NetterVibration has acquired vast experience in the construction field, providing different models of vibrators as the Pneumatic Internal Vibrator Series NVV.
Pneumatic Internal Vibrators are designed to operate immersed in a fluid (concrete, sand, melt, etc.) and cause high-frequency circular vibration.
The internal vibrators are extremely reliable due to their simplicity. The circular vibration is generated by an eccentrically rotating rotor with a built-in lamella. When compressed air is applied, the lamella slides into the rotor guiding the air outflow evenly over the entire length of the rotor and forming a high pressure cell between the rotor and the housing which causes the rotor motion. Vibration power can be adjusted during operation via air pressure.
Features and advantages:
- Circular vibration
- High centrifugal force
- Adjustable speed
- High operating reliabiliabity due to simple and rigid construcion
- No bearings, therefore scarcely any wear
- Low maintenance
- Long lifespan
- Concrete compacting
