Emission Quality Solutions
We manufacture and customise Diesel Particulate Filters (DPF).

Product line
Diesel particulate filter

SMF-ER
We manufacture and customise quality Diesel Particulate Filters (DPF) that reduces diesel pollutant emissions for mobile machinery and stationary applications such as material handling machinery, underground mining equipment and urban transport, drill rigs, load haul dumpers, dump trucks and utility vehicles for underground mines.
Benefits of SMF-ER
- Constant monitoring of the exhaust backpressure and temperature
- Overload detection for the particulate filter
- Automatic indication that the filter needs to be cleaned
- Lower maintenance costs
Automatic regeneration

SMF-AR
Clean diesel emissions for mobile machinery and stationary applications. The SMF®-AR system filters the exhaust gases until an optimum
quantity of soot for regeneration has been collected in the filter.
The system makes use of the positive active properties of a fuel
additive that on the one hand lowers the soot’s ignition temperature and on the other hand increases its burn-off speed.
Benefits of SMF-AR
- Reduction of soot particles and fine particulate matter by more than 99%
- Suitable for OE and retrofitting applications
- Proven system already installed in more than 20 000 construction machines
- High ash holding capacity and low exhaust backpressure
- Low-maintenance and economical
- Reliable with long service life
- Easy DIY cleaning
LPG & diesel purifier

Reduce pollution
As a truck shifts heavier loads the more pollution it produces. However, with a purifier fitted the greater the load the more the pollution is reduced.
Continuous regeneration trap

SMF-CRT
Clean diesel emissions for mobile machinery and stationary applications.
Fume diluter

SMF-CRT
Diluters will dilute and cool hazardous engine exhaust gases to ensure that the operators are working in a healthier environment.
It will also reduce the risk of igniting nearby flammable or combustible materials due to lower exhaust temperatures.
For operators of vehicles within tunnels, containers and warehouses, diluters can be designed such that the exhaust flow is projected away from the vehicle or stationary equipment.
It is designed to withstand rough operating conditions for extended periods and have a low initial cost with minimal maintenance requirments.
Fuel born catalyst

SMF-FBC
The new sintered metal filter technology from John Ratcliffe can be used for mobile machinery and stationary applications.
