Wall-flow DPFs for Epiroc & Atlas Copco

  • Improved air quality for underground mine workers
  • An emphasis on direct-fit OEM integration
  • Enhanced performance for less downtime
  • Our process ensures quality and durability
  • We extend operational life with our DPFs
  • Savings on Total Cost of Ownership (TCO)

Do your Epiroc and Atlas Copco assets need DPF upgrades? For long-term asset management, it’s an essential consideration. With Aletek DPFs, you can improve machine performance and reduce Total Cost of Ownership (TCO) while reducing emissions for worker safety.

Epiroc DPF Upgrade Strategic benefits

  • Cleaner underground air with significantly less DPM
  • Direct-fit systems swappable with OEM Epiroc parts (no welding)
  • Highly durable 304-grade stainless construction
  • Robust plate steel rock covers
  • Best-in-class filters minimise servicing and regen temperatures
  • Maximum performance without backpressure headaches

DPF lifespans vary with site conditions, duty cycles, and operational factors such as flat tramming. Our DPF lifecycle enhancements often result in 30-40% savings in TCO compared to competitor products. Using Aletek DPFs can also improve productivity and machine performance.

Aletek filters are a breath of fresh air

With almost a decade of experience in emission control, we can help you get more out of your underground fleet of Epiroc haul trucks, loaders, and drill rigs. We use industry-leading substrates in our DPF systems to help mitigate power loss and backpressure concerns.

  • Aletek wall-flow DPFs capture >99% DPM
  • Superior filters with a regenerative catalyst coating
  • High-capacity filters store more soot (less frequent servicing)
  • High-flow filters mitigate power and backpressure issues
  • Longer service life and lower cleaning costs

Our benchmark upgrades for Epiroc

Aletek wall-flow DPFs are better by design with arguably the best filters. We fabricate our rock covers and DPF housings with heavy-duty steel to withstand mining operation adversities. Rotatable frames are also available to protect your DPF during transport.

We are known for our tailor-made thermal insulation blanket kits. The use of blankets can reduce heat transfer and protect exposed hot parts from hazards. Our custom lagging solutions can protect your DPFs.

We also offer OEM replacement mufflers and engine pipes. For assets that cannot regenerate a wall-flow DPF, partial DPF solutions may be an option.

Machine-based DPF showcase

Optimise the efficiency of your Epiroc machines with Aletek DPFs. Below is a list of our most popular solutions.

  • Drill rigs: DPFs for boomers H1257, Epiroc T1 D and S1 D
  • Underground loaders: Ask about our ST18 DPF
  • Underground trucks: DPFs for Atlas Copco MT series and Epiroc MT series mine trucks, including Epiroc MT54 & MT65.

DPF systems from Aletek typically last significantly longer. Longer lifespan and other performance factors translate into lower ownership costs. Some sites have reported savings of up to 50% compared to competing products.

OEM compatible upgrades


Crews can easily swap out or upgrade parts with our OEM-compatible DPFs and components. Aletek direct-fit DPFs are an excellent choice for improving Epiroc engine performance. We also offer upgraded Epiroc parts including mufflers, engine pipes and tailor-made thermal lagging packages.


We specialise in direct-fit DPF upgrades for Epiroc and Atlas Copco equipment. In addition to improving machine performance, our DPFs significantly reduce DPM to ensure worker safety. DPF systems are available for boomers, scoop trams, and mine trucks. Ask about our flagship MT65 DPF upgrade.


Aletek heavy-duty muffler upgrades are high-temp powder coated to protect against corrosion and general wear. Our solutions include MT5020 and MT6020  replacement mufflers and 1257 drill rig mufflers. We have a proven track record of building superior OEM upgrades.


Aletek designs and manufactures engine pipes that connect our DPF upgrades to the turbo outlets. Our universal pipe is an excellent OEM upgrade for MT5020, MT6020, MT54 and MT65 trucks. For pipe installation, we also supply OEM-compatible brackets and V-band clamps.


Thermal lagging helps prevent engine fires. In addition, it minimises heat dispersion from DPFs and engine pipes. We can provide custom thermal blankets for your Epiroc DPFs and turbo, manifold and engine pipe lagging. We offer blanket kits such as M2D, MT6020, MT65, S1D and T45.

Drill Rig Boomers

You can improve the performance of your Atlas Copco and Epiroc underground drills by upgrading to Aletek DPFs. We have purpose-built DPFs for drilling boomers such as H1257, T1 D, and S1 D. We specialise in direct-fit DPF systems.

Underground Loaders (ST series)

Invest in Aletek DPFs for your Epiroc ST loaders to prevent downtime. Our ST8 DPF system is one example of how we can add value to your Scooptrams. Get in touch to learn about our custom solutions to enhance your DPFs and meet your emission and performance targets.

Underground Trucks (MT series)

Epiroc and Atlas Copco Mine Truck DPF upgrades are our forte. Our range includes purpose-built systems for Atlas Copco MT5020 and MT6020, as well as Epiroc MT54 and MT65 DPFs. One of our signature upgrades is our MT65 DPF upgrade with rotable frame and Stage V options.
