Concrete Vibrator GEKO WG-547 38 mm head, 4 m hose (model G80230)

GEKO WG-547 concrete vibrator with a 38 mm vibrating head and a 4 m flexible hose is a portable tool designed to consolidate freshly poured concrete and reduce trapped air. The compact vibrating head and medium-length hose make the unit suitable for on-site compaction tasks where access and maneuverability matter. This model is intended for small to medium concrete works such as foundations, pillars, slabs and repair jobs where improved concrete consolidation leads to higher density and better surface finish.

Advantages

The GEKO WG-547 features a slim 38 mm head that reaches narrow formwork and congested reinforcement, while the 4 m hose provides reach without excessive handling complexity. The portable design allows quick deployment on site and straightforward integration into common concreting workflows. The vibrator reduces the number of air pockets and helps achieve a more uniform surface, which supports stronger and more durable concrete elements when used according to standard compaction practices.

Suitable for

• Consolidation of concrete in foundations and footings
• Vibrating concrete in columns and pillars
• Compaction of slabs, floors and pavements in small to medium pours
• Repair and patching works where localized vibration is required

Key specifications

• Vibrating head diameter: 38 mm
• Hose length: 4 m
• Portable, hand-operated vibrator unit suitable for on-site use
• Designed for consolidation of fresh concrete to reduce air voids and improve surface finish

How to use

Insert the 38 mm vibrating head vertically into the fresh concrete at regular intervals, ensuring the head reaches slightly deeper than the required compacted level. Move the head slowly upward and downward or hold it stationary for short intervals until visible air bubbles cease rising and the concrete around the head appears dense. For linear pours, overlap insertion points to ensure consistent compaction. Follow standard safety and handling procedures for electric or petrol-driven vibrators and ensure the hose and head are kept free of debris after each use.

Usage recommendations

Use the vibrator in short, controlled durations at each insertion point to avoid segregation of aggregate. Maintain the hose and head in good condition; inspect before each use for wear or damage. When working in confined formwork or near reinforcement, use the 38 mm head to access tight spaces while observing safe handling distances from other workers and equipment.
