Pneumatic Vibrator


Cosben Engineering’s pneumatic vibrator is designed to improve material flow and reduce common issues like bridging, rat-holing, sticking, and material build-up in bulk handling systems. In silos, hoppers, and bins, such problems can interrupt operations - this is where a reliable air vibrator or hopper air vibrator becomes essential.

Powered by compressed air, this industrial pneumatic vibrator delivers consistent vibration performance even in dusty or hazardous environments where electric solutions may not be suitable. It is widely used across industries handling powders and bulk solids, helping maintain steady discharge and smoother process flow.

From silos and chutes to feeders and conveyors, Cosben pneumatic vibrators support efficient material movement while reducing the need for manual intervention.

Key Features & Benefits:

  • Effective Flow Aid: Helps eliminate bridging, rat-holing, and material build-up.
