Sintered metal filter

The centrepiece of all HJS exhaust treatment systems is the sintered metal filter (SMF^®), for which HJS was awarded the 2003 German Environment Prize. The SMF^® is used to filter the exhaust gases emitted by a diesel engine – specifically to remove the ultra-fine respirable soot particles. The SMF^® is adapted to the specific requirements of the particular application. The filter system can take two forms: an 'open system' with particulate reduction rates of up to 70 per cent and a 'closed system' with reduction rates of over 99 per cent.

The specific properties of steel as a material mean the filters are robust, extremely heat-resistant and offer a long service life. These characteristics provide the ideal basis for use in different diesel engines. The range of potential applications covers diesel-engined passenger cars, light to heavy goods vehicles, buses, construction machinery, agricultural machinery and industrial trucks, but also stationary equipment such as power generators. Thanks to the inherent characteristics of its concept, the innovative filter can be installed as original equipment (OE) in new vehicles and machines or retrofitted to vehicles and machines already in service.

Without a shadow of doubt, this environmental protection technology is making an outstanding contribution to cleaning up diesel engine emissions all around the globe. And it's still gaining ground. In view of the increasingly stringent pollution control and emissions regulations being passed and enforced, the future belongs to SMF^® technology.
