for robot use to 9560 ETE 014800.


  • Air feed to top or bottom of Gun.

The best choice of product depends upon process speed, the distance of the static eliminator from the target and the level of static charge to be neutralised. Please get in touch for further assistance.


Stainless steel ionisation head and guard, PTFE ionising head, plastic handle, aluminium nozzle.


Purpose designed Hi-Flex HT cable is flexible, light and very durable. Standard lengths of 3 m, 5 m, 7 m and 10 m.


The ionisation system is shockless and meets OSHA and other safety standards, as the nozzle cannot be dead-ended.

Power Unit

Use with Fraser 5.5 kV or 6 kV Power Units - see separate Datasheets.

Air Supply

Maximum air pressure 10 Bar. Typical working pressure is 5 Bar. Air consumption at 5 Bar is 560 lit/min for continuous operation. Air must be clean and dry.

Air Connection

1/4” BSP threaded connection with 8 mm OD push-fit air fitting as standard. Use minimum of 6 mm ID supply pipe. If supply pipe is long use larger ID tubing.


At 5 Bar the thrust at a distance of 100 mm is a market leading 5.2 N (airspeed x volume which represents cleaning power).


At 5 Bar noise level is 74 dBA, measured at 1000 mm.
