Fresh concrete does not compact and release air bubbles trapped within the mix without vibration. Filquip supplies a range of Electric Concrete Pokers also known as Needles to overcome the poor fluidity and internal friction within the fresh concrete to release the air bubbles and compact the concrete mix.
These high frequency immersion vibrators come into direct contact with the concrete. The eccentric mass located within the needle is rotated through the protected electrical current to generate the vibration of the needle. The robust design and constant rotational speed delivered are critical to effective concrete consolidation. The 12,000 Vibrations per Minute speed is the tested ideal rate for proper concrete compaction.
OLI electrical concrete pokers are:
- 100% Waterproof
- Easy to maintain
- Free from Overheating
- Robust providing a long life for the vibrating needle head.
Vibration of the wet concrete also provides the following advantages:
- Reduction of cavities through the vibrational displacement of the aggregates to achieve a homogeneous concrete mix prior to setting.
- Greater adhesion of the concrete to the reinforcing bars or any internal structural members as well as the base anchors.
- Reduces concrete porosity and permeability to water.
- Reduces cracks occurring in the concrete.
- Completes filling of the whole formwork by increasing the fluidity of the concrete mix, resulting and higher aesthetic finishes of the concrete surface.

CM Electro Mechanical Converters for High Frequency
The CM Electro Mechanical frequency converters are equipped with permanent magnets, specifically designed to continuously power high frequency concrete vibrators.
In order to consolidate the wet concrete on the construction site, a light, flexible and easy-to-use tool is often required. One which can be connected directly to the common, single-phase power lines (240 Volt, 50Hz).
In order to solve this necessity, the CM range has been developed to convert the standard mains power into the high frequency power required by the concrete vibrators.
- Designed to power high frequency electrical concrete consolidation vibrators.
- Designed for Continuous Operation Class S1.
- Insulation Class F with Overload Protection.
- Smooth and Robust Cast Aluminium Body with Fan Forced Cooling.
- CMM11 Model 240V 50Hz Single Phase 11A
- CMM15 Model 240V 50Hz Single Phase 15A
- CMM25 Model 240V 50Hz Single Phase 25A
- CMT25 Model 415V 50Hz Three Phase 25A
- CMT35 Model 415V 50Hz Three Phase 35A
- CMT55 Model 415V 50Hz Three Phase 55A
- CMT85 Model 415V 50Hz Three Phase 85A
