Electric concrete internal vibrator VB series

Description
The electric concrete vibrator prevents the formation of air bubbles during concrete casting by transmitting high-frequency vibrations through a vibrating needle. It is designed to improve concrete compactness and site productivity while ensuring reliable operation in construction environments.

Details pictures / notes

• Stability of the vibrating needle is ensured by permanent magnet technology; the converter IR-C01 uses an aluminum motor and metal casing to reduce noise and vibrations.
• The VB ALFA vibrating needle operates with a cable range of approximately 30 m depending on site conditions.
