Product Description 

The VBS pneumatic bin aerator is a highly efficient flow aid system for silos and hoppers designed to improve the discharge of bulk materials such as cement, lime, flour, and plastic resins.

Installed on the lower cone of a silo or hopper, the aerator injects low-pressure compressed air through a flexible membrane, breaking up compacted material and preventing bridging or rat-holing. This ensures consistent material flow and faster unloading during plant operation.

Key Benefits

• Improves powder flow in silos and hoppers

• Prevents material bridging and clogging

• Reduces downtime during unloading

• Low compressed air consumption

• Easy installation on steel or aluminum silos

Typical Applications

The VBS bin aerator is widely used in:

• Cement silos

FAQ

What is a bin aerator?

A bin aerator is a pneumatic device installed on silos and hoppers to improve powder flow and prevent material bridging.

How does a pneumatic bin aerator work?

A pneumatic bin aerator uses compressed air and a flexible membrane to loosen compacted material inside the silo cone and improve discharge.

Where are silo aerators used?

Silo aerators are commonly used in cement silos, concrete batching plants, flour mills, and other bulk material storage systems.

Is this hopper flow aid suitable for cement silos?

Yes, this hopper flow aid is designed to improve the discharge of powders such as cement, lime, and fly ash in silo applications.
