Caterpillar is a global Original Equipment Manufacturer (OEM) of heavy mobile machinery, technologies and services for the mining industry. Minetek optimises Caterpillar mining equipment and exhausts, helping to reduce machine noise and overall sound power levels. From underground mining equipment to surface mining machines, Minetek can attenuate any diesel machinery; from excavators to drill rigs, loaders to haul trucks, graders, dozers & more. You can be confident you are getting the best possible sound-reduction products and Caterpillar exhausts on the market.


  • Machine performance is not hindered
  • No overheating or equipment failure
  • No excess vibration resulting in excessive noise
Caterpillar exhaust muffler

Caterpillar Exhausts & OEM Mufflers

Minetek manufactures noise-cancelling exhausts and sound-reduction mufflers for Caterpillar mining machinery. We understand the importance of high-quality mining equipment and the impact machine noise has on operations and production. That is why Minetek provides a comprehensive selection of machine noise reduction solutions across a range of OEM models, including Caterpillar, Liebherr, Komatsu and Hitachi equipment. Our solutions help operators mine efficiently without exceeding or breaching regulatory noise levels and restrictions.

Each element of Minetek's Caterpillar exhaust/muffler is specifically designed with sound reduction properties that vary with the machine's acoustic frequency. It is the mixing and matching of these elements that underpin the engineering of Minetek’s Caterpillar muffler design. With cutting-edge technology and innovation simulation programs, Caterpillar exhausts can target specific frequencies, including balance tubing and noise-cancelling tubes.

Caterpillar Mufflers & OEM Mining Machinery

Caterpillar enables mine sites to operate safely and productively with a range of underground and surface mining machinery available. Although diesel equipment provides efficiencies, they emit high levels of noise which put the operator at risk of excessive noise exposure. In addition, this machinery may exceed noise limitations impacting nearby residents and the community. Minetek's Sound Attenuation targets and treats noise from the source, with Caterpillar exhausts and sound suppression mufflers utilised for exhaust noise control.

We work with OEM's such as Caterpillar to produce the world's quietest and most efficient mining machinery. With over 1500+ machines attenuated our sound attenuation solutions can help reduce noise levels by up to 12dBA. Our noise reduction solutions are engineered to maintain productivity and minimise the impact on operators and maintenance teams. Minetek’s modular sound suppression kits are available for Caterpillar mining trucks, excavators, dozers, loaders and drills, with certified install teams available globally.

Sales Enquiry


MINETEK initially provided products for heavy mobile equipment noise abatement at the New Acland Mine. These installations have been very successful and prompted the contracting of MINETEK to conduct a full mobile fleet and fixed plant noise monitoring assessment at the Acland mine site.

New Hope Group Project Superintendent

The ability to deliver equipment on time has been a feature of our dealing and we haven't had a situation where a variation has been requested. The quality of their workmanship has been good and the capability of hardware has been as expected or better than quoted”

CS Energy Kogan Creek Power Station Services Superintendent

We found the MINETEK WATER team listened and supported our situation with helpful guidance and advice to layout the evaporator pipework maximising their efficiency. I would highly recommend the units to others needing a cost effective solution to excess water.”

Osborne Gold Mine Superintendent Environment

It was completed with no incidents or injuries, with no delays, and ahead of schedule. The plan was for 10 shifts, and it was completed in 7 shifts.

Northern Goldfields Mining Manager

We are always looking at new innovations and technologies that will benefit both us and our clients. Minetek has been able to display that with the use of their modern ventilation technology, where we can look to see production increases through faster re-entry times and reduced capital costs in the total life of the development, delivering value to both us and Mincor.
