Aeration Pads

Simultaneously aerating and vibrating bulk material, the low profile Coperion K-Tron aeration pads provide an effective flow aid for use when discharging all types of granular or powdered materials.

Air on

Air is introduced into the silo or bin through the aeration pad to aerate and fluidize the material. As air flows under the rim of the diffuser, it causes it to vibrate, helping move material that has a tendency to bridge.

Air off

When the air supply is switched off, the pressure of the material forces the specially designed diffuser against the side of the bin, preventing material from escaping under the diffuser and into the air supply line.
