Diesel Particulate Filters (DPF)

Developed in Denmark, more than a decade ago, the Notox Silicon Carbide Diesel Particulate Filters, have been proven as an excellent solution for demanding retrofit applications, where a very durable filter substrate is required. Where other filter substrates consequently fail, Notox has succeeded with the R-SiC filters.

Our filters are manufactured in two different versions, each targeted for different application fields and in particular different regeneration strategies. With these two main versions of the filter available, an optimized filter solution is available for almost any application.

A catalytic coating can be added to any of these versions. However the Notox XD-90 version has proved to be very suitable for coating due to the larger pore size of this filter.

The XD Filters

these filters for filter systems with a passive regeneration strategy, where the filter may encounter very high soot loads before regeneration takes place.

During regeneration of elevated soot loads, the filter structure experiences high stress levels due to the energy release from the soot combustion. Our XD filters can withstand regeneration at soot loads above 15 g/l without being damaged.

The MD Filters

The Notox MD filters available in 200 CPSI are targeted towards systems with active regeneration or OEM use, but can also be applied for passive systems with consistent regeneration. For this type of applications, where regeneration takes place under controlled conditions, a filter with less durability is sufficient. This enables a filter design with more attention on reducing the pressure drop as much as possible. The maximum allowable soot load is however still as high as 10 g/l.

Sizes Available

We manufacture the filter substrates in almost any standard size required on the market from 4,66” to 15” diameter.

We are also able to deliver square, oval and race track shapes or any other cross section specified by our customers.

If your specific application requires a filter with a non-standard cross section or just a standard cross section in a non standard length, we are pleased to offer our service to you.
