Minetek Sound was commissioned to design and implement a complete attenuation solution for a newly commissioned Caterpillar 993 loader. The objective was to deliver a significant noise reduction while maintaining OEM airflow, backpressure, and thermal performance, preserving both machine warranty and service life.
Our in-house engineers developed a customised M-STEALTH™ Sound Attenuation Package, purpose-built for the loader’s complex configuration. The result was a proven 5 dB / 5 dB(A) reduction in sound emissions for the Caterpillar 993 Loader.
