An exhaust silencer or industrial muffler is a device that is used to reduce the noise of an engine's exhaust system. There are a variety of exhaust silencers on the market, each designed to offer different levels of noise reduction across a range of models.

Minetek's intake and exhaust silencers are designed and manufactured to suit all types of engines in industrial settings. These include stationary generators, pumping sets, compressors, ships, mining equipment, trucks and buses. Demand for heavy-duty exhausts and industrial mufflers for the mining industry has increased over the years based on our success rate and proven track record. Our innovative product range includes both reactive and absorptive designs suitable for industrial, residential and supercritical levels of sound attenuation.
