Manual rotor jets

Manual rotor jets

Rotor jets convert the high effectiveness of round jet nozzles into area performance through rotating nozzle heads. Various nozzle configurations and adjustable speeds open up many possibilities for surface treatment. The lightweight and compact design also enables work in areas that are difficult to access.

Affect the removal result

The great advantages of the MASTERJET can be seen in the ability to adapt quickly to changing work situations as well as in the controlled influence on the removal results. From gentle cleaning to strong removal, everything is possible. In order to adapt the removal result to the job requirements, two different work steps can be followed, which can be carried out independently of one another. Option 1: Hammelmann offers various nozzle holders with different configurations and designs. The rotor jet can then be equipped with 2 or 4, 3 or 6 or 5 nozzles, depending on the nozzle holder. Option 2: The rotational speed can be adjusted independently of the nozzle configuration simply by moving the outer sleeve (magnetic brake).

The right nozzle configuration

The different nozzle configuration of the MASTERJET allows the use of 2, 3, 4, 5 or 6 nozzle inserts. The MASTERJET rotor jet thus offers a wide range of possible uses and proves to be a unique all-rounder in practice. The following rule applies here: the more nozzles there are, the more the force is distributed over the surface being processed. The force acting on the surface is therefore less with a 6-jet application than with a 2-jet application. With just one MASTERJET, sensitive surfaces can be gently cleaned and concrete surfaces in need of renovation can be roughened and removed.

 
 

Full braking effect / Slow speed

Half the braking effect / Medium speed

No braking effect / High speed

 
 
 

Simply adjust the speed by hand

The speed is set by simply moving the outer sleeve. A copper strip in the outer sleeve then overlaps a rotating magnet inside either completely (high braking effect), halfway (medium braking effect) or not at all (no braking effect). With this simple movement, the speed can be adjusted quickly and easily, regardless of the nozzle hub. The further the outer sleeve is pulled towards the nozzle hub, the slower the nozzle holder rotates and the more the surface is processed, as the water jets stay longer in one place.

 
 

Typical applications and areas of use

Efficient renovation and maintenance of concrete with the MASTERJET

 
 

Thorough and quick cleaning of small and large concrete surfaces

Sometimes it can be enough to thoroughly clean concrete surfaces in the course of a renovation if they are neither damaged nor weathered. We have developed product solutions to treat both small and large areas thoroughly and safely. The product range extends from hand-held high-pressure blasting guns to ergonomic work aids and high-pressure surface cleaners.

Roughen concrete surfaces - from fine to coarse

A high-pressure blasting gun can be used in combination with a rotor jet for roughening different concrete surfaces. Equip your MASTERJET with 2, 3, 4, 5 or 6 inserts and decide the degree of roughening yourself. The amount of water is evenly distributed over the number of nozzle inserts. With 6 inserts, the individual jet exerts significantly less force on the target surface than with 2 nozzle inserts. According to this rule, you can decide for yourself how you want to roughen the surface.

Treat a wide variety of surfaces gently and thoroughly

Cleaning surfaces of all kinds gently and thoroughly is one of the regular tasks in a wide variety of industries. The removal of dirt, residues and deposits with high-pressure water offers many advantages. The process low impact on the surfaces and is environmentally sound, and cleaning with high-pressure water in combination with our manually operated rotor jets offers more application options than almost any other system.

Decoating and stripping

 
 

Decoating and stripping

Effective removal of paint layers of various qualities with high-pressure water has become more and more established over time, as it is an extremely gentle yet thorough process that does not damage the base material. This work can be mastered excellently with MASTERJET rotor jets. The pressure and the removal rate can be easily and quickly adapted to the hardness and nature of the coating. Thanks to the adjustable working pressure, water is completely sufficient as a medium without the need of adding abrasives. In connection with high-pressure pumps from Hammelmann you get an unbeatable system!
