Principal of Operation

When powders are conveyed into a bin or other type of vessel most often the material is pneumatically conveyed. As the material flow enters the bin it is a combination of air and particulate. As the particulate settles, the air escapes. While some materials and bins freely flow, others require assistance. The disc aerator or fluidizer loosens up the material allowing it to flow by adding air back into the material and by creating a gentle vibration of the disc.


BlueLevel Technologies now offers a unique disc fluidizer that forces air to move along the bin wall freeing up the material and assuring good bin cleanout. The disc also vibrates which keeps the material flowing without allowing it to compact or plug. The disc seals tightly against the bin wall and prevents airline plugging. The disc is robust and will not tear, absorb moisture and operates with temperatures up to 350° F (175° C).

Application and Use

The disc aerator is designed for use with compressed air systems, not blowers, and promotes the flow and discharge of powder materials from bins, hoppers and silos by inserting air into the material sweeping along the bin wall and creating a gentle vibration.


The effective range of each disc aerator is approximately 10-12" radius. Mounting can be from inside or outside the bin (requires use of external mounting kit accessory).
