Automobile Catalyst
Product Overview
PRUITING® metallic catalyst, is using 0.05mm or thinner steel foil in the series of products, this leads to a further reduction in the exhaust gas counter pressure which improves the engine performance and decrease the fuel consumption.
Current product offer covers from 1.0" to 20" in diameter as a single catalyst for 3-way, DOC and other industrial applications, which would be perfect solution for gasoline or diesel engines displacement from 0.1 to 35 liters, the hole density from 100cpsi to 500 cpsi. As for the structure of core we have "Concentric circle " type & "S" type.
