Our critical range of exhaust silencer has been designed to meet the increasingly stringent noise criteria required in a pollution conscious environment.
Generally specified for use on two-stroke and four-stroke internal combustion engine exhausts, the units give good low frequency attenuation in the normal engine firing frequency ranges.
The units can be installed horizontally, vertically or inclined, without effecting efficiency.
The MA range of critical silencer can be used where good overall acoustic performance is required without a secondary or terminal silencer.
