Aeration Nozzles – also referred to as fluidization nozzles – direct air into bins, hoppers, or silos to solve material flow issues, like bridging and rat-holing, caused by design errors or by the characteristics of the powder or granules being handled. They are an economical, easy to install, and ideal for retrofitting.

Aeration Nozzles are an economical flow aid solution to ensure material flow from silos, bins or hoppers. An engineering polymer casing, co-moulded with a sintered nozzle (brass on U025; polyethylene on U060) has to be screwed onto a supplied steel nipple which previously has to be welded on the outside of the silo, bin or weigh hopper cone. Subsequently, connection with the compressed air supply has to be carried out.
U025 Aeration Nozzles are used with fine, dry powdery materials, such as cement, lime and similar powders, at an operating pressure of 0.2 bar (3 PSI), while U060 nozzles work at a pressure of 1 bar (14 PSI). Appropriate arrangements have to be made to exhaust excess air containing entrained dust at the top of the bin or silo.
Their small footprint makes Aeration Nozzles particularly suitable for retrofitting.
