Porous Metal Fluidizers

Porous metal stands out as the perfect material for fluidizing granulated solids or heavy materials for transport, making it a versatile fluidizer. When gas is passed through the porous metal media, it induces a distributed fluidizing effect on the combined material, creating hydraulic behavior akin to that of a liquid. This unique capability enables the seamless and efficient transport of the combined material to its intended destination, making porous metal fluidizers an essential component in various industrial processes.

Hardware Connections

A virtually infinite combination of hardware connections are available for design. We are capable of sourcing and assembling the connection you desire using years of experience and special equipment. For example, welding porous metal products is significantly different than solid to solid. If done improperly, blowouts can occur or leak paths can form if done improperly, causing waste and poor performance. Additionally, when assembling porous metal media into products, surface damage can occur which will dramatically impact the products performance. We’re experienced in all types of welding an assembly, use our manufacturing capability to your advantage.

Cleanliness & Treatment

Mission critical applications often require a host of unique properties and desired levels of cleanliness. Take advantage of our organic free processes and our Class 100 (ISO 5) and Class 10,000 (ISO 7) clean room manufacturing capabilities if your product and industry demands top cleanliness. In addition, post-treatments can be used to achieve additional performance characteristics, such as hydrophobic properties or additional strength. Some of these capabilities include:

– Annealing – ensure the best mechanical strength and corrosion resistant properties

– Surface Coatings – coatings such as silicone are used to achieve added properties

– Chemical Treatments – special chemical treatments such as surfactant treating add surface characteristics

– Passivation – get iron free cleanliness with nitric acid passivation straight out of the ASTM

– Organic Free Processing – let your product follow a unique process separate from regular production

– Advanced Joining – use our welding capability for oxidation free product
