Diesel Particulate Filter (DPF)

  • Reduces particulate matter (PM) by up to 85%
  • Operates from engine start-up
  • Non-Regenerative type filter
  • Suitable for standby generator sets, low-usage forklift trucks, side-loaders, excavators etc.
  • Bypass system available

The UGET3 diesel particulate filter collects the particulate matter in the exhaust stream by means of physical filtration. Effective from start-up, the filter is capable of retaining particles as small as 0.3 microns, trapping all PM10 and PM2.5 matter and is capable of reducing up to 85% of particulate matter (PM) in the exhaust stream. The UGET 3 is a non-regenerative type; it has a finite capacity of 1000 grams before the filter cartridge requires replacing.


The filter is suited to low usage applications such as standby generator sets or on equipment being used for short periods at a time, it is particularly suited to equipment being used in confined spaces. The filters can be bypassed, so that it is only used when required, i.e. inside tunnels and warehouses, electronic or manual bypass valves are available.

As the maximum operating temperature of the filter is 350°C, it is recommended that fitment of the filter is as far from the engine as possible, to avoid overheating. The filter can be bolted to the frame or body and simply attached with a length of flexible exhaust pipe. The filter cartridge is fire resistant and incorporates a heat shield for protection from burns.


There is minimal maintenance required, at the end of the filter life it is removed and simply replaced with a new one. Failure to do so will cause the filter to block, which in turn can damage or destroy the filter itself or cause damage to the engine due to increased backpressure.

Filter Life

300-350 hours depending on condition and maintenance of the engine.

Opacity Test

The graphs below shows the total percentage reduction at three different stages of a filters life. the tests were carried out using an 80kW supercharged engine.


Select the kW/bhp power from the figures in the table below and click on the correct model for your engine. For Turbocharged engines, multiply engine power by 1.3 and read directly from the table.

Special models can be produced for engines with larger power ratings, *UGET3 D40, D80 and D125 are available as vertical models, please contact us for details.

Case Study

This case study looks at how to reduce black smoke from diesel powered plant operating in confined spaces, in this case underground, in order to protect the workforce from harmful emissions.
