Pneumatic concrete internal vibrator PNU series

Product overview
PNU internal pneumatic vibrators are designed for concrete internal vibration on sites equipped with an air compressor. The units feature a cam-driven valve for maintenance-free operation, bi-directional rotation and an oil tank to support extended service intervals.

Applications
PNU vibrators are suitable for internal concrete consolidation in construction and precast settings where electricity is not available or where pneumatic tools are preferred. Their compact design facilitates handling in confined areas and across varied applications.

Benefits

• NO ELECTRICITY — Operates with an air compressor, eliminating the need for electrical supply on site.
• VERSATILITY — Available in multiple poker diameters (25–100 mm) and hose lengths (2–8 m) to match project demands.
• DURABILITY — Cam-driven valve and treated components with integrated oil tank for longer operating life.
• LIGHT AND COMPACT — Small footprint and reduced weight for easier maneuvering on site.
