DPF Cleaning

Diesel Particulate Filters are specifically designed for the control of fine particle particulate matter (PM) or smoke & associated harmful emissions from diesel powered engines.

Swift Industries Diesel Particulate Filters effectively reduces particulate matter (PM), carbon monoxide (CO), hydrocarbons (HC) & aldehydes (R CHO) into harmless carbon dioxide (CO2) and water vapour (H2O). In addition the Filter also reduces the otherwise normally obnoxious diesel smell.

Filter Performance

The following emission reductions are based on the engine running at 100% load:

  • Carbon Monoxide [CO]             ≤ 90%
  • Hydrocarbons [HC]                    ≤ 90%
  • Particulate Matter [PM]            ≤ 90%

    Diesel Particulate Filter applications

  • Diesel Gensets
  • Trucks and buses
  • Mining equipment and machinery
  • Tunnelling equipment
  • Lighting towers and access equipment
  • Construction equipment and forklifts

Exposure to Diesel Exhaust can have immediate health effects

Those most vulnerable are children whose lungs are still developing and the elderly who may have other serious health problems.

  • Ozone (precursors, NOx and VOC) eye and respiratory irritants, asthma exacerbation, bronchitis and irreversible lung damage.
  • Oxides of Nitrogen respiratory irritant, immunosuppressant and asthma exacerbation.
  • Carbon Monoxide headaches, irritability, impaired judgement and memory, breathlessness, aggravation of angina and other cardiovascular diseases, developmental toxicity and death.
  • Particulate Matter Respiratory irritant with higher levels associated with increased incidence of cardiovascular and lung failure.


As a DPF collects Particulate Matter (PM), the passage of exhaust gas through the pores of the filter element may be progressively blocked, causing an increase in exhaust backpressure.
Collected PM is combusted and reduced to ash during filter regeneration, effectively unblocking the pores of the filter element and decreasing exhaust backpressure. Normal filter operation will include fluctuations in exhaust backpressure; however, over time the accumulation of ash will gradually continue to increase backpressure.
Long term build-up of ash is remedied by periodic filter cleaning. In addition to PM, the filter also traps non-combustible materials resulting primarily from lubrication oil and fuel additives (ash). Cleaning of ash from retrofit DPFs is typically required every 6 to 12 months or 3000 hours. An engine emitting excessive PM or experiencing inadequate regeneration will cause a DPF to require more frequent cleaning.

Diagnostics should be performed to identify the cause for more frequent cleaning intervals. It is important to avoid excessive PM and ash accumulation in a DPF, so proper maintenance and cleaning instructions should be followed closely.
