VHN are Electric High Frequency Internal Vibrators for concrete compaction.
The VHN range is characterised by high centrifugal force, constant speed and high wear resistance which makes it suitable for all types of concrete processing, even in continuous operation.
Technical Specs


VHN Electric High Frequency Internal Vibrators (standard range) consist of a tractor unit called vibrator head, 10 metres of electric cable and of 5 metres internally reinforced operating hose.
The high centrifugal force is generated by a high frequency electric motor integrated in the vibrator head.
Vibrators are equipped with a key pad (IP 66 protection) in polyamide, complete with switch protected by a reinforced gasket resistant to continuous use and wear.


Highly increased compacting capacity enables quick removal of air bubbles without any segregation of the elements composing the mass. The result is mechanically strong, durable and homogeneous concrete strength with no cracks or cavities.
