Working together with a mining service provider, Hushpak set out to eliminate maintenance issues and ensure noise compliance for a CAT 793D haul truck. Hushpak replaced its original muffler with a custom designed muffler specifically developed to treat the problem frequencies associated with the CAT 3516B HD engine. The new muffler successfully reduced noise output to under the in service noise limit, and eliminated maintenance accessibility issues. Read more…

Hushpak designed and built a custom Acoustic Treatment System to attenuate noise levels from a Bradford Breaker. The solution incorporated Hushclad acoustic cladding, and achieved a 10dB(A) reduction in noise levels. Read more…
