Sound Attenuators
A silencer may consist of single or multiple silencer units . Each full unit consists of two acoustic half-baffles and a central air passage. A silencer may be made up in several configurations using different unit sizes.
Operating principle and construction
The attenuators effectiveness is determined by the ratio of airway width to the splitter width, the splitters absorption coefficient and the attenuator length.
Syncro silencers use of faired airway entry and discharge sections reduce the airflow resistance giving the equipment a higher performance.
The casing of the standard sound Attenuators is made of galvanized steel of 20/22 swg. Splitters are made of a GI frame which is press formed. A 26 swg perforated aluminum sheet layer covers a high density tissue coated fibre glass. Pressure drop is reduced by a faired entry and exit nose.
Syncro square and rectangular attenuators are available in 4 types based on the airway gap.
Syncro range offers a great deal of flexibility with respect to size, performance and material specification. Our absorptive acoustic baffles in a duct-like casing, are proportioned for optimum performance
