OLI – VH -Electric Poker

The range of electric concrete vibrators of VH is designed to work in direct contact with concrete to optimize compaction, for this reason they are also called immersion vibrators.
VH concrete pokers are capable of developing high centrifugal forces at a constant speed; the high wear resistance makes them suitable for all types of concrete processing, even in continuous operation in harsh conditions.


The high frequency immersion vibrators of the VH series allow the rapid removal of air bubbles trapped in fresh concrete without any segregation of the elements that make up the mass. The result is a homogeneous final product, durable and mechanically resistant, without cracks or cavities. The wide range available meets all needs in both the private and civil engineering sectors.


The high centrifugal force of the VH pokers is generated by a high frequency electric motor integrated in the vibrating needle. The control switch is protected by a reinforced gasket resistant to continuous use and is inserted in a polyamide housing with IP 66 protection.
The standard VH range has a 10 meter long electric cable and a flexible, internally reinforced control tube, 5 meters long.
For safety reasons, the VH vibrator range operates in very low voltage (42V), for this reason they must be connected to CM series electromechanical or EC series electronic converters.
