SMF® - Sintered Metal Filter
The centerpiece of Stratus SMF-AR exhaust treatment systems is the Sintered Metal Filter (SMF), which has set new standards for performance worldwide. This filter reduces the emissions of soot particles and fine particulate matter down to the limit of detection, with a filter efficiency of over 99%.
The SMF and the systems based on it are exceptionally reliable in operation, require little maintenance, and offer a long service life. Stratus systems have proven their effectiveness over many years in more than 250,000 cars, buses, trucks, and heavy equipment.
The advantages of SMF™ technology result from its unique design and sintered metal construction. Exhaust gas backpressure is minimized by maintaining an unrestricted inflow of gas into the filter pockets from the outside. What’s more, the ash-holding capacity of the SMF is considerably higher compared to a conventional wall-flow (honeycomb) filter. This significantly increases the service hours before a filter requires cleaning, even with older machinery and
stationary engine applications that suffer from particularly high oil consumption. The costs of service and maintenance, as well as associated downtime costs, fall accordingly.
With their modular construction, Sintered Metal Filters can be adapted to suit different applications. They may be installed as original equipment (OE) or retrofitted to mobile machinery and stationary applications.
