Wall-flow Filters

Blackthorn supplies wall-flow filter elements made from either silicon carbide, cordierite or fecralloy, in sizes up to 380mm diameter.

We can supply them either loose or canned, and also coat them with a catalytic coating which reduces the temperature at which they regenerate, as well as oxidising carbon monoxide and hydrocarbons.

Unlike some other suppliers, our coatings include a nanotechnology washcoat comprising alumina and rare earth elements. This enables more efficient operation whilst utilising lower loadings of expensive precious metals.

99% reduction in particulate matter, by mass
Coated filters also oxidise carbon monoxide and hydrocarbons
Nanotechnology washcoat facilitates low temperature regeneration without excessive quantities of precious metals
