Mammoth Equipment & Exhausts is a premier global solutions provider dedicated to improving operations and safety on mining equipment world-wide through industry leading solutions and systems. We have worked closely with mines for decades to engineer products designed to minimize equipment downtime, reduce the risk of fire or DPM exposure, and extend the life of heavy-duty machinery, all while maintaining our commitment to sustainability.
From thermal covers and direct-fit replacement exhaust parts to emissions solutions and sound attenuation products, Mammoth delivers proven performance where it matters most to your operation.
Fire prevention and heat control solutions
Mining machinery runs hot, turning minor leaks in oil or fluid lines into serious threats to mining operations. Mammoth’s Thermal Cover systems (sometimes referred to as thermal blankets) are designed to stop fires before they start. Each cover provides multi-layer insulation that reduces surface temperatures by up to 85%, protecting operators, hoses, wiring, and critical systems from dangerous heat exposure.
Our thermal covers are perfectly fit for every application, using a combination of embossed stainless steel, silica fabric, and fluid-resistant coatings to withstand extreme temperatures, oil ingress, and pressure washing. When partnering with Mammoth for your fire prevention needs, we offer thermal audits and advanced imaging to help identify hidden fire risks and deliver measurable improvements in site safety and uptime.
When working in extreme cold, Mammoth’s FreezeGard systems extend protection into sub-zero environments, preventing freeze-ups on pipes, hoses, and DEF tanks to keep machines running even in harsh winter conditions. Designed for easy installation, removability, and reusability, they’re a cost-effective safeguard against downtime and equipment damage.
Equipment/direct-fit replacement solutions
Mammoth Equipment & Exhaust manufactures direct-fit replacement exhaust and air intake systems engineered for the realities of heavy-duty mining and industrial environments. Every component—whether it’s a muffler, pipe, bellow, flange, or airbox—is reverse-engineered from OEM specifications and improved through precision design to deliver a perfect fit, exceptional durability, and consistent performance.
From turbo to tailpipe, Mammoth’s exhaust systems deliver superior reliability, heat control, and efficiency. Each component is built from high-grade aluminized and stainless steel, with options for single-wall and dual-skin configurations. Dual-skin exhausts isolate internal heat, lowering external surface temperatures by up to 150°C, minimizing burn risk, and preventing fire hazards around fuel or hydraulic lines. Every weld, flange, and joint is optimized for long service life, with machined flanges, reinforced bellows, and precision bends that improve airflow and reduce stress points common in OEM or lower-grade replacements, to deliver an integrated, high-performance safety solution from end to end.
Air intake solutions
In addition to exhaust, Mammoth’s Air Intake assemblies are engineered to extend filter life and maintain clean airflow even in the harshest mining and industrial conditions. Our systems include stainless steel airboxes, precision-fit piping, rubber components, and high-efficiency pre-cleaners that protect engines from dust, moisture, and particulate buildup.
We offer axial-to-radial seal upgrades, complete kit packages, and compatibility across multiple machines makes and models. These upgrades deliver measurable benefits such as less maintenance, longer service intervals, and improved fuel efficiency, all while ensuring compliance with your site’s air quality and performance standards.
Emissions control solutions
As mining fleets evolve, emissions management has become both a regulatory and operational priority. Mammoth’s Diesel Particulate Filters (DPFs) and emissions control kits capture up to 99% of diesel particulate matter, helping underground mines achieve compliance while improving air quality and engine performance.
We offer both retrofit solutions for Tier 1–3 equipment and direct-fit replacements for Tier 4 and Stage V systems, backed by emissions testing and mechanical audits that reveal efficiency gaps and optimize fleet performance. Our in-house DPF cleaning and data logger analysis services give maintenance teams insight into emissions output, machine health, and operational trends, which reduce risk and maximize ROI.
Sound attenuation systems
Noise isn’t just a comfort issue; it’s a compliance and safety challenge. In mining, noise regulations must be met which can limit the expansion of mine sites around nearby communities, and excessive sound levels impact communication, worker concentration, and long-term hearing health. Mammoth’s Sound Attenuation Systems are engineered to reduce equipment noise at the source, improving environmental compliance, and overall productivity, all without compromising machine performance.
Our range of sound suppression exhausts, paneling, and enclosure systems are designed to meet or exceed regulatory limits while maintaining efficient exhaust flow and backpressure performance. From open-pit haul trucks to underground loaders, Mammoth’s sound control systems are tailored for the toughest operating conditions on earth.
We provide both direct-fit replacement mufflers and custom-engineered packages for specific equipment or site noise objectives. Whether it’s meeting MSHA, EPA, or ISO noise emission standards, or simply protecting your team’s hearing, Mammoth’s systems ensure you stay compliant, comfortable, and productive.
