Binderless stainless steel sphere powder filter


Do not use mix during molding (binder less) A new stainless steel filter has been made.

For general SUS sintered filters, mix binder and wax of material powders to prevent wear of the molds and shape deformation of molded products after pressing. However, they may remain inside the filter as residues after sintering, which can adversely affect the performance of the filter.

Since the “binderless stainless steel spherical powder filter” developed by our company is molded and sintered without using any mixtures, impurities will not remain after completion.
It is ideal for analytical instruments and fuel systems that require higher purity filtrate.

· Comparison of flow rate (equivalent to nominal filtration hole 10 μ / cup type / thickness 2 mm sample)

Type Water flow rate(ml/min.) Air flow rate(ℓ/min.)
General sintered filter (using heterogeneous powder) 26 370
Binderless sphere powder filter 31 651
About 20% UP!! About 40% UP!!

Our SUS spherical powder filter uses SUS spherical powder as a material and it has very low pressure loss compared with conventional general SUS sintered filter and can reduce the burden on peripheral equipment.
