Catalyst Recovery – Batch filter

SEAMLESS DESIGN

Furthermore, GKN owns specific know-how to integrate a solid connection fitting into the porous part prior to the pressing process.
Due to the sintered joint, any further porous to solid welding seams are avoided.
This increases the strength and the reliability of the porous elements.

SIKA R..AS DESIGN

As a result of years of development, the product offers users a sintered membrane that combines high permeability and very low pressure drop, yet retaining all the advantages of sintered metal filters.
SIKA-R…AS denotes asymmetrically constructed metallic membranes.
Coating technic: The metal membrane is produced by applying a layer of extremely fine metal powder onto carrier of coarser porosity, such as the standard sinter. The subsequent sintering produces an even metal Coating of approximately 200 μm thickness so firmly bonded to the carrier as to exclude cracking and flaking in the layer.
Compared to the carrier support, the sintered layer has significantly smaller pore size, so that during filtration particulate matter is retained on the filter coating surface. The support structure (carrier) has no discernible influence on the filtration process and merely serves to ensure pressure loss remains low.
