- Increase service life and save on TCO

A Game-Changing Solution
Turn DPF Pain into Gain
Don’t let substandard DPF performance affect your underground productivity. High backpressure leads to higher maintenance costs and performance issues. Our systems, featuring best-in-class filters, capture over 99% of DPM while using high-flow substrates to mitigate power loss and extend service life.

Why Choose Our DPFs for Your CAT Fleet?
Our DPFs provide a dual benefit: they ensure a safer working environment by significantly reducing DPM, and they lower your Total Cost of Ownership. With an expected product lifecycle of up to 20,000 hours and reduced maintenance needs, you'll see a tangible return on your investment through increased productivity and lower costs.
Our filter technology is our key advantage. We use high-capacity, wall-flow substrates with a superior regenerative catalyst coating. This allows our DPFs to trap over 99% of particulates while maintaining high exhaust flow, which solves common issues like power loss and high backpressure that plague standard filters.
Yes. They are specifically designed for the harsh realities of mining. The DPF housings are made from durable 304-grade stainless steel, and we offer robust, 6mm plate steel rock covers for added protection. Optional rotable frames are also available to protect the filter during transport and handling.
Absolutely. We offer a complete, integrated solution. This includes heavy-duty mufflers, direct-fit engine and exhaust pipes, and custom-made thermal insulation blankets (lagging) to protect your DPF and surrounding components from heat and potential fire hazards.
