MODEL RA
Bin Aerator
Affordable Aeration!
Efficient, low cost aerator pads promote flow to enable proper material level control.
Ensuring proper material flow of powders and bulk solids within bins, hoppers and silos is important to proper bin level indication, level control and level sensor operation. Ratholing and bridging can occur in many situations, leading to false level control and level sensor indication, as well as production problems. Bin aerators introduce air back into powder materials to restore the material to its naturally aerated state and allowing it to flow readily.
The Model RA is provided in a rectangular size that is standard within concrete batching plants and other industries. Construction is of zinc-plated steel with a fiberglass diffuser material and an external mounting kit accessory.
Low cost – affordable aeration
Keep material moving – enable proper level control
Promote material flow naturally – no damage
Heavy-duty construction – withstands rigors of concrete batch plants
Fiberglass diffuser – resists clogging
External mounting kit available – simplifies installation

Principal of Operation
BlueLevel Technologies helps industry monitor and measure the level of powders, granular and liquid materials in a wide variety of vessels. Accessory items such as the Model RA bin aerator are available to promote and maintain the flow of material so that proper level control and measurement can be ensured. Operating on a wide range of powders and bulk solids the Model RA bin aerator promotes the flow of materials from bins and silos using the proven principle of aeration. As the material in your bin settles, air escapes and the material packs and behaves as a solid mass. The Model RA is a heavy-duty aerator provided in the industry standard rectangular size of 3-3/4″x 7-1/2″ and is used to introduce low pressure air into the material in the bin, thereby restoring its natural aerated state allowing the material to flow. In this manner bridging, ratholing and other material flow problems can be resolved and proper bin level indication and control ensured.
Application and Use
Aeration of powders in the cone sections of bins and silos provides best results with materials of 60 mesh size and smaller, and with 3% moisture content or less. The area of effective operation per aerator is approximately 20″ diameter. The Model RA bin aerator works well to promote the flow of cement, flyash, lime, carbon black, flour, soda ash, diatomaceous earth, gypsum, soap powders, clay and many other materials.
